CAPACITIVE INTERFACE LEVEL SENSOR Russian patent published in 2022 - IPC G01F23/26 

FIELD: measuring.

SUBSTANCE: invention is intended for measuring the levels of interfaces between media in various industries. The capacitive level sensor of the media interface contains a base and a sensitive element. The base contains the first part containing a niche with a cover for hermetic placement of the electronic computing unit and a hole for the output cable of the electronic computing unit, and the second part, which is centered in the area of the first part has holes for embedded bushings; on the side surface has holes for fasteners and ventilation holes. The sensitive element of the sensor is a housing for electrodes, which is a metal profile formed by connecting several tubes to each other. Each profile tube contains a vent located coaxially with the vent on the side surface collar part, and contains a slot. The housing for the electrodes contains electrodes in each of the profile tubes, which are metal tubes with the same linear capacity, but differing in length.

EFFECT: technical result is an increase in the reliability and manufacturability of the design and, as a consequence, an increase in the accuracy of measurements of the level of the interface between media.
