What’s the Working Principle of Digital Electronic Weighing?

With the intention of getting the hang of digital electronic weighing, this article mainly tells us the working principle as well as the main uses of digital electronic weighing in plenty of fields.

 

1.The Working Principle of Digital Electronic Weighing

When the object is placed on the scale, the pressure is applied to the sensor, which is an elastic deformation, so that the impedance changes. At the same time, the excitation voltage changes, outputting a change of analog signal. The signal is amplified by the amplifier circuit and output to the analog-to-digital converter, which is converted into a convenient digital signal and output to the CPU operation control. The CPU outputs this result to the display based on keyboard commands and programs until the result is displayed. It may look so simple but contain so many information.

 

2.The Functions Of Digital Electronic Weighing

Different functions of electronic platform scales are not the same. The function of electronic platform scale automatically sets zero at startup. It can manually peel/set zero, ac/dc power supply, digital display of weighing data. Besides, it can increase the weight accumulation--counting function, check the weighing function, dynamic weighing function, data recording function and control alarm function.

Optional output interface: RS-232 computer interface, a print interface, can be connected to the large screen display data fair. Electronic platform scale weighing has the ability to own high accuracy, quick response, weighing data display intuitive and eye-catching so that it really avoids all kinds of errors caused by visual errors.

 

3.Several Varieties of Digital Electronic Weighing

Waterproof scale

The waterproof design is carried out on the basis of the original scale, and the internal scale body structure is designed again according to the waterproof level. External scales, power cord interfaces, switches, etc. have been redesigned.

The Energy Scale

Energy scale is an innovation of traditional electronic scale and human scale. It does not need batteries and does not depend on solar energy. It uses mechanical energy converted into electrical energy to provide electricity for the weighing.

Waterproof scale

The waterproof scale has obtained waterproof certification. It can be all-round three-dimensional waterproof, with large Windows, and it is super anti-slip anti-fall, designed for the harsh environment of cold storage. Suitable for aquatic processing, seafood processing, fishery production, etc.

High precision counting scale

1. Kg/Ib unit conversion function;

2. the adjustment function of sampling rate (GLH series does not have)

3. zero point adjustment;

4. There were 10 groups of single memory function;

5. Simultaneous weight, quantity and accumulative function (GLH only accumulates quantity)

6. arning function with upper limit of weight and quantity;

7. Automatic zero tracking and temperature linear correction;

8. Function of weight deduction and weight prededuction

9. Standby function;

10. Zero display range and zero tracking range;

11. Battery voltage control limit function.

It is hoped that this article can help us understand the working principle and related uses of electronic scales.

All in all, the electronic scale has been applied in our lives for many years. What I think is that the electronic scale will be improved better.
