mains or for voltages higher than AC 50 V or DC 120 V. A connection to SELV circuits
or alternatively to circuits with a protective measure according to IEC 60364-4-41 is
recommended.
For further specifications see WIKA data sheet TV 18.01 and the order documentation.
4. Design and function
4.1 Description
The closed measuring system with liquid filling consists of a temperature sensor, a
capillary and a Bourdon tube.The volume change as a consequence of the heat applied
to the temperature sensor, and thus the pressure change in the closed system, is
transmitted through the capillary to the Bourdon tube and then indicated on the dial by
an angular deflection of the pointer shaft.
Through the combination of a mechanical measuring system and electronic signal
processing, the process temperature can be read securely, even if the power supply is lost.

3. Specifications / 4. Design and function

10 WIKA operating instructions model TGT70
EN
14047194.03 03/2022 EN/DE/FR/ES
The built-in Bourdon tube system generates a rotational pointer movement that is
proportional to the temperature. An electronic angle encoder (non-contact, and
therefore completely free from wear and friction) determines the position of the
instrument pointer. From this, the electrical output signal is produced, proportional to the
temperature.
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.
5. Transport, packaging and storage
5.1 Transport
Check the 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, flammable atmospheres
Store the instrument in its original packaging in a location that fulfils 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 film.
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!
Before storing the instrument (following operation), remove any residual
media.This is of particular importance if the medium is hazardous to health,
e.g. caustic, toxic, carcinogenic, radioactive, etc
.

6. Commissioning, operation
WARNING!
▶
Only work on the gauge with the voltage disconnected.
▶
Avoid strong vibrations and mechanical impacts during operation of the
instrument.
▶
Avoid soiling and strong fluctuations of the ambient temperature.
▶
Cutting through the measuring line will destroy the instrument and thus
lead to a wrong electrical output signal.
▶
Cutting through the capillary will destroy the instrument and lead to the
leakage of the thermometric liquid (Xylol, Syltherm or silicone oil).
6.1 Installation conditions
Before mounting the sensor, check whether the sensor material used (specified in the
delivery note) is chemically resistant/neutral to the medium being measured.This also
applies to thermowells.
The working pressure at the thermowell stem is permitted up to a maximum of 25 bar
(static).
Make sure that the suitable accessories required for fastening the case of the instrument
into the panel are available. The accessories are either fitted or located in a bag
fastened to the thermometer.
■
Expose, if possible, the entire length of the stem to the temperature to be measured.
However, at least the length of the active part that corresponds to the length of the
expansion vessel (active length).
■
The temperature probe in pipelines or other measuring points must be angled as far
towards the flow as possible.
■
When using thermowells, please observe that the stem must not touch the bottom of
the thermowell.
■
Protect capillaries against bending.The smallest bending radius of the capillary
should not be less than 6 mm. Any bending or discontinuities of the capillary may
result in the failure of the instrument.
■
If the sensor is is installed in a location which is exposed to shock and vibration, it
is essential that the capillary is coiled in several loops between the last attachment
point and the sensor, and free from tension. Any excess length must also be coiled,
since cutting would render the instrument unserviceable.
■
Avoid welding or soldering and permanent fastening of the capillary as this could
seriously damage the capillary and impair the operation of the instrument.
■
The dial casing must be mounted free from vibration.
■
If necessary, it is possible to isolate the instrument from the mounting point by instal-
ling a flexible connection line between the measuring point and the thermometer and
mounting the instrument on a suitable bracket.
If this is not possible, do not exceed the following limits:
Frequency range < 150 Hz
Acceleration < 0.7 g (7 m/s2)

14047194.03 03/2022 EN/DE/FR/ES
6.2 Ambient conditions
Unless the ingress protection of the thermometer‘s housing is specifically identified
in the order confirmation, the instrument must be protected from humid air and other
aggressive atmospheres.
To ensure the best measuring accuracy possible, the ambient temperature on the
indicator case should be between 0 ... 40 °C. Higher or lower ambient temperatures can
cause indication errors.
6.3 Indicator check
Indicator checks should only be carried out in comparison with a more accurate instru-
ment or, if possible, with a calibrated instrument.The temperature during the check must
remain constant. Fluctuating temperatures can lead to reading errors caused by the
different response times of the sensors.
Before checking the indicators of thermometers without thermowells, a waiting time of at
least 5 minutes with the stem's full length properly inserted is required to allow tempera-
ture equalisation.
Temperature checks using thermometers with sensors assembled with thermowells
can, in many cases, only result in a reference temperature at the instrument under
test, due to permanent heat dissipation caused by the thermowell. In temperature
applications fitted with static checking thermometers (e.g. pipeline systems), permanent
offsets in reference temperatures can also be caused by the measuring path.
Ambient temperatures around the indicator case which differ substantially from room
temperature can lead to steady indication errors with constant ambient temperatures
and to varying indication errors with fluctuating ambient temperatures.
Permanent indication errors caused by the ageing of the measuring system can be
ignored, as they only account for a fraction of the indication accuracy.
6.4 Zero adjustment
A zero adjustment may only be carried out by the manufacturer or in adequately equip-
ped workshops by qualified persons.
■
The electrical connection must only be made by qualified skilled personnel.
■
Connect the switch via cable terminal box.
■
Conductor cross section max. 1.5 mm2
■
The terminal assignment is stated on the product label of the thermometer.

7. Maintenance and cleaning
7.1 Maintenance
This expansion 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 exclusively be carried out by the manufacturer or by appropriately quali-
fied personnel.
