• Ferromagnetic wear particle
• electromagnetic sensor
• iron content monitor

This article introduces a detection method and apparatus for rapid detection of the content of ferromagnetic wear particles in the lubricating oil, as well as the signal processing circuit. Moreover, an electromagnetic sensor of transformer type is used; meanwhile, the content of ferromagnetic substances in the lubricating oil is detected by the detection of changes in relevant parameters of the electromagnetic sensors based on the fact that the existence of the ferromagnetic wear particles has resulted in the changes in spatial distribution of the magnetic field. Finally, the influence of non-ferromagnetic pollutants may be eliminated and a high linearity may be achieved with low cost and good real time.
