knowledge of measurement and control technology and on their experience and knowledge
of country-specific regulations, current standards and directives, are capable of carrying out
the work described and independently recognising potential hazards.
Special knowledge for working with instruments for hazardous areas:
The skilled personnel must have knowledge of ignition protection types, regulations and

Permissible ambient temperature
-20 ... +60 °C
-40 ... +60 °C
Permissible medium temperature
-20 ... +100 °C
-20 ... +200 °C
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.

On the wetted parts of the instrument, small residual amounts of the adjust-
ment medium (e.g. compressed air, water, oil) can adhere from production.
With increased requirements for technical cleanliness, suitability for the appli-
cation must be checked by the operator before commissioning.
