Abstract: A pressure transmitter includes a housing and a pressure sensor having an electrical characteristic that varies with applied pressure. The pressure sensor is configured to generate a sensor signal indicative of process fluid pressure. A transmitter isolation diaphragm is configured to couple to a process barrier seal to convey pressure to the pressure sensor. A flange is coupled to the transmitter isolation diaphragm. The flange includes at least one gas pathway extending inwardly from an outer diameter of the transmitter isolation diaphragm. Electronics are coupled to the pressure sensor to receive the sensor signal and to generate an output indicative of the pressure.

Abstract: An electronics package includes a platform and a board mounted to the platform, the board having electronics mounted thereon. A feedthrough pin passes through and is hermetically sealed to a feedthrough body and is wire bonded to the board. A cover is bonded to and surrounds the exterior surface of the feedthrough body to produce a hermetically sealed chamber that houses the platform and the board.
