PRESSURE SEALED HOUSING APPARATUS AND METHODS

摘要

A selectively pressured housing apparatus comprising a body, a wall member, an aperture, and a mounting seat. The body has a chamber therein extending along a first axis, is open at a first axial end and a second axial end, and has a port extending along a second axis transverse to the first axis. The port communicates with the chamber. The wall member is inside of the body and extends transverse to the first axis and parallel to the second axis and divides the chamber into first and second compartments, axially spaced along the first axis. The port communicating with the chamber is in the second compartment. The aperture extends through the wall member and connects the first and second compartments. The mounting seat is on the wall member and extends circumferentially about the aperture for removably and replaceably seating an element with a selected pressure seal to the wall member. According to one preferred embodiment, the first and second compartments are employed for housing process electronics associated with a differential pressure transmitter.
