The model 111.11 and 111.31 pressure gauges have been specifically designed for gas welding equipment and meet all requirements of the ISO 5171 standard.
The instruments are based on the proven Bourdon tube measuring system. On pressurisation, the deformation of the Bourdon tube, proportional to the incident pressure, is transmitted to the movement via a link and indicated.
The modular design of the pressure gauge enables a multitude of combinations of case materials, process connections, nominal sizes and scale ranges.
Due to this high variance, the instruments are suitable for many applications within the welding engineering sector. An individualisation of the instruments by means of dial printings, such as company logos, is possible.
The safety version of the model 111.31 pressure gauges has a solid baffle wall and also fulfils increased safety requirements regarding personal protection.
