To some, scales in the kitchen seem like overkill, but for a good housewife who loves to cook a lot and deliciously, accurate and reliable food scales are a must! Decided: buy kitchen scales! Just which ones to choose?
Criteria for choosing the best kitchen scales
Type of scales
All kitchen (and not only) scales are divided into 2 large groups: mechanical and electronic. A significant advantage of the former is low price and lack of power source. Electronic scales operate on mains power, batteries, or a rechargeable battery. Not only are they more accurate, but they can also have many additional useful features and attractive design.
Tara
The container can be a bowl or a platform. Both types have their advantages. The bowl is convenient for sequentially adding bulk and liquid products (for example, for kneading dough), the platform has more ample opportunities, since you can put a large product (uncut fish) on it, and place a bowl with dough or liquid.
Upper weighing limit
This is the maximum weight of the product that one or another scale can weigh. For different models it varies from 2 to 15 kg.
Weighing error
Weighing accuracy is essential for baking and complex gourmet dishes. In the best electronic scales, the error is 1-2 g, in mechanical scales - from 10 to 50 g.
Additional features
Necessary: taring (weighing the product without taking into account the container). Useful ones: sequential weighing, indication of overload and battery/battery charge, clock, thermometer, auto shutdown, volume determination, weighing of liquids, ability to mount to a wall. The function of counting calories in weighed products is interesting - it will be useful for those who often go on diets.
Which brand of kitchen scale is best?
Buyers recognize German kitchen scales from the Beurer brands as the most accurate and convenient, but their cost is approximately 2-3 times higher than their analogues. Inexpensive models produced by Polaris and Scarlett have proven themselves to be quite good. Redmond scales, like other kitchen appliances of this brand, connect to a smartphone. Chinese scales, represented by a wide range of brands, from famous to little-known ones, are optimal in terms of price-quality ratio and have all the necessary functionality.
The pharmacist's tool has become the talk of the town; it consists of two bowls: for the load and for the ingredients. Today we recommend buying kitchen scales, not mechanical ones, as in the hands of Themis, but electronic ones, which give the cook acceptable accuracy when weighing food. If you are interested in which kitchen scales are best to buy, you will see that the difference is small and insignificant.
What are kitchen scales for?
It’s easy to understand if the store was deceived. There are known cases when there are not enough goods even in the original packaging. Just come home and weigh the purchased products. Find out where to buy goods is not worth it.
Note! Miniature kitchen scales fit in a bag or bag. Take it straight to the supermarket and check the goods.
An experienced housewife knows what to do and how to do it; there are cases when you want to pass on a recipe to inheritance. For your daughter-in-law, daughter, etc. Kitchen scales will help you determine the dosage of ingredients with an accuracy of up to a gram. The difficulty comes when learning new recipes. There is no need to do it by eye, just take a kitchen scale and weigh out exactly as indicated. If the methodology is foreign, especially for this case, the models contain the option of switching to another measure generally accepted in the world community. For example, pounds.
Finally, a kitchen scale can help you stick to your diet. Doctors (nutritionists) prescribe the daily amount of calories, which you control when cooking. And you eat as much as you need. Especially for those losing weight, selected kitchen scales are supplemented with a built-in information base; at the same time, the energy value of the product is indicated along with the weight.
Other models allow weighing and volume determination. The function is limited in capabilities. Polaris PKS 0521, designed as an electric kettle without a lid, has a button to switch between flour, milk, butter, and water. This is needed for correct definition volume, although on the side wall there is also a scale with frequent marks. Let's add, vegetable oils endowed with individual specific density, we strongly doubt the accuracy of the measurements. However, this is enough for cooking.
Types of kitchen scales
A couple of nuances
When observing the Sinbo SKS 4513 kitchen scale, you will notice that the readings fluctuate. This semblance of real-time mode is not encouraging. For example, in the video, when a 50 g weight is placed on the platform, the number jumps. From our point of view, Maxwell models look much better, where measurements are taken for an acceptable time (a couple of seconds), then an indicator appears on the display showing that the mass of the load has been estimated. No further throwing. Although a bay leaf, for example, gives corrections. A breath of air due to the windage of the spice changes the reading by a fraction of a gram. Then the Maxwell kitchen scales will begin to work out variations in turbulence.
