A diaphragm pressure gauge or 'Chemical Seal' is an instrument normally used to measure the pressure of toxic, corrosive, and fibrous media. If a standard pressure gauge were to be used it would be damaged, become clogged, or would have a reduced life expectancy, if allowed to enter the sensitive mechanism and materials within the instrument.
The diaphragm can also be used to measure atmospheric pressure, the pressure within a gas canister, or to measure a vacuum.
It is different from the standard bourdon pressure gauge in that it does not have a small inlet hole and does not allow the process media to enter the pressure gauge.
