212.20 WIKA industrial pressure gauge with bourdon tube

Description

212.20 WIKA industrial pressure gauge with bourdon tube is used for pressure measurement of gaseous and liquid media.

The mechanical model 212.20 Bourdon Pressure Gauge is made of a stainless steel casing and copper alloy wetted parts.

The 212.20 meets the requirements of the international industry standard EN 837-1 for Bourdon tube manometers.

Common measurement sites are found in the mechanical engineering, plant construction and building services industries. Model 212.20 can also be used in refrigeration applications.

The enclosures are available in nominal sizes of 100 and 160 mm and meet IP54 ingress protection. With an accuracy class of 1.0, this pressure gauge is suitable for the process industry.

The modular design allows for a multitude of combinations of process connections, nominal sizes and scales of scope. This high variance allows universal use of the instrument in the industrial sector.

For mounting on control panels, pressure gauges can be equipped with a mounting flange or with a triangular plate and mounting bracket.
