Diaphragm Sealed Gauges (Series 600)Applications
Diaphragm sealed gauges are traditionally used when a standard measuring instrument should not be exposed to the process pressure directly, like viscous, corrosive gases and liquid media in corrosive environment. Diaphragm Sealed gauges typically protect the measuring instruments from one or more damaging aspects of the process media.
