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.

The conventional geared 
movement shown below is typical 
of those used by most 
manufacturers of commercial 
pressure gauges.

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.
