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

• Vacuums in pneumatic conveying lines

• Positive pressure in compressed air headers

• Corrosive ambient environments

DESCRIPTIONAPPLICATIONS

The Series SGY & SGZ 2.5˝ 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 congurations. 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.
