4 Inch polycarbonate case pressure gauges with diaphragm seal


Brief :

Diaphragm pressure gauge, is composed of all-stainless steel case gauge and diaphragm body. It is applicable for oil refineries, chemical plants and many other industrial areas. It particularly applies to a corrosive environment.

for diaphragm pressure gauge, we also havenormal type diaphragm pressure gauge.


Application & Features:

• Field liquid-fillable, phenolic solid front blowout back safety case

• ±0.5% accuracy 
• Stainless steel full rotary movement for longer life 
• Micrometer pointer for ease in calibration
• Under and overload stops 
• 316L stainless steel, brass or Monel® wetted parts
• Restrictor screws standard on dual scale (optional on single scale gauges)
• Used where operator safety is a must

• Ideally suited for process, chemical and petroleum industries 
• Highly corrosive media
