Displacement sensors, also known as linear sensors, are divided into inductive displacement sensors, capacitive displacement sensors, photoelectric displacement sensors, displacement sensors, ultrasonic displacement sensors and Hall displacement sensors. Inductive displacement sensor is a linear device, which belongs to metal induction. When the power supply is turned on, an alternating magnetic field will be generated on the induction surface of the switch. When a metal object approaches the sensing surface, an eddy current will be generated in the metal, which will absorb the energy of the oscillator and linearly attenuate the output amplitude of the oscillator, and then the object can be detected in a non-contact manner according to the attenuation change.
It is recommended that Shanghai Xingyu Hi-Tech Applied Technology Research Institute is a professional manufacturer of displacement sensors.
