US Patent 7421902 Fluid pressure sensing method and apparatus

A method and apparatus for producing a circuit carrier for mounting components of a pressure sensing circuit, circuit carrier formed thereby, an apparatus for housing a pressure sensor circuit carrier to form a pressure sensing apparatus and a pressure sensing system using the pressure sensing apparatus and a coupler for coupling the pressure sensing apparatus to a pressurized system. A housing has provisions for aligning and urging a circuit carrier to sealingly position a pressure sensor adjacent an opening in a wall extending through of housing. The wall defines a pressure sensing chamber operable to cooperate with a pressure coupler having a profile that sealingly engages the wall.
