METHOD OF MEASURING PARAMETERS OF DIELECTRICS DURING HEATING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G01R27/26 

FIELD: measuring equipment.

SUBSTANCE: method of measuring the parameters of dielectrics during heating in a volumetric resonator at a fixed frequency includes excitation of oscillations in the resonator through the communication holes located in the upper end wall in the cooled part of the resonator, tuning the resonator into resonance under normal conditions and under heating and measuring the intrinsic parameters of the empty resonator, sample set to the movable lower piston, tuning the resonator into resonance under normal conditions and under heating and measuring the parameters of the resonator with the sample, calculating the temperature parameters of the dielectrics by comparing the intrinsic temperature parameters of the empty resonator and the resonator with the sample, characterized in the fact that the resonance tuning of the hollow resonator and the resonator with the sample is carried out by moving the upper end wall of the resonator with coupling holes at a constant position of the movable lower piston.

EFFECT: providing the possibility of higher accuracy in measuring the parameters of dielectrics.
