Description
The mechanical model 212.20 bourdon tube pressure gauge is constructed with a case from stainless steel and witted parts form copper alloy.
The model 212.10 meets the requirements of the international industry standard EN 837-1 for Bourdon tube pressure gauges.
Frequent measuring points are found in the machne building, plant construction and building service industries. The model 212.20 can also be used in refrigeration applications.
The modular design enables a multitude of combination of process connections, nominal sizes scale ranges. This high varience enambles 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.