By the indication you can judge whether the measurements are completed.
Batteries for kitchen scales:
- AA batteries (finger-type).
- AAA batteries (pinky).
- “Tablets” at 1.5 V.
Price is important. In stores like FixPrice you can sometimes find batteries at an attractive price. It is better to evaluate the aspect in advance and choose kitchen scales according to the lowest expenses.
Finally, the price range on the counter is immense. It won’t be a mistake to buy an inexpensive kitchen scale. Firstly, manufacturers charge a lot for a big name, and secondly, kitchen scales are a product where quality plays a small role. The central electronic unit performs the simplest calculations, and the load cells are largely the same. Let’s say more – it’s not a shame to throw away an inexpensive kitchen scale if it breaks down.
If you buy a kitchen scale with a removable bowl, you will also get a good salad bowl. We remind you that plastic intended for contact with food products, marked with a fork and mug icon. Look for the pattern, or do not use the container for its intended purpose. Rare glass kitchen scale bowl. The material is heavy, relatively expensive, and there is no need for the product. Look for a compromise between price and quality.
We hope we helped you choose a kitchen scale. The main thing is to understand that the device is inexpensive, therefore, you shouldn’t pick too much on the properties.
Typical kitchen scale
Kitchen scales will allow home recipe measure accurately down to the gram, will help you study new and new dishes without fear. A typical device was priced at, for example, Maxwell for 800 rubles. The scale displays pounds, grams, kilograms or ounces, which allows you to flexibly handle ingredients when cooking.
Before buying an electronic kitchen scale, it’s easier to look through the instructions. Most manufacturers post information online.
Having tried it once, few people refuse. Modern technologies will allow you to find out the weight with an accuracy of 1 gram, which makes it easy to measure and weigh 15 bay leaves. Let's reveal the author's secret: when working with this kind of spices, place the ingredients in the bowl in the middle, wait patiently while the kitchen scale calculates. In Maxwell, the completion of the operation is signaled on the display by a triangle with bold dots at the vertices.
What is important for kitchen scales:
We recommend taking electronic scales, and you should not chase the price. It's easy to check the product. Go to a nearby supermarket, take a pack of 150 gram cookies and weigh them in the presence of a consultant. The difference in readings should not exceed a couple of grams.
If the difference is greater:
- Cheated in a supermarket with the weight of cookies.
- Libra lies shamelessly, you should choose scales from a different brand.
Should I take a kitchen scale that can count calories?
People often try to lose weight today. It is useful to choose the right products.
Kitchen scales with calorie calculations have a pre-built information base with tables of proteins, fats, carbohydrates and calories. For a number of models it is possible to enter your own numbers. Such models are used in conjunction with floor scales that can count body fat mass. As a result of weighing, in addition to the indications, a person is given recommendations on calorie consumption. Use the indicated number when cooking. The calorie content of the products has already been entered; all that remains is to add up the readings of the kitchen scale with a pencil. The prepared food is divided into portions, each person eats what is measured out.
It becomes easier to follow a diet; monitor the result with floor scales (often called “bio” for the ability to measure biometric parameters). We believe that action will contribute to the development of correct training program. There are nuances. For example, bodybuilders try to remove the skin when cooking chicken; the skin of the bird contains the lion's share of animal fats that are useless for pumping. White meat from the breast is considered valuable. It is clear that the simplest kitchen scales with calorie counting will not reflect such subtleties. In this case, the option of entering user data into the database is useful. The calorie content of foods can be easily obtained from the Internet.
Kitchen scales that count calories are more expensive.
Which kitchen scales to choose?
You will have to choose from the criteria design features platforms and bowls when it comes to kitchen scale form factor. We choose the first one - it’s more convenient to store. A bowl is needed when the container is removable. Then the scales easily turn into a platform that is convenient to store.
