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.

Abstract: A pressure sensor capsule includes a capsule body, an isolator, a pressure sensor, and a fluid fill pathway. The capsule body defines a process chamber. The isolator is supported by the capsule body and is exposed to the process chamber. The pressure sensor produces a sensor output that is indicative of a pressure within an interior chamber, which is isolated from the process chamber by the isolator. The fluid fill pathway extends from the process chamber to the interior chamber.

Abstract: A pressure sensor assembly for use in sensing a pressure of a process fluid in a high temperature environment includes an elongate sensor housing configured to be exposed to the process fluid and having a cavity formed therein. A pressure sensor is positioned in the cavity of the elongate sensor housing. The pressure sensor has at least one diaphragm that deflects in response to applied pressure and includes an electrical component having an electrical property which changes as a function of deflection of the at least one diaphragm which is indicative of applied pressure. A flexible membrane in contact with the at least one diaphragm is disposed to seal at least a portion of the cavity of the sensor housing from the process fluid and flexes in response to pressure applied by the process fluid to thereby cause deflection of the at least one diaphragm.
