Through the high protection class of the thermometer (IP65) and its
liquid damping, operation under vibration conditions is possible.
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.
5. Special conditions for use (X conditions)
1) Design temperatures
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.
2) Maximum surface temperature
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 specied 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.
Ignition temperature
of dust
Maximum permissible medium
temperature (in the measuring system)
Dust cloud T
cloud < 2/3 Tcloud
Dust layer Tlayer < Tlayer − 75 K − (reduction depending on the
layer thickness)
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 inuence of convection and heat radiation, no deviation above or
below the permissible ambient and medium temperatures can occur.
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.
5. Special conditions for use (X conditions)

EN
11583747.04 12/2016 EN/DE/FR/ES
12 WIKA operating instructions models 53, 54, 55 (ATEX)
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.
