The Lubrication Oil Wearing Particles Monitoring System with Three-coil Inductive Sensor

Abstract

In the lubrication oil of the machinery devices, metal wearing particles reflect the wearing state in real time. Therefore, lubrication oil wearing particles monitoring system can identify the health state of the machinery devices. Based on the three-coil inductive sensor, this paper proposes the monitoring system including the exciting circuit, the detection circuit, the MCU system circuit and the host PC software. Experimental result shows that the proposed monitoring system can captures the output signal of the metal wearing particle.
