Principle, Classification and Application of Electronic Scales

Electronic scales are a type of scale. Scale is the use of Hooke's law or force lever balance principle to determine the mass of objects, according to the structure principle can be divided into mechanical scales, electronic scales, an electromechanical combination of scales three categories. Electronic scales are mainly by the weight-bearing system (such as scales, scales), force transfer system (such as lever force transfer system, sensors), and display value system (such as dial, electronic display instrument) 3 parts.

Principle of electronic scale 

In weighing, the metal frame of the electronic scale is deformed by the force, the metal wire on the patch is also stretched or shortened, and the wire resistance is therefore changed, by measuring the change in resistance of the wire, the data of the weighed weight is obtained. The electrical parameters obtained from the deformation of the wire, after the amplification circuit, zeroing circuit, analog-to-digital conversion (A/D conversion), and after the decoding circuit to drive the digital tube display figures.

In simple terms, the electronic scale collects the weight through a pressure sensor and converts the collected weight information into standard kilograms through an electronic chip, which outputs the numbers from the display. The core original is the strain gauge, a metal frame to which a patch of coiled wire is attached.

Classification of electronic scales

Waterproof scales

With the development of electronic scales and the demand for special applications, waterproof scales came into being. A waterproof scale, as the name implies, is waterproof. Waterproof scales vary in their waterproof performance depending on the level of waterproofing. Some waterproof weighing scales are waterproof to the highest IP68 level and can be weighed even when soaked in water.

The waterproof scale has a fully sealed structure inside to prevent corrosion of the sensor elastomer from corrosive liquids, vapors, etc., greatly improving the life of the sensor. The purpose of waterproof scales is to be waterproof and moisture resistant to deal with those harsh environments such as humidity and salt spray. Waterproof scales are generally divided into waterproof counting scales, waterproof counting scales, waterproof electronic bench scales, etc.

Waterproof Price Scale

Waterproof design is based on the original price scale, the internal structure of the scale is redesigned according to the waterproof level. The external scales, power cable interface, switches, etc. are redesigned.

Energy Scale

The energy scale is an innovation of the traditional electronic scale and human scale, which does not require batteries and does not depend on solar energy. It uses mechanical energy converted into electrical energy to power the weighing.

Waterproof Weighing Scales

Waterproof weighing scale obtained waterproof certification all-round three-dimensional waterproof, large view window, super anti-slip, and anti-drop, designed for cold storage harsh environment. Suitable for aquatic processing, seafood processing, fisheries production, etc.

Applications of electronic scales

Different functions of electronic bench scales are used in different ways. The electronic bench scale features automatic zeroing on, manual tare/zeroing, AC/DC power supply, digital display of weighing data, weight totalization function, counting function, check weighing sub-check function, dynamic weighing function, data recording function, control alarm function.
