Research on Eddy Current Field Characteristics of Eddy Current Displacement Sensor Based on ANSOFT

The eddy current field characteristics of the probe based on the eddy current magnetic field sensing principle of eddy current displacement sensor are the key to influence the performance of the sensor. In this paper, the eddy current field simulation of probe coils with different structures is performed. The effect of coil size and shape on the performance of the sensor is analyzed. The eddy current field characteristics of probe coils with different structures are studied. And build an experimental platform to test and analyze, verify the correctness of the simulation results, and lay the foundation for perfecting the eddy current displacement sensor theory and further optimization design.
