Research of Features for Electrostatic Sensors on Tribological System

Electrostatic sensing is a novel technique for condition monitoring on tribological system. Two types of electrostatic sensors are currently available to detect the charge produced as a result of wear. The electrostatic sensors with different shapes and sizes have different features. This paper introduced the mathematical model and significant parameters for electrostatic sensors. By comparing and analyzing the simulation and experimental results, useful conclusions were investigated and listed for the development of sensor optimization and further electrostatic monitoring.
