Maximum temperature specifications for Ex use
Device temperature classification with and without dust is related to the process temperature
and ambient temperature as listed below.
The maximum allowable process fluid temperatures with respect to temperature class for the
device when used with potentially explosive gases in a maximum ambient temperature of
+60°C are:

Additionally, the maximum surface temperature of the overall device shall be:
●
If Tprocess ≤ 85°C, maximum surface temperature = 85°C.
●
If Tprocess > 85°C, maximum surface temperature = process temperature.
