Solid Front Pressure Gauge WIKA model 232.30

Solid Front Pressure Gauge WIKA model 232.30

Solid front safety gauges are designed to protect users and prevent accidents. The solid front gauge is reinforced at the front, providing a blow-out back safety case design. A solid partition wall between the front of the gauge and the Bourdon tube system will redirect the released energy to the back of the gauge in which the blow-out back of the safety case design redirects any lose parts or media to exit through the back of the gauge. Solid front design gauges have become standard safety equipment at most modern process plants. This type of gauges reduces the risk of getting injured if a gauge is misapplied.

Applications

With liquid-filled case for applications with high dynamic pressure pulsations (add restrictor) or vibration

Suitable for corrosive environments and gaseous or liquid media that will not obstruct the pressure system

Process industry: chemical/petrochemical, power stations, mining, on and offshore, environmental technology, mechanical engineering, and plant construction
