Detailed Description
The working principle of the eddy current sensor is as follows: as shown in fig. 1, when the power is turned on, a high frequency signal is emitted by the eddy current sensor, so that an alternating magnetic field is generated at the sensor head, and if no metal conductor 6 is close to the magnetic field, the energy in the range is released; if a metal conductor 6 is close to the probe, the alternating magnetic field generates an eddy current field on the metal surface, and the eddy current field generates an alternating magnetic field opposite to the magnetic field of the probe. Under the interaction of the two magnetic fields, the amplitude and phase of the high-frequency current of the probe are changed, namely the effective impedance of the probe is changed, as shown in fig. 1: therefore, the measured metal surface needs to be changed continuously, otherwise, the impedance is a fixed value, and the damage of the vibration probe cannot be corrected if the voltage and the current are not changed.
