Wika 131-11 Bourdon tube pressure gauge

Due to its modular architecture, this instrument (Wika 131-11) can be configured with various process connections, nominal sizes, and scale ranges, making it ideal for different industrial applications.

product overview

The Bourdon tube pressure gauge model 131-11 features stainless steel casing and wetted sections.

On gas cylinders, the device is widely employed as a failure alert indication. The pressure gauge is suitable for machine-building and plant-construction applications due to its small size and affordable price.

The instrument may be used with liquid and gaseous media even in hostile conditions since it is made of sturdy stainless steel elements.

The pressure gauges can be equipped with a surface mounting flange or a mounting bracket and triangular profile ring for placement in control panels.

Applications

1-aggressive environments also apply to gaseous and liquid-aggressive media that are not excessively viscous or crystallizing.
2-Building machines and constructing a plant in general.
3-indication of a gas cylinder failure alert.
4-Applications for clean, dry air (CDA).
