To combat hostile environments,
this general service gauge is
corrosion, weather, and dust
resistant. Mounting versatility,
PGS-25L-160, shown
actual size.
excellent readability, and sustained
accuracy make this stainless steel
design a gauge leader. It can be
stem, surface, or flush mounted.
Sustained accuracy and excellent
readability are especially important
to users of the OMEGA® general
service gauge line. Meeting the
requirements of many industrial
applications, general service gauges
can be used on steam boilers or
other pressurized vessels; on pumps
and compressors; on many types of
industrial machinery; in the chemical,
petrochemical, and allied process
industries; in power plants; and in
pulp and paper mills.
The pressure gauge actuation
system in the OMEGA® general
service gauge line is the standard
316 SS Bourdon tube system, which
is engineered to precise tolerances
for repeatability and consistent
response to pressure fluctuations.

Warning: To prevent misapplication, all
gauge components should be chosen
with an eye to the media and ambient
operating conditions to which they will
be exposed. Improper application
can be detrimental to the gauge,
causing failure and possible personal
injury and property damage.

back connection, 0/160 psi range.
⁄2"
Insert range code from table below. Comes complete with operator’s manual.
Pressure Range: Select a gauge
with a full scale pressure range
of approximately twice the normal
operating pressure. The maximum
operating pressure should not
exceed approximately 75% of the
full scale range. Failure to select a
gauge range within these criteria
may ultimately result in fatigue
failure of the Bourdon tube.
Oil-Filled Gauges Also Available:
Type S gauges are available on
special order filled with silicone oil.
The silicone oil is used to dampen
the internal movement of the gauge
when it is installed on vibrating
equipment. The oil has an operating
range of -40 to 66°C (-40 to 150°F).
The maximum storage temperature
of the gauge is 82°C (180°F).
To Order: Add suffix “F” to
model number for an additional
cost for 63 mm (21⁄2") gauges or an
additional cost for 89 mm
(31⁄2") gauges.
