5. Special conditions for use (X conditions)

1) Design temperatures
Ambient temperature: -20 ... +60 °C
Medium temperature: max. +600 °C
(instruments with liquid filling: max. +250 °C)
Observe the surface temperature for ATEX application:
The permissible medium temperature does not only depend on
the instrument design, but also on the ignition temperature of the
surrounding gases, vapours or dust. Take both aspects into account.
2) Maximum surface temperature
For instruments with liquid filling, make sure that the medium
temperature is lower than 250 °C.
The surface temperature mainly depends on the medium
temperature. For prevention, consider the maximum medium
temperature as maximum surface temperature.
