Beschreibung
Zusammenfassung:	4. The invention concerns a sensor (1) for operating in an environment subjected to corrosive gases or liquids under pressure, comprising a housing (2) inside which are installed: - a sensing portion (3), - at least one wire (4) electrically connected to the sensing portion (3), and - a seal (5) for sealing the connection between the sensing portion (3) and the at least one wire (4), with at least one through-hole (6) receiving a portion of the at least one wire (4), the sensor (1) further comprising a compressor (7) installed at least partly inside the housing (2), movable with respect to the housing (2) and adapted to contact the seal (5) in order to compress it, wherein upon displacement of the compressor (7), the seal (5) is deformed until the creation of a compression force exerted by the seal (5) onto said portion of the at least one wire (4), so as to prevent any passage of corrosive gases or liquids between the seal (5) and the at least one wire (4).
