Abstract: Electrostatic charge sensors are widely used in condition monitoring, fault prediction and health management of precision machinery and aero engines.The calibration technology of electrostatic charge sensor is introduced. Based on the oil droplet charging principle, combined with DC high voltage source, supporting fixture and charge measurement unit, the electrostatic charge sensor calibration system is developed.Through the oil dropping experiment, the relationship between oil charge and applied voltage, oil droplet size, temperature and humidity was obtained. The factors affecting the calibration equipment were analyzed.
