Resonator Method For Measuring Dielectric Permittivity of Gas Substance

Abstract

A functional scheme for measuring the dielectric permittivity of plant gas substance was validated. A method for measuring dielectric permittivity of plant gas substance based on measuring changes in the resonant frequency of a measuring resonator, the method includes using the resonator device as a frequency discriminator. The use of a resonator device as a frequency discriminator determines the principle of construction of the frequency conversion system. In such a system, frequency conversion is based on frequency autotuning of a frequency-stabilized generator to the frequency of the measuring resonator.
