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.
