WIKA operating instructions model TFS35
Typically 15 ... 40 K below the switching temperature
To ensure a safe reset of the switch at low switching
temperatures, care must be taken that the temperature
difference between the measuring point and environment
is high enough; since otherwise the switch cannot cool
back down to the reset switching temperature and thus the
instrument will not be able to return to its normal state.
Note:
Due to short installation length there is a risk that
the temperature at the connector will rise up to an
inadmissibly high value. This absolutely must be taken
into account when designing the measuring point. The
temperature at the connector must not exceed the above
mentioned temperature range.
