Abstract: A differential pressure sensor module includes a base having a pair of process fluid pressure inlets and defining a sensor chamber having a sensor chamber inlet. A differential pressure sensor is disposed within the sensor chamber and has an inlet configured to receive a first pressure and provide a signal indicative of a difference between the first pressure and a sensor chamber pressure external to the differential pressure sensor within the sensor chamber. A pair of isolation diaphragms are provided in substantially the same plane, with each isolation diaphragm sealing a respective process fluid pressure inlet. A first fluid passageway is operably coupled to one of the isolation diaphragms and the inlet of the differential pressure sensor. A second fluid passageway is operably coupled to the other of the isolation diaphragms and to the sensor chamber inlet. An overpressure protection feature is operably coupled to the sensor chamber, the first fluid passageway and the second fluid passageway.

Abstract: A method of joining a brittle material to a component is provided. The method includes depositing a metallization layer on a surface of the brittle material. A layer of joining material is applied between the brittle material and the component, such that the component and the brittle material define an interface area. The metallization layer and the joining material layer extends beyond the interface area.
