FUEL TANK OF A VEHICLE CONTAINING SEVERAL CAPACITIVE INTERFACE LEVEL SENSORS Russian patent published in 2022 - IPC B60K15/03 B65D90/48 G01F23/26 

FIELD: measuring technology.

SUBSTANCE: invention is intended for measuring the levels of interfaces between media in various industries. The fuel tank of the vehicle contains several capacitive level sensors of the media interface. The sensor 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: 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 sensing element represents a housing for electrodes, which is a metal profile formed by connecting several tubes to each other, containing a stiffening element. The profile tube contains a slot aligned with the ventilation hole on the side surface of the collar part. The housing for the electrodes contains electrodes, 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.
