According to the equivalent circuit of inductive wear particle sensor

formula of induction electromotive force of sensor is deduced

output characteristic of sensor is analyzed

through the finite element simulation software Comsol

sensor coil electromagnetic model is set up

using multi-factor orthogonal simulation test

inductive wear particle sensor coil spacing

width and diameter are analyzed and optimized. The experimental comparison shows that the peak value of induced electromotive force output by the optimized sensor is 4. 9 times that of the peak value of induced electromotive force output of the sensor before optimization

which significantly improves the monitoring effect of the inductive abrasive particle sensor on abrasive particles.
