DANGER!
Danger to life from missing instrument grounding
With missing or incorrect grounding, there exists a risk of
dangerous voltages (leading to, for example, mechanical
damage, electrostatic charge or induction).
▶
Ground thermometer!
Observe the special conditions (see chapter 3 “Special conditions for
use (X conditions)”, point 4).
3. 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.
