4. Design and function

4.1 Description
The model TF44 strap-on temperature sensor consists of an aluminium thermowell with
integrated measuring element and a securely fixed connecting lead.
It is used for temperature measurement on pipe surfaces and can be secured by means of a
worm-drive hose clip. Due to the materials, the geometry and the construction of the TF44, it is
not necessary to apply heat-transfer paste between the sensor sleeve and the pipeline. If desired
anyway, a small quantity of heat-transfer paste is sufficient.
Worm-drive hose clips in various diameter ranges and heat-transfer paste can be ordered from
WIKA as accessories. For the part numbers of these see data sheet TE 67.14.
All electrical components are protected against splash water. The electrical connection is made
via the connecting lead.

4.2 Scope of delivery

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).
5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: -20 ... +70 °C
■
Humidity: 35 ... 85 % relative humidity (no condensation)
■
