WIKA operating instructions model TFT35
The integrated thermowell with xed threaded connection or adjustable
compression tting enables direct installation into the process. All wetted
parts and also the case are from stainless steel.
The case and the exchangeable measuring insert are screwed together
using a knurled nut. This enables the exchange of the measuring insert
without having to remove the instrument from the process.
Through the integrated coupler connector, simple installation of the
transmitter is ensured.
The integrated electronics convert the temperature-dependent
resistance signal of the measuring element into a linear unit signal. For
the signal outputs, 4 ... 20 mA, 0 ... 10 V and also 0.5 ... 4.5 V ratiometric
are available.
This instrument is not permitted to be used in hazardous areas!
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.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.

4. Transport, packaging and storage
4.1 Transport
Check the instrument for any damage that may have been caused by
transport.
Obvious damage must be reported immediately and damaged
instruments must not be used.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property
can occur.
▶
When unloading packed goods upon delivery as well as
during internal transport, proceed carefully and observe
the symbols on the packaging.
▶
With internal transport, observe the instructions in chapter
5.2 “Packaging and storage”.
If the instrument is transported from a cold into a warm environment, the
formation of condensation may result in instrument malfunction. Before
putting it back into operation, wait for the instrument temperature and the
room temperature to equalise.
4.2 Packaging and storage
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).
Permissible conditions at the place of storage:
■
Storage temperature: -20 ... +70 °C (-4 ... +158 °F)
■
Humidity: 5 ... 95 % r. h.
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
■
Hazardous environments, ammable atmospheres
4. Transport, packaging and storage

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 instrument as described below:
1. Wrap the instrument in an antistatic plastic lm.
2. Place the instrument, 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!
Physical injuries and damage to property and the
environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene,
ammable or toxic substances), harmful media (e.g.
corrosive, toxic, carcinogenic, radioactive), and also with
refrigeration plants and compressors, there is a danger
of physical injuries and damage to property and the
environment.
Should a failure occur, aggressive media with extremely high
temperature and under high pressure or vacuum may be
present at the instrument.
▶
For these media, in addition to all standard regulations,
the appropriate existing codes or regulations must also
be followed.
▶
Prior to storage, the media must be removed and the
instrument cleaned thoroughly.

WARNING!
Physical injuries and damage to property and the
environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene,
ammable or toxic substances), harmful media (e.g. corrosive,
toxic, carcinogenic, radioactive), and also with refrigeration
plants and compressors, there is a danger of physical injuries
and damage to property and the environment.
Should a failure occur, aggressive media with extremely high
temperature and under high pressure or vacuum may be
present at the instrument.
▶
For these media, in addition to all standard regulations,
the appropriate existing codes or regulations must also
be followed.
CAUTION!
Damage to the instrument
When working on open electric circuits (printed circuit
boards) there is a risk of damaging sensitive electronic
components through electrostatic discharge.
▶
The correct use of grounded working surfaces and
personal armbands is required.
WARNING!
Damage to the instrument
Through exceeding the permissible temperature at the case
of 85 °C, the electronic components can be damaged or
destroyed.
▶
Observe the maximum permissible temperature at the
case: 85 °C (185 °F)
Avoid putting any mechanical loading on the electrical connections and
on the cases. Connections must only be opened once the instrument has
been depressurised and has cooled down.

5.1 Mounting
This compact temperature transmitter is intended to be screwed directly
into the process. The insertion length, along with the ow velocity and
viscosity of the process media, may reduce the max. loading on the
thermowell.
The case must be grounded against electromagnetic elds and
electrostatic charge. It is not necessary to connect the case separately to
the equipotential bonding system, provided that it has a xed and secure
contact to the metallic vessel, its components or pipes, and that these
are connected to the equipotential bonding system.
When there is a non-metallic contact with the vessel, or with its
structural components or piping, the instrument must be provided with
equipotential bonding.

For information on tapped holes, refer to DIN 3852 or for NPT threads to
ANSI B 1.20.
