Temperature ranges
Measuring range
■
The measuring range is dependent, essentially, on the material of the housing and the
EN
measuring element. The housing is designed for a temperature range of -40 ... +100 °C. In
conjunction with the measuring element, the following measuring ranges are available:
Measuring element
Pt100
Pt1000
NTC
Ambient temperature
■
The permissible ambient temperature range is identical to the measuring range.
Storage temperature
■
-20 ... +70 °C
Protect the measuring instruments from humidity and dust!
Ingress protection
IP 65
The connection housing is protected from dust and water jets.
For further specifications see WIKA data sheet TE 67.17 and the order documentation.

4. Design and function

4.1 Description
The model TF41 ambient temperature sensor consists of a plastic case with integrated
connection terminals and a measuring element which is also integrated in the case as standard.
In order to improve the response behaviour, one can optionally order the TF41 with external
sensor sleeve.
For faster temperature measurement, the TF41 can alternatively be delivered with an external
sensor shaft. To prevent erroneous measurements through strong radiation from sunlight, we
offer a clip-on sun cover as an accessory. To affix the ambient temperature sensor to the building
wall, a wall-mounting kit is available (see chapter 9 "Accessories").
All electrical components are protected against splash water. The electrical connection is made
via connection terminals in the case.
