    摘要： A sensor includes a housing having a body, a plurality of ports, and a plurality of cavities. The ports include a first port and a second port, and the cavities include a first cavity disposed in the first port and a second cavity disposed in the second port. The sensor includes a first diaphragm disposed in the first port and enclosing the first cavity and a second diaphragm disposed in the second port and enclosing the second cavity. The first diaphragm and the second diaphragm are coplanar with one another in a first plane. The sensor includes a die disposed in the first cavity and having a membrane that is deflectable according to a differential pressure between a first pressure in the first cavity and a second pressure in the second cavity. The die is attached to the housing along a second plane parallel to the first plane.

    摘要： An apparatus, for controlling signal passage, includes a first passageway for a first fluid, a second passageway for a second fluid, and an interposed chamber. A first, movable diaphragm at a first chamber junction and a second, movable diaphragm at a second chamber junction, with a third fluid bound there between and interposed between the first and second passageways. A device varies a volume of the third fluid bound between the diaphragms and thus moves the diaphragms. The diaphragms each have at least one position that permits passage of a pressure signal between the first fluid in the first passageway and the second fluid in the second passageway through the third fluid bound between the diaphragms. The diaphragms each have at least one position that prohibits passage of a pressure signal.

    摘要： A process pressure measuring system includes a transmitter having a first sealed system in which a first outlet couples to a pressure sensor, a first isolator diaphragm assembly, a first capillary passage, and a first isolation fluid. The first isolation fluid couples a first pressure from the first isolator diaphragm to the first outlet and the pressure sensor. A second sealed system includes a second pressure outlet that is coupled to the first isolator diaphragm assembly, a second isolator diaphragm assembly, a second capillary passage and a second isolation fluid. The second isolation fluid is adapted for use in a first temperature range and couples a pressure from the second isolator diaphragm assembly to the second pressure outlet. A third sealed system includes a third pressure outlet that is coupled to the second isolator diaphragm assembly, a third isolator diaphragm assembly, a third capillary passage and a third isolation fluid. The third isolator fluid is adapted for use in a second temperature range and couples a process pressure to the third pressure outlet.

    摘要： A MEMS differential pressure sensing element is provided by two separate silicon dies attached to opposite sides of a silicon or glass spacer. The spacer is hollow. If the spacer is silicon, the dies are preferably attached to the hollow spacer using silicon-to-silicon bonding provided in part by silicon oxide layers. If the spacer is glass, the dies can be attached to the hollow spacer using anodic bonding. Conductive vias extend through the layers and provide electrical connections between Wheatstone bridge circuits formed from piezoresistors in the silicon dies.
