Differential pressure gauge WIKA

Differential pressure gauge WIKA Model 732.51

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 ambiance.

The optionally available low-temperature version allows the use for temperatures of down to -70 °C (-94 °F). The scale ranges of 0 … 16 mbar to 0 … 25 bar is available to meet the requirements of a wide variety of applications.

Applications

• For gaseous and liquid aggressive media that are not highly viscous or crystallizing, also in the aggressive ambiance
• Monitoring and control of pumps
• Filter monitoring
• Level measurement in closed tanks
