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.
Depending on the type of application, the electrical
connection must be protected against mechanical damage.
Further important safety instructions can be found in the
individual chapters of these operating instructions.
2.1 Intendeduse
The model TR31 resistance thermometer is used as a general-
purpose thermometer for the measurement of temperatures from
-50 … +150 °C or -58 ... +302 °F (without neck tube) and -50 … +250 °C
or -58 ... +482 °F (with neck tube) in liquid and gaseous media.The
version with mineral-insulated sheathed cable and neck tube allows
to measure temperatures up to 300 °C or 572 °F. It can be used for
pressures up to 140 bar with 3 mm sensor diameters and up to 270 bar
with 6 mm sensor diameters, dependent on the instrument version.
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 instrument malfunction. 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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 electrical personnel
Skilled electrical personnel are understood to be personnel who, based
on their technical training, know-how and experience as well as their
knowledge of country-specic regulations, current standards and directives,
are capable of carrying out work on electrical systems and independently
recognising and avoiding potential hazards.The skilled electrical personnel
have been specically trained for the work environment they are working
in and know the relevant standards and regulations.The skilled electrical
personnel must comply with current legal accident prevention regulations.
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.
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 and in
particular, the safety instructions contained therein.
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct danger of death.
■
Electrical instruments may only be installed and
connected by skilled electrical 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 persons, 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. Design and function
4.1 Description
The model TR31 resistance thermometer consists of a thermowell with
a xed process connection and is screwed directly into the process.
It is designed to be impact and vibration resistant and all electrical
components are protected against humidity (IP67 or IP69K). The
vibration resistance conforms to IEC 60751 (20 g, dependent on the
instrument version).The impact resistance of all versions meets the
requirements of IEC 60751.The electrical connection is made via an
M12 x 1 circular connector or via the directly connected cable.
An adapter for electrical connection with angular connector per
DIN EN 175301-803 is optionally available for the M12 x 1 circular
connector version.

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 and damaged
instruments must not be used.
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:
- M12 x 1, 4-pin circular connector: -40 ... +85 °C (-40 ... +185 °F)
- Directly connected cable: -20 ... +80 °C (-4 ... +176 °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
■
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.

6.1 Mounting
These resistance thermometers are designed for screw-tting 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 housing must be grounded against electromagnetic elds and
electrostatic discharge. It is not necessary to connect the housing
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.
