2.1 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.
The technical specications contained in these operating instructions
must be observed. Improper handling or operation of the instrument
outside of its technical specications requires the instrument to be
taken out of service immediately and inspected by an authorised
WIKA service engineer.
Before installation, commissioning and operation, ensure
that the appropriate bimetal thermometer has been
selected in terms of measuring range, design and specic
measuring conditions. The compatibility of the wetted
parts of the process connection (thermowell, thermowell
stem) with the medium must be tested.
Non-observance can result in serious injury and/or
damage to equipment.
Further important safety instructions can be found in the
individual chapters of these operating instructions.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.

2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and
damage to equipment.
■
The activities described in these operating instructions
may only be carried out by skilled personnel who have
the qualications described below.
■
Keep unqualied personnel away from hazardous
areas.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their

and on their experience and knowledge of country-specic regulations,
current standards and directives, are capable of carrying out the work
described and of independently recognising potential hazards.
2.3 Additional safety instructions for instruments per ATEX
WARNING!
Non-observance of these instructions and their contents
may result in the loss of explosion protection.
WARNING!
It is imperative that the application conditions and safety
requirements of the EC-type examination certicate are
followed.
Temperature measuring instruments must be earthed via
the process connection!
GB
Bimetal thermometers contain no internal heat source, and, when
correctly installed and operated, cause no increase in temperature!
11583747.03 10/2013 GB/D/F/E
WIKA operating instructions models 53, 54, 55 (ATEX) 7
2. Safety
A heat return ow from the process, which exceeds the ignition
temperature of the surrounding hazardous area, is not permitted and
must be prevented through appropriate thermal insulation!
GB
The following surface temperatures must not be exceeded:
Potentially explosive atmosphere
Gas, air, vapour, mist Dust, air
Permissible
surface
temperature
1) If dust should settle on the instrument (up to a max. 5 mm layer thickness), a safety margin
of 75 K must be maintained between the minimum ignition temperature of the dust layer
and the surface temperature! For thicker dust layers a greater safety margin should be
incorporated!
2.4 Special hazards
≤ 80 % of the ignition
temperature in °C
≤ 2/3 of the minimum
ignition temperature
1)
in °C
WARNING!
Observe the information given in the applicable type
examination certicate and the relevant countryspecic regulations for installation and use in potentially
explosive atmospheres (e.g. IEC 60079-14, NEC, CEC).
Non-observance can result in serious injury and/or
damage to the equipment.
For additional important safety instructions for insturments
with ATEX approval see chapter 2.3 “Additional safety
instructions for instruments per ATEX”.
WARNING!
Residual media in dismounted instruments can result in
a risk to persons, the environment and equipment. Take
sucient precautionary measures.

WARNING!
For lled instruments, make sure that the medium
temperature is lower than 250 °C.
Reason: The sheath also contains a lling liquid; at a
temperature > 250 °C, this liquid may become cloudy or
change colour or, in some cases, may ignite.

4. Design and function
4.1 Description
The bimetal thermometers of this series are intended for installation in
pipelines, vessels, plant and machinery.
Sheath and case are made of stainless steel.
To allow tting to the process, dierent installation lengths and
process connections are available.
Through the high protection class of the thermometer (IP 65) and its
liquid damping, operation under vibration conditions is possible.

5. Transport, packaging and storage
5.1 Transport
Check instrument for any damage that may have been caused by
transport.
Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during
transport (e.g. change in installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: -20 ... +60 °C
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
Store the instrument in its original packaging in a location that fulls
the conditions listed above. If the original packaging is not available,
pack and store the thermometer as described below:
1. Wrap the thermometer in an antistatic plastic lm.
2. Place the thermometer, along with shock-absorbent material, in the
packaging.
3. If stored for a prolonged period of time (more than 30 days), place a
bag, containing a desiccant, inside the packaging.

5. Transport ... / 6. Commissioning, operation
WARNING!
Before storing the instrument (following operation),
remove any residual media. This is of particular
GB
importance if the medium is hazardous to health, e.g.
caustic, toxic, carcinogenic, radioactive, etc.
The use of liquid damping is always recommended for
temperatures near the dew point (±1 °C around 0 °C).
6. Commissioning, operation
The bimetal thermometer must be earthed via the process
connection!
When screwing the instruments in, the force required to do this must
not be applied through the casing, but only through the spanner ats
provided for this purpose and using a suitable tool.
Installation with
open-ended spanner
When mounting a bimetal dial indicating thermometer that can be
rotated and swivelled, the specic instructions must be followed. In
order to set the indicator to the desired position, the following steps
must be taken:
1. The lock nut or union nut must be loosened at the process
connection.
2. The hexagon bolts and slotted screws at the swivel joint must be
loosened.

6. Commissioning, operation
loosening
Make sure to loosen the screws
on the opposite side as well!
3. Position the indicator as required, tighten the hexagon bolts and
slotted screws, and nally tighten the lock nut or union nut rmly.
Permissible vibration load at the installation site
The instruments should always be installed in locations free from
vibration.
If this is not possible, the following limit values must not be exceeded:
Frequency range < 150 Hz
Acceleration < 0.5 g (5 m/s2)
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 sensor and the inner wall of the thermowell. The
working temperature of the thermal compound is -40 ... +200 °C.
WARNING!
Do not ll hot thermowells. There is a risk of the oil
spraying out!