There are spoon scales and scoops in which the collected product is immediately assessed for its heaviness. In practice, it has been shown that units of grams can be weighed. The authors have a hard time understanding the purpose of such equipment—it’s too small.
Although kitchen scales are not considered an essential item, they have recently become very popular among modern housewives. After all, this device is useful thing in the kitchen, because it helps to facilitate the process of not only preparing your favorite dishes, but also homemade preparations. The most important indicator of any scale is weighing accuracy. How to choose wisely and how not to get lost in the variety of devices presented on store shelves?
What types of kitchen scales are there?
Kitchen scales, depending on the principle of operation, are divided into two types:
- mechanical;
- electronic.
The mechanical type of kitchen scale determines the weight of the item depending on the pressure applied to a special spring. They have a window with a dial and an arrow that shows the result of weighing the products. Although these scales are considered less accurate, they have some advantages:
- low price;
- work without additional food from the network;
- you can easily weigh a heavy object of large volumes, since the mechanical type device can withstand up to 20 kg;
- durability - it is not easy to spoil such a device, and in case of any breakdown, you can make repairs yourself.
The electronic type of kitchen scale has quite complex structure, which displays the result on a special display. This device requires mains power to operate. The price of electronic scales is much higher than mechanical ones, but this point is compensated by the advantages during use:
- weighing accuracy;
- great functionality;
- compact size;
- design.
Electronic scales come with or without a bowl. What are the best kitchen scales?
- scales with a bowl are a design that makes it possible to quickly weigh liquids or other products that are unable to hold their shape without additional containers, and the removable bowl can always be easily washed.
- scales with a flat, even surface. This device is convenient for weighing food and large items. In addition, you can put any weighing container on it.
Materials and design of kitchen scales
When choosing scales for the kitchen, you should also pay attention to the material from which they are made, and external design. The platform of the device can be either glass, steel, plastic or even wood. These materials do not have any special differences, so you can choose any of them, the main thing is that it matches the interior of the kitchen. For example, if the room is made in high-tech style, then it is best to purchase metal scales. They will fit perfectly into such an interior.
Advice! Choose kitchen scales only with or without a removable bowl, otherwise it will be difficult to clean the device.
The so-called slim models are in great demand among modern housewives. This is a thin and compact kitchen scale. Their small mass indicators do not affect weighing accuracy in any way. However, scales with a bowl are much more convenient to use, since they can be used to determine the mass of the dough and add the necessary products. In this case, the readings are reset to zero at each stage, thanks to which the amount of added ingredients is accurately determined.
Maximum weight and weighing error
One of the important characteristics of kitchen scales is, of course, the maximum weighing weight. It is this indicator that determines how many ingredients you can weigh at once. This characteristic on average ranges from 2 to 5 kg, depending on the model. If you regularly make preparations for the winter, then it is best to buy scales with the largest possible weighing mass. For other needs, a device capable of measuring products up to 3–4 kg is quite suitable.
One more at least important characteristic in kitchen scales is the accuracy of weighing. The smallest error of the device is 0.1 grams. However, you should not look for a device with exactly this indicator, since even an error of 1 gram is not particularly important.
What functionality can a kitchen scale have?
The advantage of any electronic scales is the functionality they have. Naturally, you will have to pay for each of the additional options, so immediately before purchasing, think carefully about whether you need these functions or not.
Most electronic scales have a tare option, which makes it possible to weigh products without taking into account the container in which they are located. The sequential weighing function helps you weigh products one after another without removing them from the container. Automatic switching off/on would also be a useful option. This feature will allow the device to turn off automatically if you do not use it for some time. It will also work on its own, provided that you place some object on its surface.
People who are constantly on a diet will truly appreciate the function of the built-in diet computer, which is able to provide information about the amount of protein, carbohydrates and fats in the product, as well as cholesterol and calories.
No less useful function is a timer that will inform you when the battery is low kitchen appliance. In addition, lovers of cooking dishes according to foreign recipes find it necessary to have a built-in option for selecting units of measurement.
