A sealing device (10) comprising a first sealing element (12) having a housing (18) with an internal chamber (26) therein and a second sealing element (14) having a shaft (34). When the first (12) and second sealing elements (14) are connected, the shaft (34) of the second sealing element (14) extends into the internal chamber (26) of the first sealing element (12) through an opening in its housing. According to an important aspect of the invention, the first sealing element (12) comprises a pressure sensor (46) connected to the internal chamber (26) for sensing a pressure in the internal chamber (26); and a transmitter (48) for receiving a signal indicative of the pressure in the internal chamber and for transmitting the signal to a monitoring station.
L'invention concerne un dispositif (10) d'étanchéité comprenant un premier élément (12) d'étanchéité comprenant un logement (18) avec une chambre interne (26) dedans et un second élément (14) d'étanchéité comprenant un arbre (34). Lorsque le premier (12) et le second élément (14) d'étanchéité sont reliés, l'arbre (34) du second élément (14) d'étanchéité s'étend dans la chambre interne (26) du premier élément (12) d'étanchéité au travers d'une ouverture dans son logement. Selon un aspect important de l'invention, le premier élément (12) d'étanchéité comprend un capteur de pression (46) relié à la chambre interne (26) pour détecter une pression dans la chambre interne (26); et un émetteur-récepteur (48) pour recevoir un signal indicatif de la pression dans la chambre interne et pour transmettre le signal à une station de surveillance.
