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.

Abstract: The invention relates to an electrical transportation wire made of aluminum alloy comprising aluminum, zirconium and unavoidable impurities, characterized in that said alloy comprises at least 80 parts by weight of zirconium in the form of precipitates (Al3Zr) per 100 parts by weight of zirconium in said aluminum alloy.

Abstract: A composite material is provided having functionalized carbon nanotubes and a metal matrix. It is obtained by a process including dispersing functionalized carbon nanotubes or a mixture of functionalized carbon nanotubes and of at least one metal, in an open-pore or semi-open-pore metal foam, in order to form a composite structure, and compacting the composite structure obtained in the preceding stage in order to form the composite material in the form of a solid mass.

Abstract: A process is provided for manufacturing a composite material with functionalized carbon nanotubes and a metal matrix. The arrangement also includes manufacturing an elongated electrically conductive element, and an electrical cable with such an elongated electrically conductive element.
