4、 Working principle:

Sensors are installed in electronic weighing equipment such as automobile scales. When force is transmitted to the sensor, the resistance of the internal circuit of the sensor changes, and a voltage signal is generated through a Wheatstone bridge. The voltage signal is converted into a digital signal through A/D conversion. The built-in intelligent module can linearly adjust, compensate and calibrate the digital signal, and can be easily connected to instruments or computer terminals for high-precision weighing detection.
