Description
The Murphy PT167EX is a pressure
Swichgage instrument connected to a
threaded pressure diaphragm housing. The
Swichgage instrument is enclosed in an
explosion-proof case and is CSA rated for
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.
Applications
Applications include highly viscous liquids
such as crude oil on lead line applications.
Other applications have included asphalt,
sludge, abrasive materials, etc.
