For applications requiring equipment category 1/2G, the process pressure of the media must be
between 0.8
…
1.1 bar. If OPTIBAR DP 7060 VGK7*A/W/V E/Z/6/7 are operated at temperatures
higher than those specified in the table above, please make sure by means of appropriate
measures that there is no danger of ignition from the hot surface. The maximum permissible
temperature of the electronics/housing should not exceed the values given in the table above.
The application conditions in areas without hazardous mixtures are specified in the
manufacturer information.
