Diaphragm Seals

A diaphragm seal is a flexible membrane that seals and isolates an enclosure. The flexible nature of this seal allows pressure effects to cross the barrier but not the material being contained. Common uses for diaphragm seals are to protect pressure sensors from the process fluid whose pressure is being measured.
A Diaphragm Seal can be mounted to almost all pressure instruments. They are mostly used in combination with pressure (gauge or differential) transmitters, but also in combination with pressure gauges and pressure switches.
