Features
Inductive sensor is an electronic detection device with metal detection function that made based on the eddy current effect of metal conductor and the electromagnetic induction characteristics of metal coil. The sensor is mainly composed of oscillator, trigger circuit and output circuit. When a metal object approaches the sensing surface of the sensor, the trigger circuit will act to generate a digital output signal as the oscillation amplitude of the oscillator drops to a certain value. It has the advantages of simple design, high sensitivity and resolution, good repeatability and linearity. The sensor is widely used to measure displacement, pressure, flow, etc. in industrial automation applications.