Lovers of cakes and pastries know how the same product can taste different. And it’s not just about the secrets of confectionery recipes and the skill of professionals, but also about the accuracy of measured ingredients. Here, portion scales play one of the leading roles. Precision in a pastry kitchen affects taste qualities products in general. Mistakes can lead to excessive sweetness or, conversely, the lean taste of sweets, and the airiness and lightness may be lost. Dryness or excessive humidity can also contribute to loss of regular customers establishments.
Portion scales will help not only accurately weigh ingredients, but also the final product to determine its cost, package products of the required weight, check the weight of products taken into the kitchen, etc.
How to choose the right scales?
In a large selection of scales from different manufacturers you can get lost. The task will be facilitated by knowledge of production and technological processes preparations. Although the main purpose ancient invention- determination of weight, modern models equipped with many auxiliary functions that make working with them easier.
If you decide to purchase a reliable device for your production, you should pay attention to the availability of the following features in a particular model:
- percentage weighing and weight summation;
- dosing;
- automatic subtraction from tare weight indicators when weighing;
- automatic reset of indicators with installation after removing products from the scales;
- switching mode between grams and kilograms.
It will be useful to be able to print product labels with the necessary information, for example, packaging date and expiration date. For efficiency, it is necessary to have an automatic shutdown function, for reliability - various sources power: batteries, accumulators, connection to the mains.
Such a variety of functions makes the scale a rather complex apparatus that can facilitate work not only in the kitchen of a confectionery shop, but also in any production where there is a weighing process of up to 30 kg. These are the weight parameters that electronic portion scales are designed for. Of course, the more functions they perform, the higher their cost, but the ease of use of the equipment is also higher. You can save money by choosing a model from a little-known manufacturer. After all, large number advertising, which significantly increases the cost of products, is not always a guarantee of the reliability and durability of the equipment. A wide range of choices is available on the website ooopht.ru.
The second name for electronic portion scales is simple weighing scales. But, based on their versatility, this name does not correspond to reality.
Advantages of portion scales
The advantages of portable portion scales include affordability, reliability and durability. They have high accuracy rates, a weighing range from 120g to 30kg per different models, a wide range of their application: laboratories, jewelry workshops, kitchens of restaurants and cafes, shops and other industries. Scales of this type are distinguished by their small size, versatility and ease of use along with multifunctionality. Almost all models have a waterproof housing.
These characteristics guarantee long service life equipment and savings on maintenance.
All weighing instruments must meet metrological and operational requirements. The most important METROLOGICAL requirements for scales are weighing accuracy, sensitivity, consistency of readings and stability of the scales.
Weighing accuracy- the property of scales to measure the mass of goods with a deviation from the true value by an amount not exceeding the permissible error established by GOST.
The magnitude of the permissible error depends on the maximum weighing limit of the scales, the mass of the goods and is expressed in divisions of the dial scale.
Depending on the magnitude of the permissible error, table, platform, truck and carriage scales must be manufactured with an accuracy class of at least 1a (see Table 3.3).
Sensitivity- the property of scales to leave the state of equilibrium when the load increases by an amount equal to the largest permissible error. The smaller the mass they detect, the more sensitive and preferable they are for use.
Sustainability- the property of scales to independently restore balance after being deliberately removed from this position.
To the main OPERATING REQUIREMENTS These include maximum weighing speed, clarity of indications, compliance of the scales with the properties of the goods being weighed, and reliability of the scales.
Maximum speed weighing- the ability of scales to quickly determine the weight and value of goods when weighing and restore balance after removing the goods. Increasing the weighing speed on dial lever scales is ensured by the presence of vibration limiters and various braking devices that contribute to the accelerated damping of vibrations of the levers and pointers, and the rapid achievement of balance. Among lever scales, scales equipped with a vibration damper have a relatively high weighing speed.
Further improvement of the designs of weighing instruments is aimed at increasing the weighing speed, which is an important condition for increasing the productivity of sales workers and speeding up customer service. Highest speed Electronic scales are capable of weighing, thanks to the quick determination of weight, cost of goods and printing of a receipt.
