Shenzhen Cooperation Sensors & Instruments CO,LTD. is a national high-tech enterprise specializing in force measurement Quick Response Continuous Product Innovation Whole Process Application Service What are the characteristics of inductive pressure sensors? An inductive pressure sensor is an instrument that uses changes in the inductance of an induction coil to measure pressure. Commonly used structures of inductive pressure sensors are air gap type and differential type. The working principle of the air-gap type is that the diaphragm is displaced by the measured pressure acting on it. When the air gap between the diaphragm and the magnetic core increases on one side, the other side decreases, and the magnetic resistance of the inductor coil also fWhat is the composition of the feeder electrical control system?
