Pressure Gauge Model 610.20 and 630.20


As class 0.6 test gauge series, the model 610.20 and 630.20 capsule pressure gauges are suitable for precision measurements in laboratories. They are based upon the proven capsule measuring system. On pressurisation, the expansion of the capsule element, proportional to the incident pressure, is transmitted to the movement and indicated.

The modular design enables a multitude of combinations of case materials, process connections, nominal sizes 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 gages can, depending on the process connection, be fitted with a surface mounting flange or with a triangular bezel and mounting bracket.
