ABSTRACT:
A pressure module includes a sensor assembly with tubes extending from a pressure sensor to fluid isolator members. The pressure sensor is contained in a cavity in a module housing. The module housing includes support members joined by joints to the fluid isolator members to provide barriers to leakage of process fluids into the cavity. Threaded process inlets on a bottom outside surface of the module housing couple the process fluids to the fluid isolator members through process passageways in the module housing.
