Abstract
Official abstract text for this publication.
A co-planar differential pressure sensor module is provided. The module includes a base having a pair of recesses. A pair of pedestals is also provided where each pedestal is disposed in a respective recess and is coupled to a respective isolation diaphragm. A differential pressure sensor has a sensing diaphragm and a pair of pressure sensing ports. Each port of the differential pressure sensor is fluidically coupled to a respective isolation diaphragm by a fill fluid. The module also includes circuitry coupled to the differential pressure sensor to measure an electrical characteristic of the sensor that varies with differential pressure. The base is constructed from a material that is suitable for submersion in seawater. A method of constructing a co-planar differential pressure sensor module is also provided. In another embodiment, a pressure sensor module is provided. The pressure sensor module includes a base having a recess. A pedestal is disposed in the recess and is coupled to an isolation diaphragm. A pressure sensor having a sensing diaphragm and a pressure sensing port is fluidically coupled to the isolation diaphragm by a fill fluid. Circuitry is coupled to the pressure sensor to measure an electrical characteristic of the sensor that varies with pressure. The base is constructed from a material that is suitable for submersion in seawater.
