Abstract

A pressure measurement assembly is provided. The assembly includes a pressure sensor mount having an aperture therethrough. A pressure sensor passes through and is mounted to the aperture. The pressure sensor has an electrical characteristic that varies with applied pressure. An isolator plug is configured to be exposed to a process fluid. The isolator plug has an isolation diaphragm disposed to contact the process fluid. A passageway is fluidically coupled to the isolation diaphragm to convey process fluid pressure from the isolation diaphragm to the pressure sensor through an incompressible fluid. The pressure sensor mount is coupled to the isolator plug and has a non-circular shape when viewed along an axis of the aperture.
