CPC classification number: G01D11/245

Abstract: A sensor for operating in an environment subjected to corrosive gases or liquids under pressure, including a housing inside which are installed: a sensing portion, at least one wire electrically connected to the sensing portion, and a seal for sealing the connection between the sensing portion and the at least one wire, with at least one through-hole receiving a portion of the at least one wire. The sensor further including a compressor installed inside the housing, movable with respect to the housing and adapted to contact the seal in order to compress. The seal is made from a single material that is softer than the material constituting the housing. Upon displacement of the compressor, the seal is deformed until the creation of a compression force exerted by the seal onto the portion of the at least one wire, prevents any passage of corrosive gases or liquids between the seal therebetween.
