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 equipment.
Further important safety instructions can be found in the
individual chapters of these operating instructions.

2.1 Intended use
These bimetal thermometers are mainly used in the process industry
for monitoring the process temperature.
The 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 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 should qualication be 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 regulati-
ons, current standards and directives, are capable of carrying out the
work described and 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 tempe-
rature 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, dierent 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.
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.
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
■
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.
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).

loosening
Make sure to loosen the screws
on the opposite side as well!
6. Commissioning, operation
When screwing the gauges in, the force required for this must not
be applied through the case or terminal box, rather only through the
spanner ats provided for this purpose (using a suitable tool).
6. Commissioning, operation
Installation with
spanner
When mounting a bimetal thermometer that can be rotated and
swivelled, the specic 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 connec-
tion.
2. The hexagon bolts and slotted screws at the swivel joint must be
loosened.
3. Position the indicator as required, tighten the hexagon bolts and
slotted screws, and nally tighten the lock nut or union nut rmly.
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.

6. Commissioning, operation / 7. Maintenance ...
WARNING!
Do not ll hot thermowells. There is a risk of the oil spray-
ing out!
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
These bimetal thermometers are 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.

"8.2 Returns".
8. Dismounting, return and disposal
WARNING!
Residual media in dismounted instruments can result in
a risk to persons, the environment and equipment. Take
sucient precautionary measures.
8.1 Dismounting
WARNING!
Risk of burns!
Let the instrument cool down suciently before
dismounting it! When dismounting it, there is a risk that
dangerously hot pressure media may escape.
8.2 Return
WARNING!
Absolutely observe when shipping the instrument:
All instruments delivered to WIKA must be free from any kind
of hazardous substances (acids, bases, solutions, etc.).
