The sensor module includes a diaphragm having a first side and a second side. The first side is configured to receive a first pressure by the first pressure port, and the second side is adapted to receive a second pressure by the second pressure port.

Abstract: Certain implementations of the disclosed technology may include systems, methods, and sealed transducer assembly with a pressure relief vent. In certain implementations, a transducer assembly is provided having a vent bore and a rupturable membrane sealing the vent bore. The vent bore may extend from an internal portion of the transducer assembly to an external portion of the transducer assembly. The rupturable membrane is configured to maintain a seal within the internal portion of the transducer assembly for a first range of a pressure differential between the internal portion of the transducer assembly and the external portion of the transducer assembly, and rupture and vent pressure through the vent bore when the pressure differential exceeds the first range.

Abstract: Exemplary embodiments of the present invention provide a differential pressure transducer that comprises first and second diaphragms of different configurations, i.e., different diameters and/or thicknesses. The pressure transducer provides more versatility over prior art designs as the diaphragms can be of different configurations yet still maintain substantially similar back pressures. Therefore, the errors commonly associated with back pressures are eliminated because the back pressures from the diaphragms ultimately cancel out in the sensor's differential pressure measurement.

Abstract: A tunable pressure transducer assembly that comprises a sensing element disposed within a housing, wherein the sensing element is adapted to output a signal substantially indicative of an applied pressure, and a filter assembly also disposed within the housing. The filter assembly comprises a cap and a tube, wherein the cap is spaced from the sensing element within the housing such that it encloses a set volume around the sensing element, and wherein the tube controls access of the applied pressure to the set volume. The filter assembly is operative to substantially reduce high frequency pressure ripples and allow static and quasi-static pressures to pass through to the sensing element, and may be manipulated to tune the pressure transducer assembly to achieve a desired dampening frequency. The filter assembly therefore enables one pressure transducer assembly outline to accurately measure pressure in various systems.

Abstract: It is an object of the present invention to provide a pressure transducer having a header wherein the header is comprised of a first section and a second section that are offset from each other. Each first and second section has a flexible diaphragm adapted to receive a first and second pressure, respectively. A central channel connects the diaphragms and a pressure sensor, located within the central channel, communicates with the channel and produces an output equal to the difference between the first and second pressures. The resultant device is a low differential pressure transducer which enables one to bring leads from the sensor out while having diaphragms of substantially the same size and diameter, therefore enabling the diaphragms to exhibit the same back pressure and be equally compliant.
