  • Patent number: 11441962
    Abstract: The invention includes differential pressure transducer assembly systems and methods in which headers are configured with header pins that extend perpendicular with respect to an axis of the assembly and through header sidewalls, enabling a compact configuration, ease of assembly, enhanced reliability and/or redundancy. Channels and ports defined in a housing portion of the assembly are configured to enable the use of substantially straight tubing sections for routing main and/or reference pressures to one or more differential sensing elements mounted on the headers. Two or more headers with associated sensing elements can be stacked to provide redundant differential pressure sensing.

  • Patent number: 11433654
    Abstract: This disclosure provides systems and methods for a fluid-filled pressure sensor assembly for higher pressure environments. A fluid-filled pressure sensor assembly may be adapted for coupling to a structure at a mating surface and may include a header; a pressure sensor coupled to the header; a diaphragm coupled to the header and configured for positioning forward of the mating surface so that a fluid region is disposed between the diaphragm and the pressure sensor; a fill hole coupled to the fluid region; a sealing element coupled to the fill hole and configured for positioning forward of the mating surface; and wherein during operation the first pressure applied at the diaphragm is substantially transferred by the fluid in the fluid region and the fill hole to an inner-side of the sealing element and the first pressure is about equivalent to a second pressure applied at an outer-side of the sealing element.

  • Publication number: 20220178778
    Abstract: A reconfigurable pressure transducer assembly having an input tube filter assembly is provided. Multiple small inlet apertures of the transducer housing or input tube filter assembly may be utilized to filter particulate matter from the measurement media/fluid. The resonant frequency and dampening characteristics of the pressure transducer assembly may be configured by the input tube filter assembly such that temporary clogging of a portion of the small inlet apertures does not appreciably affect the resonant frequency and dampening characteristics. The input tube filter assembly includes one or more inserts disposed in an input tube channel, the one or more inserts including one or more apertures of selectable dimensions and extending therethrough from a first end to a second end. The one or more inserts define at least a filter aperture, and the input tube filter assembly is tunable by selection of the selectable dimensions of the one or more inserts.

  • Patent number: 10768068
    Abstract: A pressure scanner assembly having at least one replaceable sensor plate, wherein each of the replaceable sensor plates has at least one pressure sensor adapted to transmit a signal substantially indicative of a sensed pressure condition. A memory chip, which stores correction coefficients for each of the pressure sensor to compensate for thermal errors, may be installed on each of the replaceable sensor plates. The signals from the pressure sensors are multiplexed and may be outputted in analog or digital form. The pressure scanner assemblies described herein have sensor plates that can be interchanged with other sensor plates of the same or different pressure range without disrupting the electronic configuration of the pressure scanner assembly or having to recalibrate and/or update the memory chip installed thereon.
