COVER FOR CHANNEL SENSOR Russian patent published in 2017 - IPC G01N27/407 G01D11/24 

FIELD: measuring equipment.

SUBSTANCE: cover (1) for the channel sensor comprises: an outer envelope surface (3) connected to a seal (4) that protrudes from the outer enveloping surface (3) and surrounds it around the perimeter; a channel (2) with walls (8, 9) and with side walls, passing through the cover (1); a front surface connected to the outer enveloping surface (3) and to the walls (8, 9) of the channel (2). Herewith the channel (2) comprises a guide support extending along its side wall, and the cover (1) comprises an opening in the front surface, which provides an input for the circuit board into the channel (2). The guide support and the opening in the front surface are configured to substantially prevent the play of the circuit board passing through the channel (2). The seal (4) contains a lip (5). The seal (4), the lip (5), the outer enveloping surface (3) and the cover (1) form a monoblock. The group of inventions also relates to a channel sensor comprising a tubular casing, a circuit board and the said cover (1) mounted within the casing.

EFFECT: group of inventions provides an impenetrability of the channel sensor for fluids, its durability and the ability to measure humidity in a wide range.
