2. Design and function
2.1 Description
The model TR33 resistance thermometer consists of a protection tube
with a xed process connection and is screwed directly into the process.
If the resistance thermometer is to be operated in an additional
protection tube, a spring-loaded compression tting must be used.

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. Ensure that mechanical loads on the
connector are minimised, especially in case of increased ambient
temperatures or strong vibration loads.
The electrical connection is made via an M12 x 1 circular connector.
An adapter for electrical connection with angular connector per
DIN EN 175301-803 is optionally available.

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.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.
3.3 Responsibility of the operator
The system operator is responsible for selecting the thermometer
or protection tube, and for the selection of their materials, so as to
guarantee their safe operation within the plant or machine. When
preparing a quote, WIKA can only give recommendations which are
based on our experience in similar applications.
The safety instructions within these operating instructions, as well as the
safety, accident prevention and environmental protection regulations for
the application area must be maintained.
The operator is obliged to maintain the product label in a legible
condition.
3.4 Personnelqualication

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.

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
4.2 “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
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).
4.3 Storage
Permissibleconditionsattheplaceofstorage:
■
Storage temperature: -40 ... +85 °C [-40 ... +185 °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

EN
14073818.10 05/2021 EN/DE/FR/ES
12 WIKA operating instructions model TR33
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.
5. Commissioning, operation
WARNING!
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.
Maximumpermissibletemperatures:
■
At the case with transmitter: 85 °C [185 °F]
■
Class A:
Without neck tube -30 ... +150 °C [-22 ... +302 °F]

5.1 Mounting
These resistance thermometers are designed for screw-tting directly
into the process. The insertion length, along with the ow rate and
viscosity of the process media, may reduce the max. loading on the
protection tube.
If the resistance thermometer is to be operated in an additional
protection tube, a spring-loaded compression tting must be used.
The case must be grounded against electromagnetic elds and
electrostatic charge. It is not necessary to connect the case separately to

contact to the metallic vessel, its components or pipes, and that these
are connected to the equipotential bonding system.
When there is a non-metal contact with the vessel, or with its
structural components or piping, the instrument must be provided with
equipotential bonding.
WARNING!
Neither repairs nor structural modications are permitted, and
any would void the guarantee.

DANGER!
Danger to life caused by electric current
Upon contact with live parts, there is a direct danger to life.
▶
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!
▶
Carry out installation in de-energised state only.
This is protection class 3 equipment for connection at low voltages,
which are separated from the mains voltage or voltages of greater than
AC 50 V or DC 120 V. Preferably, a connection to an SELV or PELV circuit
is recommended; alternatively protective measures from HD 60346-4-41
(DIN VDE 0100-410).
AlternativelyforNorthAmerica
The connection can be made in line with “Class 2 Circuits” or “Class 2
Power Units” in accordance with CEC (Canadian Electrical Code) or
NEC (National Electrical Code).

■
Sensor break and short-circuit
Sensor break or short-circuit are signalled after positive detection
(after approx. 1 second). If this fault condition has been caused by a
malfunction, then a relevant measuring signal must exist for approx.
1 second in order to return to measuring mode. From the time of the
error detection up to the error signalling, the last relevant measured
value will be delivered on the current loop.
Therefore, in the event of a “true” sensor break or short-circuit, this
is also signalled permanently. In the event of a “false” sensor break
or short-circuit, the transmitter has the possibility of reverting to
measuring mode.

■
Medium temperature outside of the span
If the medium temperature exceeds that congured within the
transmitter an error will be signalled.
6. Conguration
Conguration is carried out using a USB interface with a PC via
the model PU-548 programming unit (accessories, order number:
14231581). The connection with the thermometer is made via the
appropriate adapter cable (accessories: M12 x 1 circular connector,
order number: 14003193).
Measuring range, dampening, error signalling, Tag no. and other
parameters can be adjusted (see conguration software).
The measuring range is congurable between -50 ... +250 °C
[-58 ... +482 °F]. 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 or 0.1 °F. The
thermometers are delivered congured to customer specications within
the congurable limits.
Pleasenote:
The measuring range of the thermometer is limited by the application
range of the measuring element, not by the setting range of the
transmitter.
