SERIES SGP & SGO | 4˝ STAINLESS STEEL SCHAEFFER GAGES
FEATURES/BENEFITS
• Stainless steel housing and wetted parts resist ambient corrosion for
longer service life in harsh environments
• Wetted parts permit use in chemical applications
• High accuracy gage for applications requiring more precise measurement
• Models that support vacuum to higher pressure ranges provide a
selection to meet specic applications
• Specied with high ambient and process temperature ratings mean more
robust uses and longer service-life
APPLICATIONS
• Chemical
• Renery
• Fertilizer
• Petrochemical
• Power
DESCRIPTION
The Series SGP & SGO 4˝ Stainless Steel Schaeffer Gages have dual English/metric
scales with ±1.6% full scale accuracy. The Series SGP gages are designed with 304 SS
housings, a 316L SS chamber and a 316 SS diaphragm for excellent chemical compatibility.
The SGO has a PTFE protected steel diaphragm. Units can withstand ambient temperatures
up to 149°F (65°C) and process temperatures up to 248°F (120°C). Ranges are available
from full vacuum, compound and pressures to 235 in w.c. are available. Micrometer adjustable
pointer allows for re-zeroing gage in eld.
