A design of oil debris monitoring and sensing system

The oil debris sensor has been widely used in the fault detection of mechanical equipments. However, some key parameters used in the sensor have not been solved in theory, such as the estimation of solenoid coil turns. A new method to optimally determine the coil turns is proposed in this work. In addition, the circuits system for detecting debris and sensing signals have been also developed. Experiments for detecting micro debris by using the designed sensor system well demonstrate its effectiveness.
