  • Patent number: 8333117
    Abstract: Isolation elements comprise a housing comprising a longitudinal bore formed therein and at least one recess formed in at least one longitudinally extending side of the housing. The at least one recess is in communication with the longitudinal bore. At least one diaphragm is attached proximate a periphery thereof to the housing and seals the at least one recess at the at least one longitudinally extending side of the housing. Sensor assemblies may include an isolation element including a housing and a diaphragm coupled thereto. Methods of forming an isolation element for use with a sensor comprise forming a longitudinal bore in a housing; forming at least one recess in at least one longitudinally extending side of the housing; coupling at least one diaphragm to the housing; and positioning the at least one diaphragm such that a primary direction of displacement of the at least one diaphragm extends into the at least one recess.

  • Patent number: 6131462
    Abstract: A transducer pressure crystal having improved thermal coupling with the environment external to a pressure housing in which the crystal is disposed. A cylindrical major portion of the side wall of the pressure crystal is located immediately adjacent an inner wall of a chamber within the pressure housing, separated therefrom only by dimensional tolerances sufficient to ensure that the crystal is surrounded by pressure-transmitting fluid exposed to pressure from the external environment. The thermal time constant of the transducer for external temperature changes is significantly decreased. The time constant of the transducer for temperature changes in the pressure-transmitting fluid produced by rapid pressure changes is similarly decreased. A thin, electrically insulating element may optionally be disposed between the crystal side wall and the inner wall to preclude electrical grounding of the crystal to the housing.
