Pressure Gauge WIKA Model 612.20


DESCRIPTION

The model 612.20 capsule pressure gauge is based upon the proven capsule measuring system. The capsule measuring principle is particulary suitable for low pressure. On pressurisation, the expansionn of the capsule element, proportional to the incident pressure, is transmitted to the movement and indicated.

The case and the bayonet ring are made from stainless steel. The material of the process connection is a copper alloy.

The modular design enables a multitude of combinations of case materials, process connections, nominal size and scale ranges. Due to this high varience, the instrument is suitable for use in a wide range of applications within industry.

For mounting in control panels, the capsule pressure gauges can, depending on the process connection, be fitted with a surface mounting flange or with triangular bezel and mounting bracket.
