The composition and working principle of electronic platform scales

Many people buy electronic scales and they will all operate simply. However, many people do not understand the composition and working principle of electronic scales. The following is a small series of Shanghai Henggang to tell you about the composition and working principle of electronic platform scales.

Electronic platform scale construction:

Electronic platform scales are mainly composed of three parts: weighing indicator, weighing sensor, and scale body. Among them, the scale body is referred to as a mechanical, force-return resetting system between the object and the conversion element, including a carrier that receives the load of the object, a force-reducing resetting structure, a limit device, etc., which is the main carrier component of the electronic scale. , play a role in the weight of the object. The weighing platform and the transfer structure are responsible for the accurate transmission of the weight of the object to the load cell. A meter, weighing sensor installed in the middle of the platform bracket below the table, the weight of the object to be regarded as a function of a point is converted into the corresponding electrical signal, and then the electrical signal is transmitted to the secondary instrument, weighing indicator. After processing, the meter directly displays the weight of the object being weighed.

Electronic platform scale working principle:

The heavy object is placed on the weighing platform of the electronic platform scale. Under the action of the gravity of the object, the elastic body of the weighing sensor produces deformation. The weight passes the weight through the scale body to the weighing sensor, and the sensor converts the weight signal to the corresponding m. V voltage signal. This signal is amplified by a preamplifier. Filter filtering, A/D conversion, and the microprocessor displays the weight signal, the digital display directly shows the weight.
