These differential pressure gauges are made of highly corrosion-resistant stainless steel and feature an all-metal, all-welded media chamber to ensure long-term leak tightness (no elastomer sealing elements). A high overload safety is achieved by the all-metal construction and the close-fitting design of the pressure measuring diaphragm. With its high-grade stainless steel construction and robust design this pressure gauge is geared to chemical and process engineering applications. It is suitable for gaseous or liquid media, also in aggressive ambience.

Applications
■ For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive ambience
■ Monitoring and control of pumps
■ Filter monitoring
■ Level measurement in closed tanks 

Special features
■ Differential pressure measuring ranges from 0 … 16 mbar
■ High working pressure (static pressure) up to 40 bar
■ High overload safety up to 40 bar
■ All welded media chamber
■ Option: Low-temperature version down to an ambient temperature of -70 °C (-94 °F)
