LIQUID-FILLABLE INDUSTRIAL PRESSURE GAUGES
OMEGA’s PGM Series gauges
are suitable for corrosive processing
environments in chemical,
petrochemical refining, power, marine,
food and pharmaceutical applications.
The PGM Series comes in a 63 mm
(2.5") or 100 mm (4") case, features
all stainless steel construction, and is
environmentally protected
to NEMA 4
(IP65) standards.
The PGM Series can also be liquidfilled in the field. Liquid-filled pressure
gauges provide users with a number
of advantages in certain applications.
They are ideal for equipment with
excessive vibration and pulsation, such
as pumps, compressors, and machine
tools. The liquid fill minimizes the
effects of these severe environments,
protects the gauge internals, and
provides continuous lubrication in the
mechanism, adding up to extended
service life. Liquid filling also provides
greater protection of the gauge
internals from corrosive atmospheres.
Gauges can be filled with a variety of
fluids, including glycerin, mineral oil,
and silicone oil.
