(FR) TRANSMETTEUR DE PRESSION DE PROCESSUS AVEC JOINT EN POLYMÈRE
Abstract:
(EN) A process pressure transmitter system includes a process pressure transmitter housing (14) and a process pressure sensor (28) in the process pressure transmitter housing (14). A metal flange (17) is configured to mount to a process vessel (10) which carries a process fluid (16). An isolation diaphragm (25) attaches to the metal flange (17) and is exposed to the process fluid (16) through an opening in the process vessel (10). The isolation diaphragm (25)comprises a polymer diaphragm bonded to a metal face of the metal flange (17). A capillary passageway carries a fill fluid from the isolation diaphragm to thereby convey a process pressure to the pressure sensor (28).
(FR) L'invention concerne un système transmetteur de pression de processus qui comprend un boîtier de transmetteur de pression de processus (14) et un capteur de pression de processus (28) dans le boîtier de transmetteur de pression de processus (14). Une bride métallique (17) est configurée pour être montée sur une cuve à processus (10) qui transporte un fluide de processus (16). Une membrane d'isolation (25) est fixée à la bride métallique (17) et elle est exposée au fluide de processus (16) à travers une ouverture dans la cuve à processus (10). La membrane d'isolation (25) comprend une membrane en polymère liée à une face métallique de la bride métallique (17). Un passage capillaire transporte un fluide de remplissage provenant de la membrane d'isolation afin de transférer ainsi une pression de processus au capteur de pression (28).
