Tips: The Working Principle of Inductive Proximity Sensor.

Through the influence of the external magnetic field, the magnetic loss caused by the eddy current generated on the surface of the conductor is detected. A method in which an AC magnetic field is generated in the detection coil, and the impedance change caused by the eddy current generated by the metal body of the detection body is detected.

In addition, as another method, it also includes an aluminum detection sensor that detects frequency and phase components, and an all-metal sensor that detects only the impedance change component through a working coil.

On the surface of the detection body and the sensor, the state of the transformer occurs.
