4.1 Description
The DiwiTherm
thermometer. This compact thermometer can be used in a wide range of applications and
works without an external power supply.
A wide variety of possibilities for the combination of insertion length, neck length, connection
to thermowell etc. are available for the thermometers, suitable for any thermowell and any
application.
®
model TR75 is the ideal combination of a digital display and a resistance
mounted thermowell)
GB
Operation without thermowell is only recommended in certain applications.
Optionally, the DiwiTherm
®
model TR75 can be manufactured with a process connection for
measuring the temperature on a pipe's surface.
®
4.1.1 DiwiTherm
with sensor for insertion
Sensor
Material: stainless steel
Sensor length A ≤ 150 mm: Rigid sensor tube
The tubular design features a rigid construction to the metal sensor tip; therefore tubular
designs must not be bent. Internally, the measuring resistor is connected directly to an
insulated lead. Therefore tubular-design resistance thermometers can only be used up to the
temperatures specied for the lead (see operating temperatures).
Sensor length above 150 mm: Sheathed measuring cable (MI cable)
The junction between the metal part of the sensor and the connecting cable, when using MI
cable, is either crimped, rolled or potted, depending on the design. This area should not be
immersed within the process and must not be bent.
Compression ttings should not be attached to the transition. The type and dimensions of
the transition depend largely on the combination between input leads and metal sensor and
the sealing requirements.
11325232.04 01/2014 GB/D/F/E
WIKA operating instructions DiwiTherm®, model TR75 9
4. Design and function
The sensor diameter should be approx. 1 mm smaller than the bore diameter of the
thermowell or the blind bore, respectively.
Gaps of more than 0.5 mm between thermowell and the sensor will have a negative eect on

4.1.2 DiwiTherm® for mounting in a thermowell
Sensor
Material: stainless steel
The sensor is made from vibration-resistant, sheathed cable (MI cable).
The sensor diameter should be approx. 1 mm smaller than the bore diameter of the
thermowell. Gaps of more than 0.5 mm between thermowell and the sensor will have a
negative eect on the heat transfer, and they will result in unfavourable response behaviour
of the thermometer.
When tting the measuring insert into a thermowell, it is very important to determine the
correct insertion length (= thermowell length for bottom thicknesses of ≤ 5.5 mm). In order to
ensure that the sensor is rmly pressed down onto the bottom of the thermowell, the sensor
must be spring-loaded (spring travel: max 10 mm).

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).
Examine the packaging material carefully so that no accessories that might be packed within
it are lost.
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -20 ... +60 °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 fulls 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.

Mounting on tanks
The geometry of the contact bulb has been
designed for vessels with an external radius
GB
up to 160 mm. If the mounting point of the
skin mounting contact bulb on the tank has
an external radius greater than 160 mm,
we recommend the use of an intermediate
piece designed for the respective tank
diameter, made of a material with good
thermal conductivity. The contact bulb can
be fastened to the tank by means of an angle
bracket with clamping screws, or any similar
method. The contact bulb should have direct
metallic contact with the measuring point
and have rm contact with the surface of the tank.
A heat conductive paste can be used to optimise the heat transmission between contact
bulb and vessel, if temperatures under 200 °C are expected. Insulation must be applied
at the mounting point to avoid error due to heat loss. This insulation must have sucient
temperature resistance and is not included in the scope of delivery.

6. Commissioning, operation
3. Position the indicator as required, tighten the hexagon bolts and slotted screws, and nally
tighten the lock nut or union nut rmly.
Observe the following points during sensor installation:
■
If possible, the entire length of the sensor should be exposed to the temperature being
measured.
■
In pipelines or at other measuring points, the temperature sensor should be directed as
far towards the ow as possible.
■
When using thermowells, ll a thermal contact medium in order to reduce the heat
transfer resistance between the outer wall of the sensor and the inner wall of the
thermowell if possible. The working temperature of the heat conductive paste is
-40 ... +200 °C.
WARNING!
Do not use any heat transfer oil!
6.1 Parallel threads
If the thermometer connecting head, neck tube, thermowell or process connection are
connected with parallel threads (e.g. G ½, M20 x 1.5 ...), these threads must be secured
using seals which prevent liquids from penetrating into the thermometer.
As standard, WIKA uses copper prole seals for the connection between the neck tube
and the thermowell, and at paper seals for the connection of the connection head and the
extension neck or thermowell.
If the thermometer and the thermowell are already connected, the seals will already be
mounted. The plant operator must check whether the seals are suitable for the operating
conditions and must replace them, if necessary, with suitable seals.
GB
For thermometers without a thermowell, and/or where these are delivered separately, the
seals are not included and must be ordered separately.
Tighten the threads by hand when carrying out the nal assembly on the plant. This will
correspond to the delivery status of the premounted components. The nal tightening torque
should be applied using a spanner (half rotation).
The seals must be replaced after dismantling!
The seals can be ordered from WIKA, indicating the WIKA order number and/or
the designation (see table).
