电感式磨粒传感器由于能够真实的实时监测设备的磨损状态而得到了广泛的研究。为了更精确地检测磨粒，本文提出了一种基于环形磁场下多个感应线圈的磨粒传感器。感应线圈靠近较强的磁场，传感器不仅可以保证流量，而且还可以提高磨粒检测精度。本文讨论了信号与磨粒速度和激励电流之间的比例关系。通过单颗粒实验和润滑油动态实验研究了不同电感线圈间的串扰现象。在动态油液实验中，该传感器在570 mL/min的流量下检测到13 μ m的颗粒，满足大多数工业在线监测的要求。
Inductive wear particle sensors have been widely studied due to their ability to monitor the wear status of equipment in real time. To detect wear particles more precisely, a wear particle sensor based on multiple inductive coils under a toroidal magnetic field is proposed in this paper. With inductive coils located near a stronger magnetic field, the sensor can not only ensure the flow rate, but also enhance wear particle detection accuracy. The proportional relationship between the signal and the wear particle velocity and the excitation current is discussed in this paper. The crosstalk phenomenon among different inductive coils was also investigated by single particle experiments and lubricating oil dynamic experiments. In the dynamic oil experiment, the sensor detected 13 mu m particles under a flow rate of 570 mL/min, which satisfied most industrial online monitoring demands.
