本文着重介绍了动压气浮自由转子陀螺仪使用的电容传感器的工作特性及其试验报告。为了改进差动式变压器绕组电感的稳定性,采用了环状铁氧体铁心。本文采用解回路方程的办法导出了该电容传感器的输出关系。在推导过程中考虑了差动式变压器绕组的分布电容,发现谐振点的频率f=1/2π L(C+2C_0)~(1/2)(其中C为分布电容),但工作点的频率必须远离输出特性曲线的峰值点。 This article focuses on the working characteristics and test reports of the capacitive sensor used in the air-floating free-rotor gyroscope. In order to improve the stability of the differential transformer winding inductance, using a circular ferrite core. In this paper, the solution of the circuit equation derived capacitance sensor output relationship. Considering the distributed capacitance of the differential transformer winding in the derivation process, we found that the frequency of the resonant point is f = 1 / 2πL (C + 2C_0) ~ (1/2) (where C is the distributed capacitance) Must be far from the peak point of the output characteristic curve.
