Summary: Based on the spatial magnetic field analysis of the planar coil, this study investigates the characteristics of impedance signals induced by debris at different positions in the coil under different frequencies, debris sizes, and velocities. The experimental results show that the double peaks in the induced signals can be eliminated without sacrificing sensitivity by placing the sensor channel at the coil inner wall. The sensitivity can be improved by observing resistance signals, increasing frequencies, and reducing debris velocities.

Summary: The importance of inductive debris sensor in online oil debris detection is increasing. This study proposes a new criterion for evaluating the performance of an inductive oil debris sensor: spatial resolution. Clear signals responding to each particle are vital when multiple metal particles pass through the sensor simultaneously. The spatial resolution refers to the allowable distance between two particles when the sensor can accurately distinguish the particle signals. Theoretical analysis and COMSOL simulation are conducted to investigate the factors affecting the spatial resolution and improve the sensor's accuracy of debris identification.
