Abstract
A remote diaphragm assembly, for use in the process control industry, is disclosed which can be quickly assembled and disassembled by press-fitting a diaphragm housing and an adapter housing together. The diaphragm housing includes a flexible diaphragm and a first retention ring receiving portion. The adapter housing is configured to place the flexible diaphragm in fluid communication with a process fluid in a vessel and includes a second retention ring receiving portion. The first and second retention ring receiving portions align to form a retention ring cavity. A retention ring is positioned within the retention ring cavity such that portions of the retention ring occupy the first and second retention ring receiving portions to couple the diaphragm housing to the adapter housing. Also disclosed is a method for assembling the above-described remote diaphragm assembly. The method includes securing a retention ring to either the first or the second retention ring receiving portions and press fitting the diaphragm housing and the adapter housing together to couple the diaphragm housing to the adapter housing.
