摘要： A pressure sensor (40) includes a diaphragm assembly (54A) with a pair of diaphragms (58A, 60A) joined together along a rim and having spaced apart centers to form a cavity (62A) between them. A pressure input (50A) applies a pressurized fluid to external surfaces of the diaphragms. The diaphragm assembly (54A) is connected to a mounting block along a tab (82A) leaving the remainder of the diaphragm (54A) free from solid mounting. Deflection of the diaphragm assembly (54A) is sensed and is related to applied pressure.

摘要： Sensor circuitry (60) for sensing changes in capacitance of separate sensor portions (19, 20) wherein in each of the sensor portions (19, 20) a separate plate (20, 22 or 25, 33) will deflect in response to changes in parameter, for example changes in pressure, to thereby provide an output that relates to differential pressure. The specific example is in connection with sensor portions (19, 20) which are fluid filled and in fluid communication with each other so that a deflection of a plate (20, 25) on one of the sensor portions (20) cause an opposite deflection of a plate (22, 23) on the other sensor portion (19). The circuitry (60) provides a stable output regardless of some variation in sensor characteristics. Temperature induced variations in the dielectric constant and density of the fluid filling the sensor portions may all be compensated for in the circuitry. Preferably CMOS logic devices (72) that provide a signal which exhibits a direct relationship to capacitive loading are used. The signal is sensed to modify the voltage applied to the CMOS device (72) to achieve a desired relationship. The voltage or current output from the capacitors (19, 20) indicates the capacitive values of the sensor (19, 20).

摘要： A pressure sensing cell construction (10) comprises a pair of plates (42, 43) which are joined together around the periphery, to form a first chamber (45). A second chamber (52), preferably identically constructed to the first chamber (45) with a second pair of plates (46, 48) is connected to the first chamber (45) through a conduit (47). The chambers (45, 52) and the conduit (47) are filled with non compressible liquid, so that when pressure acts on the outer surfaces of the plates (42, 43, 46, 48), at least one plate deflects and the liquid in one chamber (45) will tend to be squeezed out into the other chamber (47), and by measuring the spacing between the plates (42, 43) the pressure sensed can be determined. The plates (42, 43) preferably are made of a brittle material so that pressures can be determined with high accuracy. The plates (42, 43, or 46, 48) forming the chamber (45 or 47) subjected to the higher pressure will contact each other as a positive stop to limit the amount of deflection of the plates forming the other chamber (45 or 47) as the fluid causes such other chamber to expand under high overpressures on the plates of the chamber subjected to higher pressure. Thus, the device will withstand this high overpressure without damage, even though it is constructed of brittle materials.

摘要： Une construction (10) de cellule de détection de pression comprend une paire de plaques (42, 43) unies à leur périphérie de façon à former une première cavité (45). Une deuxième cavité (52), formée de préférence de façon identique à la première cavité (45) par une deuxième paire de plaques (46, 48), est connectée à la première cavité (45) par un conduit (47). Les cavités (45, 52) et le conduit (47) sont remplis d'un liquide incompressible, de sorte que lorsqu'une pression s'exerce sur les surfaces extérieures des plaques (42, 43, 46, 48) au moins une plaque fléchit, et le liquide tendra à être pressé vers l'autre cavité (47). En mesurant l'écart entre les plaques (42, 43) il est possible de déterminer la pression captée. Les plaques (42, 43) sont faites de préférence en un matériau friable pour permettre de déterminer les pressions avec une très grande précision. Lorsque les plaques (42, 43 ou 46, 48) formant une des cavités (45 ou 47) sont soumises à une pression élevée, elles se touchent arrêtant ainsi de façon positive l'extension du fléchissement des plaques formant l'autre cavité (45 ou 47) lorsque le fluide provoque l'expansion de cette autre cavité sous l'effet des pressions excessives s'exerçant sur les plaques de la première cavité soumise à une pression élevée. Le dispositif peut ainsi résister sans subir des dommages à cette pression excessive, en dépit du fait qu'il est construit en matériaux friables.
