2. Safety
WARNING!
Before installation, commissioning and operation, ensure
that the appropriate bimetal thermometer has been
selected in terms of measuring range, design and specic
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 the equipment.
Further important safety instructions can be found in the
individual chapters of these operating instructions.
2.1 Intended use
The combined bimetal thermometer is mainly used in the process
industry to monitor process temperatures.
The combined bimetal thermometer has been designed and built
solely for the intended use described here, and may only be used
accordingly.
The technical specications contained in these operating instructions
must be observed. Improper handling or operation of the combined
bimetal thermometer outside of its technical specications requires
the instrument to be taken out of service immediately and inspected
by an authorised WIKA service engineer.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.

2.2 Personnel qualication
WARNING!
Risk of injury if qualication is insucient!
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 qualications described below.
■
Keep unqualied personnel away from hazardous
areas.
Skilled personnel
Skilled personnel are understood to be personnel who, based on
their technical training, knowledge of measurement and control
technology and on their experience and knowledge of country-
specic regulations, current standards and directives, are capable
of carrying out the work described and of independently recognising
potential hazards.
2.3 Special hazards
WARNING!
Residual media in dismounted instruments can result in
a risk to persons, the environment and equipment. Take
sucient 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
This series of thermometers is designed for installation in pipes,
vessels, plant and machinery.
The „Twin-Temp“ combined bimetal thermometer oers two
measuring systems in one instrument.
A bimetal thermometer enables the visualisation of measured values
on site without power supply, while, in addition, the integrated Pt100
resistance sensor provides an electrical signal for further processing.
This design is particularly recommended for safety-critical applica-
tions and in case of limited space where the process can be opened
only at one place.

4.2 Scope of delivery
Cross-check scope of delivery with the delivery note.
5. Transport, packaging and storage
5.1 Transport
Check the instrument for any damage that may have been caused
during transportation.
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 trans-
port (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
■
Potentially explosive environments, ammable atmospheres
Store the instrument in its original packaging in a location that fulls
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, packaging and storage

WARNING!
Before storing the instrument (following operation),
remove any residual media. This is of particular impor-
tance 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
When screwing the instrument 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.
6. Commissioning, operation
Installation with
spanner
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!

6. Commissioning, ... / 7. Maintenance and ...
CAUTION!
When using thermowells, please
ensure that the stem does not
touch the bottom of the thermowell
since, due to the dierent
expansion coecients of the
materials, the stem may become
buckled at the bottom of the
thermowell.
(Formula for the calculation of the
stem length l1 see the respective
thermowell‘s data sheet)
7. Maintenance and cleaning
7.1 Maintenance
The combined bimetal thermometer is maintenance-free!
The indicator should be checked once or twice every year. To do this
the instrument must be disconnected from the process and checked
using a temperature calibrator.
Repairs must only be carried out by the manufacturer.
7.2 Cleaning
CAUTION!
■
Clean the thermometer with a moist cloth.
■
Wash or clean the disconnected thermometer before
returning it in order to protect personnel and the
environment from exposure to residual media.
