Operating Temperature - WIKA 632.50.100 Instructions D'utilisation

3. Technical data and use in accordance with intended use

Operating Temperature

Ambient: -20 ... +60 °C
Attention: Footnote 1) under table 1 must be absolutely taken into account!
GB
Medium: see table 1
Attention! With gaseous substances the temperature may increase as a result
of the compression temperature. In such cases the pressure change rate has to
be slowed down resp. the permissible medium temperature has to be reduced.
Table 1: Permissible medium temperature (only mechanical part)
Ignition temperature of

> 85 °C (T 6)
> 100 °C (T 5)
> 135 °C (T 4)
> 200 °C (T 3)
> 300 °C (T 2)
> 450 °C (T 1)
1) The permissible uppper ambient temperature for the electrical components is determined by the
electrical connection values and the ignition temperature of the ambient gases, vapours and dusts.
Therefore the maximum permissible ambient temperatures specified in the EC-type examination
certificates for slot-type sensors and SN sensors must be observed as well. The lower of these two
values is to be considered the maximum permissible ambient temperature!
