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 of the sensor. 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: in the center 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, containing a stiffening element connecting the adjoining tubes of the profile. Each profile tube contains ventilation hole placed coaxially with the ventilation hole on the side surface of the collar part.

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