Development of a Cross Capacitor Electrode for Measurements of Liquids Dielectric Constants
액체의 유전상수 정밀측정용 크로스 커패시터 전극 개발
Abstract
Using the principle of the cross capacitor, a precise system for measuring the electric constants of liquids has been developed. The four electrodes of the cross capacitor were formed around fused-silica tube by plating a gold film. The effect of a non-uniform tube wall ok the measured permittivity was investigated As the individual characteristics of the tubes were determined to be constant, the pure dielectric constants extracted from any effect of the fused-silica material could be precisely derived with uncertainty of less than
