FEATURES OF CALCULATION AND RESEARCHES BY CAPACITY SENSORS DIELECTRIC PERMITTIVITY WITH DIFFERENT ELECTRODE FORMS

Abstract

In the course of the calculations and analysis of experimental data, the possibility of designing capacitive sensors with plates of complex configuration (square, rectangular and round) was established, provided that one of the plates remains stationary, while the other is moving in a parallel plane relative to the stationary. The experimental researches confirmed the patterns of capacitance change of the sensor from the magnitude of the dielectric insight of the medium and the geometric parameters of the plates of this sensor. It is shown that: for a square shape of the cover, with a uniform increase in the area of their overlap, the capacitance of the sensor increases according to the parabolic law; for a rectangular form of the cover, with a uniform increase in the angle of the overlap of the plates, the capacitance of the sensor increases tangentially; for combined (moving rectangular and fixed circular) shapes of the plates, with their uniform motion, the capacitance of the sensor increases with hyperbolic law. Due to the high accuracy of the results of experimental studies of dielectric insight of materials, opportunities for further research on the homogeneity of these materials and the possibility of identifying internal defects that may appear in the process of manufacturing products in violation of production technology.
