The debris detection system is simulated and analyzed with the software of Maxwell 14 in this paper. The magnetic induction intensity and the magnetic density of the detection system with metal debris are simulated. The static experimental system is designed to measure the inductance caused by different metal debris. The simulation and experimental result indicate that the nonferromagnetic metal debris reduces the inductance of microplane inductance sensor and that ferromagnetic metal debris increases the inductance of microplane sensor. The detection of metal debris with microplane sensor is feasibly proved by the research. This paper provides a model for detecting the debris with a plane eddy current sensor and a case for the 3D simulation of the eddy current. This work may have some significance for improving the efficiency of the plane eddy current sensor.
