  • Filling body for reducing a volume of a pressure measurement chamber
    Patent number: 10969287
    Abstract: The present disclosure relates to a filling body for reducing a volume of a pressure measurement chamber, which is to be filled with a pressure transmitting fluid, surrounding a pressure sensor. The filling body includes a recess for receiving the pressure sensor and has a free-standing base projecting into the recess on which the pressure sensor can be mounted. A filling body base supporting the filling body is provided on a side of the filling body facing away from the recess.

  • Fluid pressure sensor
    Patent number: 10969288
    Abstract: A sensor includes a port body which defines an axial passage for receiving fluid. An electrical connector extends through an opening in the port body near a crimp portion opposite the axial passage and forms an upper seal with the port body. Within the interior of the port body, a support ring and base cover form a cavity which retains a sensing element. The sensing element is exposed to the fluid within the axial passage and determines the pressure. An annular seal is retained by the base cover. The crimp portion of the port body is crimped to provide an upper seal and apply a force on the components within the interior, pinching the annular seal between the sensing element and the base of the port body to create a lower seal.
