2.2 Description
The model TR36 resistance thermometer consists of a thermowell/
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.
They are designed to be resistant to shock and vibration and all electrical
components are protected against splash water.The vibration resistance
conforms to IEC 60751 (8 g, dependent on the instrument version). The
impact resistance of all versions meets the requirements of IEC 60751.

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 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: -40 ... +85 °C [-40 ... +185 °F]
■
Humidity: 5 ... 95 % r. h. (non-condensing)
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 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.
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.
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]
With neck tube -30 ... +250 °C [-22 ... +482 °F]

5.1 Installation
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
the equipotential bonding system, provided that it has a xed and secure
contact to the metal 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.

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).

5.3 Behaviour of the 4 ... 20 mA electrical output signal
■
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 the span
If the medium temperature exceeds that congured within the
transmitter, the transmitter will operate in a linear fashion within the
following limits: 3.8 mA (MRS); 20.5 mA (MRE). If these limits are
exceeded, then an error will be signalled.
■
Hysteresis on return to the measuring span
After the linear error limits have been exceeded, on return to the
measuring span, a hysteresis of 0.1 mA must be passed.This
hysteresis prevents the transmitter from jumping back and forth
between error signalling and measuring mode.

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: DIN connector, order number: 14005324).
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.
Maximum permissible temperatures:
■
At the case with transmitter: 85 °C [185 °F]
■
Class A:
Without neck tube -30 ... +150 °C [-22 ... +302 °F]
With neck tube -30 ... +250 °C [-22 ... +482 °F]