Visibility of indications- good visibility and readability of scale readings based on weighing results. For better clarity of weighing readings, balance indicators are placed in the most visible place, painted or highlighted in bright contrasting colors. Dial scales are distinguished by good clarity of readings, since the indicator arrow and scale can simultaneously indicate the completion of the weighing process and determine the mass of the load. The best clarity of readings is provided by electronic scales, in which the weighing results are reflected on a digital electronic display.
Compliance of scales with the mass and properties of the goods being weighed means that the weighing limits of the scales must correspond to all possible weights of the goods. The design of the load receiving device must ensure convenience when weighing and correspond to the shape, size, structure and consistency of the product. For this purpose, load receiving devices are made in the form of a platform, platform, bucket, tray.
Reliability- serviceable and trouble-free operation of the scales throughout the entire period of operation, subject to compliance with its rules and conditions maintenance. The reliability requirement is also associated with the durability of the scales, which is characterized by the total operating time (or volume of operations) of the scales over its entire service life. According to the requirements of the standard, the full technical life of lever scales must be at least 15 years, optical - 10, electronic - 6 years.
CHARACTERISTICS OF THE MAIN TYPES AND TYPES OF SCALES
MECHANICAL SCALES
Mechanical table scales. Tabletop dial scales are produced with weighing limits from 2 to 10 kg. Compared to tabletop weight scales, they have a higher weighing speed and better clarity of readings. The mass of goods up to the highest limit of the scale is measured using a dial indicator without the use of weights.
The design of the desktop dial scales RN 10Ts13U is based on the simultaneous action of two levers of the first kind - a rocker arm (double, arched, equal-armed lever) and a quadrant (unequal-armed lever with a counterweight). This combination allows using weights to weigh on scales goods that have a mass exceeding the limit value of the dial scale.
The scale mechanism is assembled on a base plate with screw feet. It has a liquid level, lever vibration limiters, and two support posts. The freely rotating screw feet can be fixed with locknuts after reaching horizontal installation scales A double, arched equal-arm lever rests on the pillar cushions by two prisms. At the ends of the lever there are load-receiving prisms that serve as supports for the cylinders of the goods and weight platforms. Two rods are rigidly connected to the cylinders and are kept from tipping over by two bars. The bars have a hinged connection with the rods and the body of the scales.
The goods platform bar is connected by means of a rod to a quadrant on which there is a calibration weight and two rigidly fixed arrows. When a load is placed on the goods platform, the quadrant rotates to the appropriate angle and at the same time, parallel to both scales of the dial, the arrows indicating the weight of the goods move. When the load is removed, the counterweight returns the arrows and all moving parts of the scale to their original position. Adjustment of scales using a quadrant calibration weight is performed by specialists only during repairs.
In the cylinder under the weight plate there is a calibration cavity with small objects (ballast) for bringing unloaded scales to an equilibrium position (taring). An oil damper for the vibration of the lever mechanism and the scale pointer is installed under the goods platform. When the damper is adjusted correctly, the needles perform two or three periods of oscillation.
The scale mechanism is covered with a metal casing, in the upper part of which there are windows on both sides for taking dial readings. A seal with a state verification mark is attached to the screw connecting the parts of the casing. A locking screw is screwed into the base plate, which locks and protects the lever mechanism from damage when transporting the scales.
Mechanical commercial scales RN-6Ts13U weigh without the use of weights from 3 to 6 kg. Compensates container weight up to 000 g. Maximum weighing limit - 3 kg, error - 5 g, dimensions -500x290x600 mm, weight - 15 kg.
Stationary platform scales. Platform scales are used for weighing heavy and bulky cargo on unloading areas, automobile ramps and warehouses of shops and wholesale centers.
Scales installed at a permanent place of operation in such a way that their movement is impossible without dismantling are called stationary.
They are designed for weighing large loads and therefore must have good stability and strength. The mechanism of stationary scales is mounted on a special foundation. It consists of metal frame with flooring. The corners of the frame are reinforced vertical racks, with which it rests on two load-receiving levers. The load-receiving levers are connected through a system of transmission levers by means of a rod to a scale or dial reading device.
