1. Working Principle Sensors are generally composed of four parts: sensitive elements, conversion elements, conversion circuits, and auxiliary power supplies. 1. The sensitive element directly senses the measured quantity and outputs a physical signal that has a definite relationship with the measured quantity; 2. The conversion element converts the physical signal output by the sensitive … Read more
