The mechanical model 212.20 Bourdon tube pressure gauge is constructed with a case from stainless steel and wetted parts from copper alloy. The model 212.20 meets the requirements of the international industry standard EN 837-1 for Bourdon tube pressure gauges. Frequent measuring points are found in the machine building, plant construction and building services industries. The model 212.20 can also be used in refrigeration applications. The cases are available in nominal sizes of 100 and 160 mm and fulfil IP54 ingress protection. With an accuracy class of 1.0, this pressure gauge is suitable for the process industry.
The modular design enables a multitude of combinations of process connections, nominal sizes and scale ranges. This high variance enables universal use of the instrument in the industrial sector. For mounting in control panels, the pressure gauges can be fitted with a mounting flange or with a triangular bezel and mounting bracket.
Applications
- Shut-off and venting of pressure measuring instruments
- Flange connection of instruments with threaded connections to pipelines or vessels
- For aggressive liquids, gases and vapours, also in aggressive environments
- Oil and gas industry, chemical and petrochemical industries, power plants, primary metals
Special Features
- Compact design with low number of potential leakage points reduces overall weight
- Threaded mounting of bonnets not wetted to avoid seizure and leaks
- Smooth valve actuation, even under high pressure, leads to fault-free operation and long service life
- Metal valve seat with leak-tested tightness in accordance with BS6755 / ISO 5208 leakage rate A
- Instrument version for “fugitive emissions” according to TA-Luft and ISO 15848-1
