“…7 Magnetic inductive debris sensors have met some success but are limited to debris larger than about 100 m in size. [8][9][10] The acoustic emission detection method based on the amplitude change in reflected acoustic waves is sensitive to interference caused by background acoustic emission and lubrication oil temperature variation. [11][12][13] Bulk capacitance sensing 14,15 uses a simple sensing structure; however the measured capacitance often reflects not only the presence of particles but also changes in total acid number and oil viscosity in the working fluid; this, in turn, creates difficulties in detecting debris.…”

We present the design, fabrication, and testing of a microfluidic device for metal wear detection in lubrication oils. The detection is based on the capacitance Coulter counting principle, that is, on the change in a microchannel's capacitance caused by the presence of a metal particle in the microchannel. The testing of the microfluidic device using 10-25 microm aluminum particles has demonstrated the feasibility for detection and counting of microscale metal particles in low-conductive lubrication oils. This microfluidic device is promising for online oil debris detection by the use of multiple detection microfluidic channels.

“…In 1980, the on-line detection of oil debris emerge [3], which used a magnet to capture and isolate the metallic debris from the flow path. K. W. Chambers designed an on-line wear debris sensor based on induction in 1988, in which the influence of the inductive current, oil temperature, oil viscosity, linear speed and wear debris size were studied and tested [4]. The result was the output of wear debris sensor is direct proportion to the electromagnetic material characteristics.…”

This 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. Based on the electromagnetic field analysis for the coil and particles, three structures of such sensors, classified by the number of coils, are available, and they all can detect, count or classify wear debris. However, the detectable particle size is mainly limited by the background noise. Accordingly, to enhance the sensor performance, the signal processing methods are necessary.

Wear 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 circuit of sensors. The experiments prove that the off-line sensor has satisfying accuracy and consistency for the concentration of the ferromagnetic wear debris, and the online sensor has effective detection capability for the granularity of the ferromagnetic wear debris and large unferromagnetic wear debris.