In warehouses and unloading areas for weighing goods transported on trolleys, in containers and large containers, it is advisable to use platform mortise scales RS-2Ш13 (scale) and RS-2Ц13 (dial). The scales are permanently installed in the receiving department so that the loading platform is at floor level. This makes it easier to load trolleys, containers, and stack other heavy loads onto the platform.
Commercial dial scales with large weighing limits can be equipped with a device for remote visual (using an electronic display) and documentary (printing on paper tape) readings. If it is necessary to obtain data on the total quantity of weighed goods, a remote sensor device is connected to a summing machine that records the mass of goods on an accrual basis.
Truck scales are used in warehouses of wholesale warehouses for weighing cargo together with the vehicle. The largest weighing limits for scales of various models can be 10, 15, 30, 60, 100 and 150 tons. The smallest weighing limit is 1/20 of the maximum weighing limit of the scales.
In trade greatest application We received scale truck scales RS-10Ш13А and dial scales RS-10Ц13А. They are placed in the cargo yard of the warehouse under a canopy, mounted in a pit so that the platform is at the same level as the access roads.
Truck scales can be mobile. They are used in procurement points and warehouses of wholesale centers. Automotive mobile scales RP-10Sh13 and RP-15Sh13 with the largest weighing limits of 10 and 15 tons are installed on the ground and special ramps are folded down from the platform for vehicles to pass through. The scale towing speed is 3-5 km/h.
Wagon scales are used in warehouses of wholesale warehouses for weighing cargo along with wagons. They are produced with weighing limits of 7.5-150 and 1-200 tons. The 150Ts13V scales have a platform measuring 15.5 x 1.8 m, on which rails with a track width of 1524 mm are laid.
Selected models stationary dial scales are made with recording devices for local or remote recording of readings, with a luminous display showing the weighing results.
Mobile platform scales. Libra not related to permanent place operation and are moved using vehicles or manually are called mobile.
Mobile platform floor scales used in warehouses for weighing cargo from 50 kg to 3 tons are called commodity scales. In trade, commodity scales are used with the following weighing limits: weight scales - 500 kg, 1, 2 and 3 tons; scale - 50, 100, 200, 500 kg, 1, 2 and 3 t; dial - 60, 100, 150, 300, 600 kg, 1, 2 and 3 tons. The lowest weighing limit on all commodity scales is 1/20 of the highest weighing limit. In accordance with GOST 11219-71, commodity scales are manufactured with a lever arm ratio of 1:100.
Commodity scales RP-1Sh13 differ from scale-weight scales in the absence of a weight holder and the presence of two scales - the main and additional ones. The main scale is applied to the surface of the rocker arm, the additional one is on a ruler rigidly connected to the rocker arm. Both scales have movable built-in weights, the movement of which balances the load. The maximum value of the main scale corresponds to the maximum weighing limit of the scales, and the additional value corresponds to the division price of the main scale.
Platform scales RP-150РШ13 are characterized by their low height due to the absence of a column and the location of both scales at the level of the scale frame. Due to their low weight (26.5 kg) and size, they are convenient for use in small warehouses and packing shops. The smallest weighing limit of the scale is 10 kg.
Commercial dial scales RP-500TS13 allow you to determine the weight of the load on the dial scale without any calculations. Scales consist of three main mechanisms: load-receiving, intermediate and dial. The load-receiving mechanism of dial scales does not differ from the similar mechanism of scale-weight scales.
The intermediate mechanism is placed in the weight column and consists of two levers - lower and upper. The lower lever, hingedly attached to the scale column, is simultaneously connected by rods to a large subplatform lever and the upper lever of the intermediate mechanism. The upper lever, resting on the stand, has a calibration weight at the end of the right arm, and a weight holder at the end of the left arm. In addition, the lever is connected by a rod to a locking device, an oil vibration damper and a dial indicator mechanism.
On the scale column there is a handle for applying and removing weights when weighing. Simultaneously with the movement of the applied weights, a digital designation corresponding to the mass of the applied weights appears in the dial indicator window.
