The liquid-filled model 213.53 Bourdon tube pressure gauge is constructed with a case from stainless steel and wetted parts from copper alloy.
The model 213.53 meets the requirements of the international industry standard EN 837-1 for Bourdon tube pressure gauges.
Due to the liquid filling in the case, the pressure element and movement are efficiently damped. Therefore, these instruments are particularly to measuring points with high dynamic loads, such as fast load cycles or vibrations.
The cases of the model 213.53 are available in nominal sizes of 50, 63, and 100 mm and IP65 ingress protection. With an accuracy of up to class 1.0, this pressure gauge is suitable for a wide range of applications in industry.
For mounting in control panels, the pressure gauges with a back mount process connection can be fitted with a mounting flange or with a triangular bezel and mounting bracket.
- For measuring points high dynamic pressure loads and vibrations
- Foe gaseous and liquid media that are not highly viscous or crystallising and will not attack copper alloy parts
- Compressors, shipbuilding
- Vibration and shock-resistant
- Especially robust design
- Type approval for the shipbuilding industry
- Scale ranges up to 0…1,000 bar
