Abstract: A metal thin film bonds a semiconductor bonding region of a diaphragm layer to a ceramic bonding region of a high modulus support block. The arrangement isolates a pressure sensing diaphragm from undesired strain, improving sensor accuracy. A passageway through the support block couples the fluid pressure to the sensing diaphragm to deflect it. Capacitive coupling between the diaphragm and a capacitor plate on the support block sense the deflection and provide an output representative of pressure.

Abstract: A co-planar differential pressure sensor module and method of construction thereof is provided which is suitable for submersion in seawater. 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.

Abstract: A remote seal assembly (18, 20) for subsea applications is provided. The assembly (18, 20) includes an upper housing (34, 102) having a fluid coupling (110) for coupling the remote seal to a process fluid pressure measurement device. A lower housing (36, 104) is coupled to the upper housing (34, 102) and has an interface that is configured to mount to a pressure vessel (12). The lower housing (36, 104) also has a process fluid inlet (32). An isolation diaphragm (41, 154) is disposed between the upper and lower housings. At least one of the upper housing (34, 102), lower housing (36, 104) and isolation diaphragm (41, 154) are constructed from a material suitable for immersion in saltwater. In some embodiments, the lower housing (36, 104) has a shoulder (140) disposed about the process fluid inlet (32) and a plurality of self-energizing seals (40, 42) configured to couple the assembly to a venturi flow meter body (12). A subsea process fluid flow measurement system is also provided that includes a pressure transmitter and at least one subsea remote seal assembly.

Abstract: A process control instrument for coupling to a process is attachable to a metal flange. The flange has a first passageway adapted to be filled with process fluid. The process control instrument includes a body having an opening adjacent to the first passageway for receiving process fluid from the first passageway when the process control instrument is attached to the flange. A diaphragm is disposed across the opening for fluid communication with the process fluid. A seal is positionable against the flange to prevent process fluid from leaking past the flange and diaphragm. The seal includes a ring positioned in the opening and coupled to the body, the ring being substantially in contact with the diaphragm along an inner annular shoulder when the body is not attached to the flange (unloaded).

Abstract: A capacitive pressure transmitter is provided. In one aspect, the transmitter includes a capacitive pressure sensor coupled directly to the measured media without any intervening fluid isolation. A filter is preferably used to keep particulates from reaching the measuring diaphragm. In another aspect, a capacitive pressure transmitter is provided with at least one self-contained isolator interposed between a process connection and the capacitive pressure sensor. In both aspects, the capacitive pressure transmitter is relatively small and preferably constructed from materials that facilitate low-cost manufacture.