Some models of dial scales are equipped with a device for balancing containers, built-in printing and summing machines and devices for remote recording of readings. In a printing and summing machine, the result of one weighing, the total result of several weighings and the date are printed on a special paper tape. Printing is carried out simultaneously on operating and control tapes, as well as on an expenditure or receipt document. If there is a remote recording device, the mass is determined not visually, but at a distance from the weighing device according to the readings of one plumb line or the sum of several plumb lines printed on the tape.
INSTALLATION AND OPERATION OF MECHANICAL SCALES. Before use, all measuring instruments must be installed on a flat, strong horizontal base that does not bend under the weight of the scales at the highest load. The horizontal position of the scales is determined by the plumb line or liquid level.
To install tabletop dial scales by level, first screw in the adjusting feet until they stop, and then, gradually unscrewing them, adjust the air bubble to the center of the level control ring. Rotate the legs in pairs on the side opposite to the location of the bubble. For example, when the bubble moves to the right side of the level, the left legs are unscrewed and vice versa. After completing the adjustment, use locknuts to secure the legs in a stable position.
A properly installed unloaded scale should have both hands on the same dial division. Deviation from the equilibrium position can be eliminated by changing the weight of the ballast (metal scrap) in the calibration chamber or by rotating the calibration weight (counterweight) along a screw thread in one direction or another. Scales whose balance cannot be achieved by taring are subject to removal from service. Adjusting the pointer to the zero division by rotating the adjusting feet is prohibited, since in this case the weighing readings will be distorted.
After installing the dial scales, the oscillation frequency of the pointer is adjusted by rotating the outer cylinder of the oil damper. When unscrewing, the oscillation frequency of the arrows increases, and when screwing it in, it decreases. If screwing the cylinder to the limit does not affect the oscillations of the hands, you should add oil (transformer or sewing oil) into it. The adjustment of the oscillation damper is considered correct if, when a load is applied, the arrows stop at the corresponding division after two or three periods of oscillation.
Before weighing, make sure that the scale is installed horizontally and that balance is restored quickly. When applying a load, all closure devices (lock, insulator) must be in the closed position. The load is placed carefully, avoiding sharp shocks and impacts, as close as possible to the center of the load receiving area, so that the goods do not come into contact with the scale body and other objects.
After correct installation load, open the shutter, balance the load with overhead weights or by moving the weight along the scale (depending on the type of scale) and take weighing readings. On dial scales, the mass of the load within the scale is determined without the use of a weight according to the indications of the dial arrow.
It is not allowed to cut food or unpack or pack cargo on the weighing platform of the scale. The weighing limits established for this scale must be observed. When weighing goods in containers, it must be balanced special device or equivalent cargo. During the weighing process, use weights from the kit supplied with the scales.
After weighing, close the shutters, and then carefully, avoiding sudden vibrations, remove the weights and load. Scales and weights must be stored in clean condition, protecting them from dirt, dust and dampness. It is especially necessary to monitor the cleanliness of the loading area after weighing bulk or wet goods. Scale parts must not be cleaned with hard objects (knives, files) or lubricated with any kind of oil.
ELECTRONIC SCALES
Electronic table scales. Electronic table scales are designed for weighing goods during the packaging process or immediately before releasing them to customers. Retail and wholesale trade enterprises use electronic scales of domestic and foreign production. Characteristics of some models are given below.
Universal electronic scales VNU2/15 designed for weighing various goods weighing up to 15 kg inclusive. They are produced in two types:
* with display of information about the weight of the cargo;
* with display additional information about the unit price of cargo and the total cost.
The principle of operation of the scales is as follows: ten-sensitive quartz resonators, under the influence of the measured load, change the frequencies of their own oscillations. The difference between these frequencies is converted into a sequence of electrical pulses, the frequency of which is measured electronic unit. The result of the frequency measurement, expressed in units of mass, is displayed on the indicator.
Tabletop electronic commercial scales BP4900 included in the State Register as complying with those in force in Russia technical requirements and GOST standards.

Electronic commercial scales with built-in printer very convenient for packaging goods. Electronic scales have become widespread on the Russian market. trading companies SAZ. BP type scales are used in wholesale and retail, public catering, food and meat processing industries for weighing and packaging grocery, confectionery, meat, fish, vegetables, fruits, semi-finished products.
