The OMEGA
movement represents the design of
the future. Wearing parts have been
reduced to a minimum. The entire
movement is suspended between
2 springs, the Bourdon tube above
and the link below. For the user,
this means greater resistance to
mechanical shock and vibration.
This increased resistance to the
effects of rough usage contributes
to longer gauge life.

GAUGES
The high reliability of the OMEGA®
commercial gauge line is chiefly
attributable to the unique OMEGA®
spring-suspended movement. The
entire movement is suspended
between 2 springs, the Bourdon
tube above and the link below.
Wearing parts have been reduced
to a minimum. Movement parts
are ultrasonically cleaned and
lubricated with silicone oil to ensure
long cycle life. The OMEGA® springsuspended movement is largely
resistant to shock, pulsation, and
vibration. The result is longer gauge
life. The numerous applications for
OMEGA® commercial gauges
include installation on pumps,
portable compressors, industrial
machinery, hydraulic and pneumatic
systems, instrumentation, and
pressurized vessels.
