1. Safety
1.2 Intended use
These bimetal thermometers are used for measuring temperature in
hazardous areas of industrial applications.
The instrument has been designed and built solely for the intended
use described here, and may only be used accordingly.
Check whether the classication is suitable for the application (see Ex
marking, chapter 1.5 “Labelling, safety marks”). Observe the relevant
national regulations.
The non-observance of the instructions for use in hazardous areas
can lead to the loss of the explosion protection. Adhere to the
following limit values and instructions (see data sheet).
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.
1.3 Responsibility of the operator
The responsibility for classication of zones lies with the plant
operator and not the manufacturer/supplier of the equipment.
1.4 Personnel qualication
The skilled personnel must have knowledge of ignition protection
types, regulations and provisions for equipment in hazardous areas.

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
2) Maximum surface temperature
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!
Ambient temperature: -20 … +60 °C
Medium temperature: max. +600 °C
(instruments with liquid lling: 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.
For instruments with liquid lling, 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.

1) only for instruments without liquid lling
Hazardous dust atmosphere
For dusts, the procedure specied in ISO/IEC 80079-20-2 for
determining the ignition temperature has to be applied. The
ignition temperature is determined separately for dust clouds and
dust layers, respectively. For dust layers, the ignition temperature
depends on the dust layer thickness per EN/IEC 60079-14.

The permissible maximum medium temperature must not exceed
the lowest determined value, even in case of a malfunction.
3) Mount the instrument in such a way that, taking into consideration
the inuence of convection and heat radiation, no deviation above
or below the permissible ambient and medium temperatures can
occur.

3. Special conditions for use (X conditions)
4) The end user must ensure that the measuring instrument is
connected to the equipotential bonding of the end-use application
via the process connection. The sealings used at the process
connection must be electrically conductive.
EN
5) Avoid handling of materials that react dangerously with the
materials used for the instrument, and substances liable to
spontaneous combustion.
6) Avoidance of vibration
Requirements for the installation point
If the line to the instrument is not adequately stable, an instrument
holder should be used for fastening. If vibrations cannot be avoided
by means of suitable installation, use instruments with liquid lling.
Protect the instruments against coarse dirt and wide uctuations in
ambient temperature.
Permissible vibration load at the installation site
Always install the instruments in locations free from vibration. If
necessary, it is possible to isolate the instrument from the mounting
point, e.g. by installing a exible connection line between the
measuring point and the instrument and mounting the instrument
on a suitable bracket. If this is not possible, do not exceed the
following limits:
Frequency range < 150 Hz
Acceleration < 0.5 g
7) When using thermowells, they must be lled with a thermal contact
medium in order to reduce the heat transfer resistance between
the outer wall of the probe and the inner wall of the thermowell. The
working temperature of the thermal compound is -40 ... +200 °C.
8) Clean the thermometer with a moist cloth. Ensure that due to the
cleaning no electrostatic charge will be generated.