The scales are intended:
To determine the weight and cost of goods;
For printing labels with product information.
They are provided with a simple and accessible programming device for entering information: about the product - name and information (composition, presence of preservatives, preparation method, etc.), price, shelf life, container weight, number and code of the product type; about the store - name, address, date and time of sale, department number.
In addition, it is possible to set the required label format and font type. Using 54 price keys, you can recall the necessary information from the memory of the scales and control the movement of goods across groups and the store as a whole. Data can be obtained both at the end of a work shift and during the process of selling or packaging goods.
Packing scales VP-15F are designed for weighing goods during packaging, calculating the cost and generating the corresponding barcode, followed by printing the results on self-adhesive labels and on tape made of thermal paper. Packaging of goods is carried out with the output of programmed data on the label. The product name is displayed on the alphanumeric display. Quick access to product characteristics is carried out using eight keys. It is possible to remember prices and basic characteristics of up to 999 products. The maximum weighing limit is 15 kg. The printing speed of one label is no more than a second. Weight -10 kg.
Electronic floor scales. Floor scales are used at different stages of the product distribution process - transportation, warehousing and sales when weighing raw materials, semi-finished products, finished products, goods. They are used at unloading sites, warehouses, wholesale and retail trade enterprises, and public catering. Below are characteristics of individual models.
Electronic floor scales VU-3/150 are designed to determine the mass and cost of cargo with a weighing limit of up to 150 kg. The scales can be connected to a computer with the ability to maintain a database of automated accounting of goods acceptance and release, a cash register and other peripheral devices. The smallest weighing limit is 0.2 kg. Platform dimensions - 600x400x150 mm. Stand height - 990 mm. Weight - 30 kg.
Platform strain gauge scales type VPN consist of a goods receiving device and a weighing terminal. The goods receiving platform is installed on four sensors that sense the amount of mass of the cargo placed on it.
The principle of operation of the scales is based on converting the gravity of the goods being weighed into an analog signal at the output of force measuring sensors and subsequent digital signal processing in a microprocessor terminal with the output of the result on the display board and the output connector for communication with external recording devices via standard interfaces.
The weighing terminal has the following built-in functions: tare, zero setting, dosing of mixture components, “gross” and “net” modes. The terminal is controlled via a 16-key alphanumeric keyboard. The terminal has vacuum-luminescent indicators, as well as an additional indicator for displaying the total weight and number of weighings. The scales have access to external recording devices (printer and computer).
* extremely low platform height, allowing
* increased corrosion resistance and structural reliability due to the use stainless steel;
* high weighing accuracy, not inferior to analogues of well-known foreign companies;
* the presence of a modern weighing microprocessor terminal with parallel and serial interfaces for printing results and entering them into a personal computer;
* low weight of scales, allowing you to easily move them from place to place;
* absence of moving and wearing parts and assemblies.
Electronic scales floor type DL from CAS have an interface for connecting a computer. The main functions of the scales are:
* determination of the mass of goods;
* determining the number of parts by their weight;
* weighing goods within specified limits;
* compensation of tare weight from the weighing range.
The scales are powered from a battery source or from the mains via an adapter.
The principle of operation of scales is to generate an electrical impulse proportional in power to the force of gravity of the goods being weighed. This function is performed by a strain gauge, from which information is reflected on the display in the form of digital readings.
Installation and operation of electronic scales. The scales can be used both indoors and outdoors at a maximum ambient temperature of no more than 40°C, a minimum of -5°C, and air humidity up to 90%.
Placed on a flat, stable surface of a counter, production table, or floor, providing customers with an overview of the platform and display (board). By level, by rotating the screw supports, a horizontal installation of the scales is achieved (the air bubble should be in the center of the black ring). Before turning on the scales, the platform is freed from load and compliance is checked
mains voltage and operating voltage of the scale. Then insert the power cord plug into the socket and after 5-10 minutes, depending on the scale model, weighing begins.
