Abstract: A process pressure transmitter system includes a process pressure transmitter housing and a process pressure sensor in the process pressure transmitter housing. A metal flange is configured to mount to a process vessel which carries a process fluid. An isolation diaphragm attaches to the metal flange and is exposed to the process fluid through an opening in the process vessel. The isolation diaphragm comprises a polymer diaphragm bonded to a metal face of the metal flange. A capillary passageway carries a fill fluid from the isolation diaphragm to thereby convey a process pressure to the pressure sensor.

Abstract: A process diaphragm seal includes a seal body, a diaphragm, and a ring member. The seal body includes a flange that surrounds a cavity. The diaphragm includes an active portion that extends over the cavity and a peripheral portion that surrounds the active portion. The ring member clamps the peripheral portion of the diaphragm to an outer wall of the flange through an interference fit between an inner wall of the ring member and the outer wall of the flange. A seal is formed between the peripheral portion of the diaphragm and the outer wall of the flange.

Abstract: The present disclosure is provided with a measuring element (M) and a measuring device. The measuring element includes a base body, a diaphragm and a permeation resistant layer, the diaphragm is fixedly connected to the base body, with a sealed cavity being defined between the diaphragm and the base body. The permeation resistant layer is arranged on an inner side surface, facing the sealed cavity, of the diaphragm, and extended continuously on the inner side surface of the diaphragm at least beyond a connection region of the diaphragm with the base body. The measuring device includes the measuring element (M).
