SENSITIVE ELEMENT OF CAPACITIVE LEVEL SENSOR OF INTERFACE( 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 sensitive element of the capacitive interface level sensor, which is a housing for electrodes, which is a metal profile formed by connecting several tubes to each other, containing a stiffening element connecting the adjacent tubes of the profile. In addition, each profile tube contains a vent located coaxially with the vent on the side of the collar. At the same time, the body for electrodes contains electrodes rigidly fixed in each of the profile tubes, which are metal tubes with the same linear capacity, but differing in length, and the main electrode is made along the length equal to the length of the body for the electrodes, and each compensation electrode is made along the length less than the length of the main electrode. The sensing element is configured to be connected to the base of the capacitive level sensor of the interface between media through the holes for the fasteners of the sensor housing.

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.
