Instrumentation circuitry for an inductive wear debris sensor
10th IEEE International NEWCAS Conference, 2012The design of instrumentation circuitry for an inductive sensor to detect small metal particles is presented. The sensor, designed for counting and characterizing wear debris particles in lubrication oil, detects changes in the inductance of a small coil as metal particles pass through it.

The key points of inductive wear debris sensor
Proceedings of 2011 International Conference on Fluid Power and Mechatronics, 2011This review paper has presented several examples of inductive wear debris sensor. Many of these have important applications in industry. Thus, when monitoring the oil system which operates under extremely severe conditions and various features (size and type) need to detect, it is worth considering the use of inductive wear debris sensor.

Radial inductive debris detection sensor and performance analysis
Measurement Science and Technology, 2013Mechanical systems are prone to wear which can cause catastrophic failure if not detected and corrected in a timely manner. Hence, debris detection (type and concentration) is important for fault diagnosis and life prediction of hydraulic systems. The paper presents a new inductive method for debris detection based on a radial magnetic field.

An Inductive Particle Detector Debris Sensor Based on Multiple Excitation Coils
2019 International Conference on Sensing, Diagnostics, Prognostics, and Control (SDPC), 2019During the operation of mechanical equipment, the wear of the tribol-pair will cause the debris to enter the oil system and circulate in the oil system. The characteristic information of the debris can reflect the health status of equipment. Therefore, it is an effective method to monitor the operating state of mechanical equipment by detecting the ...

Study on oil detection technology based on inductive wear debris sensor
2009 9th International Conference on Electronic Measurement & Instruments, 2009Wear debris concentration and granularity in the lubricant oil contains the information about wear condition of machine. Based on the inductive balance principle and the detection requirement of wear debris, the off-line wear debris sensor and the on-line debris sensor are designed. And some measures of low noise design are used in the signal detection
