ELECTROINDUCTIVE SENSOR OPERATING IN THE MEDIUM-FREQUENCY RANGE
(pp.46-51)

Abstract. The research work presents a structural analysis of an electroinductive sensor featuring ellipsoidal sensitive elements fabricated from a conductive material, which ensures high sensitivity and selectivity. The sensor operates on the principle of electric induction, utilizing the relationship of the current proportional to the electric field strength, enabling non-contact and precise measurement of field parameters. The developed design incorporates two semi-ellipsoids connected through a series resonant RC circuit tuned to the frequency of the investigated field, while the integrated electronic unit provides analog-to-digital conversion and digital signal processing with wireless data transmission. The proposed sensor is capable of rapidly detecting dynamic changes in the electric field with high accuracy and reliability, which is crucial for accident prevention, safety enhancement, and optimization of automated systems. Its architecture is compliant with the requirements of modern IoT and automation technologies.

Keywords: electrometric measurements, electroinductive sensor, ellipsoidal sensor, electric field strength, medium-frequency range.
