General information about diaphragm seals

Diaphragm seals are used in pressure measurements when the measuring instrument must be protected from contact with the medium. Diaphragm seals can be used in conjunction with Bourdon tube pressure gauges, pressure switches, transmitters and differential pressure transmitters. They can be made of a wide variety of materials, depending on the type of medium or intended use. The diaphragm seal separates the gauge from the medium and, by filling the system with a pressure-transmitting fluid, ensures virtually instantaneous transmission of pressure to the gauge. We offer a wide range of diaphragm seals and accessories for diverse applications.
