摘要： A pressure sensor comprising a housing, a diaphragm wafer, and an isolator configured to absorb lateral stress. The diaphragm wafer includes a fully exposed diaphragm, a fluid contact surface, a sensing element, and a support portion, where the support portion and the contact surface define a cavity. The isolator extends laterally from the support portion to the housing. The pressure sensor is easily drainable, eliminating the buildup of particulates, and the diaphragm can be directly wire-bonded to printed circuit boards, eliminating the need for extensive electrical feedthrough.

摘要： A transducer baseplate includes a base, a protrusion extending from the base along a longitudinal axis, a pair of opposed transducer receptacles defined within the protrusion, and respective pressure plena. The pressure plena are separated by a plenum wall, each plenum being in fluid connection with an area external to the protrusion through a respective pressure line. The pressure lines provide a direct fluid path to their respective receptacles.

摘要： Apparatus and associated methods relate to generating redundant measurement of pseudo differential pressure using two absolute-pressure sensors, each exposed to a different environment. Each of the two absolute-pressure sensors has complementary first and second output nodes. The first output node has a positive relation with and/or response to increasing pressure, while the second output node has a negative relation with and/or response to increasing pressure. A first difference measurement signal is calculated based on a difference between the positive relation output signals of the first and second absolute-pressure sensors. A second difference measurement signal is calculated based on a difference between the negative relation output signals of the first and second absolute-pressure sensors. Both the first and second difference measurement signals are indicative of a pressure difference between the first and second environments. Such redundant measurement of differential pressure can advantageously provide continuous pressure-difference measurement in spite of various component failures.
