Applications of the diaphragm pressure gauge
- For measuring points with increased overpressure
- With liquid-filled case for applications with high dynamic pressure loads or vibrations (Model 433.50)
- For gaseous and liquid, aggressive and highly viscous or contaminated media, also in aggressive ambience
- Process industry: Chemical/petro-chemical, power stations, mining, on- and offshore, environmental technology, machine building and general plant construction
Special Features of the diaphragm pressure gauge
- All stainless steel construction
- High overpressure safety
- Process connection thread or open flange
- Wide choice of special materials
- Scale ranges from 0 … 16 mbar
