Investigation of biparametric resonance sensors with distributed parameters

Abstract

This article describes the ways to preserve the resonant mode in biparametric circuits with distributed parameters and studies the effect of changes in the circuit parameters and power supply on the resonant mode. During the moving part’s movement of the sensor due to the influence of the distributed magnetic resistance of the steel part of the circuit, the law of change in the electrical inductance of the resonant circuit (distribution of magnetic flux in long magnetic conductors) differs from the linear one.
