  • Process pressure transmitter with seal having diamond like carbon coating
    Patent number: 10514311
    Abstract: A process pressure transmitter system includes a process pressure transmitter housing, a process pressure sensor in the process pressure transmitter housing, a flange face in the process pressure transmitter housing and an isolation diaphragm on the flange face. A first capillary passageway carries a first fill fluid from the isolation diaphragm to the process pressure sensor. A process seal diaphragm couples to a process fluid of the industrial process. A second capillary passageway carries a second fill fluid from the process seal diaphragm to the isolation diaphragm. A diamond like carbon (DLC) coating coats the process seal diaphragm.
