Modern scales: types of scales. What are the scales of the device and type

In a variety of areas - from household to industrial - can come in handy scales. Types of scales are very different, and they differ not only in their dimensions, but also in their functional characteristics and capabilities. Modern manufacturers offer the purchase of such devices of different types, size, design and configuration, depending on the specifics of their operation and purpose.

Mechanical

Depending on the type of weighing mechanism, all scales are divided into mechanical, electromechanical and electronic. The first work on the basis of the interaction of the lever system and the goods, while the information is displayed by an arrow mechanically linked to the system of levers. In fact, this is a traditional and familiar scales. Types of scales of this type attract attention at a low cost. But such devices require competent maintenance, since without operations for lubrication, cleaning and adjustment of such devices is indispensable.

Electromechanical

The weighing process in such scales is carried out by the interaction of the lever system with the weights, while the information about the cargo is output by means of an electronic device. Such devices are easy to read, but mechanical parts of the equipment wear out quickly. In addition, the repair of such scales is not simple.

Electronic

These are the most modern and easy to use scales. Types of scales of this type have a special weighing mechanism - based on a sensor that signals the load on the indicator. If you follow the rules of operation, such scales are able to last a very long time. The main requirement is to observe restrictions on weighing, that is not to exceed the specified weight. Otherwise, the sensor may be damaged.

Among the advantages of such devices, we can single out the simplicity of weighing, reliability and the ability to calculate the amount taking into account the price and weight of the goods automatically. In comparison with the models described above, electronic devices have better resistance to mechanical factors and displacement of the platform. But there are also disadvantages, which are expressed in the high cost of the sensor and the difficulties of its replacement.

For trade

There are at least 5 types of weights that are used in the sphere of trade. To them it is possible to carry:

• Packing;
• Commodity (for a warehouse);
• For counter-trading;
• For self-service stores;
• Scales with label printing.

The peculiarity of the trading scales is their equipping with displays, which can be up to 6 pieces. They are located either on the body or on a separate outrigger. Such scales are multifunctional, differ in thoughtful design and allow you to make calculations as clearly and competently as possible.

Types of trade scales

Any trading scales have a two-sided display, so that both the seller and the buyer can see the parameters of the goods being weighed. This is perhaps the most numerous scales on the classification. Types of scales for trade are as follows:

• Counterfeit devices calculate the cost of the goods after the data on the price per kilogram are entered, add up the cost of several purchases, and calculate the change.

• For self-service stores, special scales are offered that can mark goods and print checks (they print a label on which information about the product is displayed - its cost per kilogram, the final cost for the quantity of the weighed goods, expiration dates).
• Filling scales are widely used in shops, catering establishments, when packaging of piece goods is performed. Most models are types of electronic scales that can be used in the industrial sphere (when packing hardware), pharmacies. Such equipment can have special protection from dust and moisture or two-way indication of the mass.
• Commodity scales for a warehouse are the most massive devices capable of weighing goods from 60 kg to 2 tons. They are put on the floor, and their useful area is related to the maximum weighing limit.
• Scales with label printing function: widely used in self-service stores. Such devices are equipped with a thermal printer that prints self-adhesive labels. All the consumer's characteristics are indicated on them.

Postal

Postal scales differ in the accuracy of measurement, since they are associated with determining the weight of a parcel, parcel or letter. The most functional electronic models, which are more expensive. But they have numerous advantages:

• The scoreboard, which displays the weight of the mail product;
• The possibility of automatic selection of discreteness and limits;
• Good level of protective properties;
• Built-in self-diagnosis system;
• The ability to connect to a computer.

You can choose postal scales for both light and small shipments, as well as for bulky goods.

Industrial

There are various types of weights that are widely used in industry. Thus, platform devices are specific devices that are used by logistics companies, mail, manufacturing enterprises. All industrial scales are put on the floor and are cumbersome structures. They are designed specifically to weigh goods in various industries. Depending on the modifications, they can be mobile, shockproof, waterproof and dustproof.

Equally popular in the industry are scales such as wagon, crane, monorail, automobile. All of them are characterized by a massive construction and a large platform area, designed to weigh the dimensional goods.

Crane scales

Types, types of industrial equipment are pleasing to diversity. For example, a crane scale is a measuring device that allows you to measure the weight of a load in a suspended state. The use of such equipment is advisable in the ports of cities, metal stores, freight stations and industrial enterprises. Crane scales are characterized by weighing accuracy, load receptor (ladle, hopper), installation method (mobile, suspension), the way to achieve equilibrium. In terms of the measured load, the crane models are designed for a weight of 1 to 10 tons.

Such scales are mechanical and electronic. The latest models are more accurate and promising, although many enterprises are still equipped with mechanical equipment.

Automotive

These precision instruments are designed for weighing cars and road trains. It is advisable to use such scales in ferrous and non-ferrous metallurgy, food and chemical industry, agriculture and construction. Depending on the weighing method, the car scales carry out the measurement when the vehicle is fully loaded. Such systems are erected without foundations. Some models are designed to weigh individual axles of the car, after which the indicators are considered together.

Separately it is necessary to tell about portable automobile scales. They differ in light weight, low cost and well-designed dimensions, which makes it possible to install them for weighing in any area.

Pallet

This type of scales is designed for weighing cargo located on pallets. Such devices are widely used in warehousing and logistics facilities. These innovative designs are compact, but are used for weighing large loads. More often than not, the models are equipped with an electronic display, which makes managing the balance easier and more convenient. The load receptor in such scales is a U-shaped platform, in which 4 sensors are built in. With ease of operation, the equipment is very reliable, since there are no moving parts in it. In the standard version, pallet scales have numerous additional functions.

Household Options

Different types of weights can be used in everyday life, and they differ in various designs and design solutions. Depending on the type of device, there are with a weighing pan or with a platform with removable stands. Conventional scales with a bowl are used for weighing loose, watery products, with the use of an additional container is not required. Instruments with a platform are needed for measuring loads or objects of different dimensions.

The main types of weights used in everyday life are either mechanical or electrical. Particularly in demand are devices that allow us to determine their mass. Such devices are designed for a weight of up to 300 kg. Some modern models can be supplemented with a body fat analyzer. Special attention should be paid to the diagnostic scales.

In medicine

There are types of special weights that are used in the medical field. Such devices are always floor mechanical or electronic. In mechanical designs, the main element of the weighing device is in the form of a measuring spring. Of course, there is no need to speak about a high level of accuracy of such scales, therefore, an error is necessarily taken into account when measuring. Electronic devices for medicine are of different types:

• Simple - that is, with a digital display and mechanical stuffing;
• Increased accuracy.

It is clear that the accuracy of measurements in electronic scales will still be much higher. The scales on which newborns are weighed in hospitals and clinics are also considered to be medical. Such models have compact dimensions, a special platform for the location of the child and a display on which all the information necessary for the doctor is displayed.

For laboratories

Modern types of scales are highly accurate and allow measurements in various fields. Thus, laboratory devices are widely used not only in medicine, but also in laboratories of various enterprises, banks, jewelry shops. The peculiarity of them is that they can have additional functions.

For example, they perform hydrostatic weighing, that is, determine the density of liquids or solids, carry out dynamic weighing (measurement of non-static objects). Calibration in laboratory scales is carried out by external weights or in automatic mode. A distinctive feature of such devices is the presence of several units of measurement. And professional and expensive models have an expanded package of functions. Thus, it is possible to select models of weights for specific purposes and functional features.
