說明

The mechanical model 212.20 Bourdon tube pressure gauge is constructed with a case from stainless steel. The wetted parts material is copper alloy or stainless steel, depending on the scale range.

WIKA manufactures and qualifies the pressure gauge in accordance with the standards EN 837-1 and ASME B40.100. As a safety function, this instrument has a blow-out device. In the event of a failure, overpressure can escape there.

Applications for this instrument can be 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 [4″] and 160 [6″] and fulfil IP54 ingress protection.

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 profile ring and mounting bracket.
