2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate
resistance thermometer has been selected in terms of measuring range,
design, specic measuring conditions and appropriate wetted parts' materials
(corrosion).
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
Model TR30 and TR31 resistance thermometers are used as general-purpose thermometers
for the measurement of temperatures from -50 … +150 °C (without neck tube) and
-50 … +250 °C (with neck tube) in liquid and gaseous media. They can be used for pressures
up to 40 bar (special designs to 400 bar dependent on insertion length and diameter).
The instrument 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 instrument outside of its technical specications
requires the instrument to be taken out of service immediately and inspected by an
authorised WIKA service engineer.

If the instrument is transported from a cold into a warm environment, the formation of
condensation may result in the instrument malfunctioning. Before putting it back into
operation, wait for the instrument temperature and the room temperature to equalise.
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 independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive
media.
2.3 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, ammable or toxic gases or
liquids, and refrigeration plants, compressors, etc., in addition to all standard
regulations, the appropriate existing codes or regulations must also be
followed.
WARNING!
Protection from electrostatic discharge (ESD) required.
The proper use of grounded work surfaces and personal wrist straps is
required when working with exposed circuitry (printed circuit boards),
in order to prevent static discharge from damaging sensitive electronic
components.
2. Safety

11377551.05 06/2012 GB/D/F/E
WIKA operating instructions models TR30, TR31 7
GB
To ensure safe working on the instrument, the operating company must ensure
■
that suitable rst-aid equipment is available and aid is provided whenever
required,
■
that the operating personnel are regularly instructed in all topics regarding
work safety, rst aid and environmental protection, and know the operating
instructions, in particular the section on safety instructions.
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct danger of death.
■
The instrument may only be installed and mounted by skilled personnel.
■
Operation using a defective power supply unit (e.g. short circuit from the
mains voltage to the output voltage) can result in life-threatening voltages at
the instrument!
WARNING!
Residual media in dismounted instruments can result in a risk to personnel, the
environment and equipment.
Take sucient precautionary measures.
Do not use this instrument in safety or Emergency Stop devices. Incorrect use
of the instrument can result in injury.
Should a failure occur, aggressive media with extremely high temperature and
under high pressure or vacuum may be present at the instrument.

4.1 Description
The models TR30 and TR31 resistance thermometers consist of a thermowell with
xed process connection, and are screwed directly into the process. They are designed
to be resistant to shock and vibration and all electrical components are protected
against splashed water. The vibration resistance of the standard version complies with
DIN EN 60751 (up to 3 g); specic designs can withstand up to 10 g. The impact resistance
for all versions meets the requirements of DIN EN 60751. The electrical connection is made
via a angular DIN connector, Form A (TR30) or M12 x 1 circular connector (TR30, TR31).

5. Transport, packaging and storage / 6. Commissioning, ...
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 transport (e.g. change in
installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: 0 ... 70 °C
■
Humidity: 35 ... 85 % relative humidity (no condensation)
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 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!
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!
Avoid putting mechanical stress on the electrical connections or on the
enclosures. The maximum temperatures of -50… +150 °C (without neck
tube) and -50 … +250 °C or -50 ... +200 °C for TR30-V (with neck tube) must
not be exceeded. Connections must only be opened when the instrument is
depressurised and has cooled down.

The lower limit of the measuring range is congurable between -50 ...+150 °C.
The possible upper limit of the measuring range is dependent on the respective lower limit of
the measuring range. For possible combinations of lower and upper limits of the measuring
range, see diagram. For clarity, this dependency has been shown in 50 °C steps in the
examples in this diagram. The conguration software checks the required measuring range
and will only accept permissible values. Intermediate values are congurable; the smallest
increment is 0.1 °C. The thermometers are delivered with a basic conguration (0 ... +150 °C,
downscale) or congured to customer specications within the congurable limits.
With conguration to customer specications, the measuring range will be shown clearly
on the instrument label. The conguration and the choice of parameters is described in the
menu-driven conguration software. Changes to the conguration must be noted on the
label using a water-resistant felt-tip pen.

Please note:
The measuring range of the
thermometer is limited by
the application range of the
measuring element, not by
the adjustable range of the
transmitter.
