DESCRIPTION
The model 111.16 and 111.2 have been specifically designed for panel mounting and therefore feature a back mount process connection
The model 111 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 link and indicated.
For easy installation, the plastic cases of the panel mounting series are already equipped with a mounting flange.
The model 111.16 Bourdon tube pressure gauge can be fitted to the panel by menas of a mounting bracket (accessory). The model 111.26 is mounted to the panel by “snapiin mounting” using lateral locating lugs at the case. In addition, metallised front bezels can be supplied for the model 111.26.
The panel mounting series of model 111 is also available in customes-specific versions.
