  • Pressure sensing apparatus having pressure pulse dampener
    Patent number: 6681636
    Abstract: An apparatus and method for pressure sensing includes a Bourdon tube connected to a source of fluid pressure for sensing pressure changes therein, the Bourdon tube containing a pressure sensitive medium, a socket having a bore therethrough and positioned to fluidly connect the Bourdon tube with the source of pressure, a diaphragm positioned in the bore between the Bourdon tube and the source of pressure so as to isolate the pressure sensitive medium from the fluid whose pressure is sensed, and a dampener positioned between the diaphragm and the Bourdon tube, the dampener having a porous metallic body effective for substantially dampening transmission of a pressure pulse from the source of pressure to the pressure sensitive medium.
