SERIES SGY & SGZ
2.5˝ INDUSTRIAL PRESSURE GAGES
1.5% FS Accuracy, 316 SS or Brass Wetted Parts, Dual Psi/Bar x100 kPa Scales
PRESSURE
SGZ bottom
The Series SGY & SGZ 2˝ Industrial Pressure Gages have dual psi and bar (x100
kPa) scales with ±1.5% full-scale accuracy. The Series SGZ and SGY gages are
designed with 304 SS housings and the SGZ is designed with 316 SS wetted parts
for excellent chemical compatibility or SGY brass wetted parts for compatible gases.
These gages cover a wide variety of ranges in either bottom or back connection
congurations. Series SGZ gages employ an easy-open breather plug on top, which
allows liquid lled units to breathe, relieving any built up internal pressures. Plug easily
pops open and does not need to be entirely removed or cut like a typical gages’ rubber
plug grommet.
FEATURES/BENEFITS
• Stainless steel housing and
wetted parts to resist ambient
corrosion for longer service
life in harsh environments
• Higher accuracy gage for
value-sensitive applications
requiring more precise
measurement and where
vibration is a concern
• Optional sliding pointer
clearly mark to make
visible critical ranges
and high and low points
• Liquid llable gage with easy open
breather plug provides smoother
damped movement of pointer
• Back or bottom mounting and
compact size provides for mounting
with dimensional limitations
SGZ back with
accessory pointers
SGY bottom
APPLICATIONS
• Vacuums in pneumatic conveying lines
• Positive pressure in compressed air headers
• Corrosive ambient environments
