【Abstract】 On the base of the analysis of the principles of the differential capacitance sensor and the relationship between the output voltage and the varied capacitance values of the detecting electrode,the relationship between the varied ca- pacitance values and the micro—displacement of the gyroscope rotor is deduced and analyzed in this paper.This analy- sis proves that it is possible to apply the differential capacitance sensor to measure the deflection of the rotor and the scheme of this kind of measurement of the gyroscope rotor’s deflection with eight-electrode is presented.更多还原
