  ABSTRACT: In the mathematical model of electrostatic sensors established by Yan Yong in previous studies, the thickness of the insulating layer was not taken into account in the model. In order to study the static monitoring of electrostatic sensors in more depth, this paper considers the influence of insulation layer when establishing the mathematical model of the sensor. By establishing a mathematical model, the point charge measurement model was deduced and formulated. By studying the sensitivity of the sensor, it is concluded that the sensor insulation layer must be considered. The thickness of the insulation layer reduces the sensitivity of the sensor, and the relationship between the sensor spatial sensitivity and the grinding particle size distance is obtained. Compared with the models established by the predecessors, it is concluded that the mathematical model constructed in this paper is feasible and reliable. For the future research of electrostatic sensors.
