    摘要: A sensor has an electrical interconnect grown in a cavity between first and second layers that are bonded together. Electrically conductive grain growth material is selectively deposited on at least one of two electrically conductive film interconnect regions that face one another across the cavity. The grain growth material is then grown upon predetermined conditions to form the electrical interconnect between the two interconnect regions. A sensor element deposited in the cavity is electrically coupled between the layers by the interconnect. The grain growth material can be tantalum that is heated after the layers are bonded to grow grains that interconnect the electrically conductive films.

    摘要: A pressure sensor is provided for measuring a pressure difference between two fluids which does not require isolation fluid. The pressure sensor includes a diaphragm support member having an outer periphery and diaphragms coupled thereto. Movement of the diaphragms are the movement of a moveable member. The movement can be sensed to determine the applied differential pressure. The coupling member is joined to the outer periphery with a web. The web is recessed from opposed outwardly facing surfaces of the outer periphery, and first and second diaphragms disposed on opposite sides of the diaphragm support member. Each diaphragm is joined to the outer periphery and to the coupling member.

    摘要: A strain gauge sensor for providing an electrical output responsive to a parameter applied to a substrate. A homogenous thin film circuit is deposited on an insulating layer which is deposited on a substrate of single-crystal material. The thin film circuit includes a strain gauge responsive to strain transferred through the insulating layer from the substrate and resistance trimming networks trimmed by removal of thin film material from the trimming networks to adjust zero and gain. A diaphragm is etched in the substrate to form a pressure sensor. An optional support layer may be added to the sensor for mounting the sensor to a surface.

    摘要: A differential pressure transmitter includes first and second process fluid inlets. A differential pressure sensor is disposed within the transmitter and has first and second sensor inlets. A first isolator diaphragm is located proximate the first process fluid inlet and is operably coupled to the first sensor inlet through a first fill fluid volume. A second isolator diaphragm is located proximate the second process fluid inlet and is operably coupled to the second sensor inlet through a second fill fluid volume. Measurement circuitry is operably coupled to the differential pressure sensor and configured to measure an electrical parameter of the sensor and provide an indication of the measured parameter. A third fluid volume substantially surrounds the differential pressure sensor. The third fluid volume exerts a compressive force on the differential pressure sensor.

    摘要: A deflecting diaphragm differential pressure sensor is formed so all electrical elements and connections from external circuitry to the sensor are isolated from the pressure media. The deflecting, pressure sensing diaphragm is made of a semi-conductor material, having piezoresistors disposed on a surface thereof to form strain gages to sense deflection of the diaphragm. The strain gage resistors are media isolated by a layer that overlies the strain gage resistors. All forms of the invention provide environmental protection for the electrical connections for external circuitry, which are subject to corrosion from the pressure media.
