Exploration of the Teaching of Eddy Current Sensors Based on COMSOL Simulation Software
In order to improve the effectiveness of classroom teaching and assist students in understanding the detec-tion principle and related abstract concepts of eddy current sensors,this paper uses COMSOL simulation software to construct a simulation model of the probe coil of the eddy current sensor,and uses the finite element analysis method to solve and calculate it.Through the analysis of simulation results,students can intuitively see that when the excitation frequency,lift-off distance,inner diameter,outer diameter and thickness of the eddy current coil change,the detection sensitivity of the eddy current sensor will change accordingly,which helps students under-stand and master the relevant knowledge of eddy current sensors,and improves their enthusiasm for learning and depth of thinking.
