2.3 Safety instructions for pressure gauges per ATEX
Permissible ambient temperature
-20 ... +60 °C
-40 ... +60 °C
-70 ... +60 °C
Attention! With gaseous media, the temperature may increase as a result of
compression warming. In these cases it may be necessary to throttle the rate of
change of pressure or reduce the permissible medium temperature.
Permissible medium temperature
≤ 100 °C
≤ 150 °C (option)
≤ 200 °C (option)
The permissible medium temperature does not only depend on the instrument
design, but also on the ignition temperature of the surrounding gases, vapours or
dusts. Both aspects have to be taken into account.
