Bourdon tube pressure gauge, heavy-duty version

The model PG21HD Bourdon tube pressure gauge is suitable for measuring points with high demands on the measurement accuracy, reproducibility and long-term stability. A multitude of options enables users to adapt the instruments to their specific requirements.

The model PG21HD pressure gauges are based on the proven Bourdon tube measuring system. On pressurisation, the deflection of the Bourdon tube, proportional to the incident pressure, is transmitted to the movement via a link and indicated.

The model PG21HD meets the requirements of the international industry standard EN 837-1 for Bourdon tube pressure gauges.

The instrument complies with the accuracy class 1.0 and is thus suited for a wide range of applications in the machinebuilding and equipment-manufacturing industries. Resistance to shock and vibration is provided due to the glycerine case filling.

The mounting bracket, which is available as an option, enables the panel mounting of pressure gauges with back mount process connection.

The model PG21HD is also available in customer-specific versions, e.g. with individual dial layout.
