The pressure gauge is of the bourdon tube type, which has a circular formed tubular spring with an oval cross section. The pressure in the system influences the bourdon tube internally so that an increase in pressure tends to straighten it out. The free end of the bourdon tube gives a movement proportional to the internal pressure. The movement is then transferred via the measurement unit to a movement/indicated value on the scale. The pressure gauge has a red adjustable pointer to indicate the maximum allowable pressure.

Pressure gauges with electrical contact in muted or industrial design upon request.
Pressure gauges shall be mounted so that they are easy to read and protected against vibration, heat, cold and high humidity. At high media temperatures water worm pipes shall be used. When pressure fluctuations and vibrations, damping liquid filled pressure gauge should be used.
The cables are labeled with numbers. Electrical installation according to schematic.
