Class I, Division 1, Groups C and D.*

A Swichgage instrument is a pressure indi- cating gage with adjustable low and high pressure limit switches. When the gage pointer touches the low or high limit switch- es, an electrical circuit is completed which can operate alarms and/or shut down equipment.

The 2 NPT, sealed-diaphragm housing is attached directly to the Swichgage connec- tion. The diaphragm housing is filled with a silicone fluid so that pressure against the diaphragm causes the Swichgage instrument to respond. The housing seals the Swichgage sensing element from the medium being measured.
