Description:
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 internati-onal 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 instru-ments are particularly suited 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 fulfil IP65 ingress protection. With an accuracy of up to class 1.0, this pressure gauge is suitab-le 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.
Pressure limitation
- NS 50, 63: Steady: 3/4 x full scale value
- Fluctuating: 2/3 x full scale value
- Short time: Full scale value
- NS 100: Steady: Full scale value
- Fluctuating: 0.9 x full scale value
- Short time: 1.3 x full scale value
Temperature effectWhen the temperature of the measuring system deviates from the reference temperature (+20 °C): max. ±0.4 %/10 K of the span
Ingress protection per IEC/EN 60529IP65
