Korobko O. Improvement of resonance dielcometrics method of control and determination of moisture content liquid nonpolar dielectrics.

The important scientific and practical task of increasing the sensitivity of resonance dielectometric method is solved in this work. This was achieved through the development and implementation of new multi-frequency varieties of resonance dielectric method for measuring the humidity of an emulsion type liquid nonpolar dielectric water, which takes into account the parasitic capacitances of the measuring generator and converter. The mathematical model of the emulsion on the basis of artificial Kok insulator was also proposed and studied, its application areas were determined on the basis of moisture and frequency, and its systematic errors were determined. The requirements for the means of implementing the most sensitive multifrequency method are defined. A new type of measured transducer based on a stepwise nonuniform coax resonator is proposed, its main characteristics are determined. Experimental studies of the measuring converter on its basis have been performed, the results of which confirmed the possibility of implementing the most sensitive multifrequency method. For experimental studies moisture meters of the medium frequency and very high frequency range have been created, and the experimental research methodology has been developed. The results of the experimental measurements of moisture in liquid nonpolar dielectrics allow us to conclude that the proposed approaches enable us to achieve the goal.
