Abstract: A press-fit remote diaphragm assembly includes a diaphragm member and a mounting portion which can be press-fit assembled by hand and without the use of tools. The diaphragm member includes a flexible diaphragm and a first press-fit member receiving portion. The mounting portion includes a second press-fit member receiving portion. The first and second press-fit member receiving portions align to form a press-fit member cavity which contains a press-fit member. The press-fit member engages the first and second press-fit member receiving portions to couple the diaphragm member to the mounting portion.

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.

Abstract: A process diaphragm seal includes a diaphragm seal body having a seal body ring portion surrounding a cavity and a diaphragm having a diaphragm ring portion. The diaphragm ring portion includes a diaphragm ring outer portion that corresponds to a seal body ring outer portion of the seal body ring portion and a diaphragm ring inner portion that corresponds to a seal body ring inner portion of the seal body ring portion. A first weld of the diaphragm ring outer portion to the seal body ring outer portion forms a closed path around the seal body ring portion. A second weld of the diaphragm ring inner portion to the seal body ring inner portion forms a closed path around the cavity. Between the first and second welds a diaphragm ring back surface is in substantially continuous contact with the seal body ring portion.
