  • Product Details


Increased safety requirements for personal protection with solid baffle wall designed.

With liquid-filled case for applications with high dynamic pressure loads or vibrations.

For gaseous and liquid aggressive media that are not highly viscous or crystallizing, also in aggressive ambience.

Measure the pressure of medium in technological process which has higher requirements of corrosion-proof and anti-vibration.

Process industry: widely used in oil industry, chemical/petrol-chemical industry, chemical fiber industry, metallurgical industry, power station, mining, on- and offshore, environmental technology, machine building and general plant construction and so on.


Safety version with safety explosion-proof layer and safety pressure relief back cover.

The design is reasonable, the craft is exquisite.

All stainless steel construction.

Excellent load-cycle stability and shock resistance.

Pressure range can up to 0-1000bar.
