Diaphragm Seal Assemblies (CAP SCREWS)

CAP SCREWS|Ashcroft's diaphragm seals are designed for use with pressure gauges, pressure switches, pressure transducers or pressure transmitters on process applications where (1) process element materials capable of withstanding corrosive effects of certain fluids are not available (2) the process fluid being measured would normally clog the pressure measuring device or (3) the process fluid in the measuring element might freeze due to changes in ambient temperatures. A diaphragm assembly fabricated of materials that will withstand various corrosive media encountered, separates the measuring element from the process fluid. Since the space between the diaphragm and the measuring element is solidly filled with liquid, any movement of the diaphragm, caused by a change in the process pressure, will be indicated by the instrument.
