3.2 Intended use
The model TFS35 bimetal temperature switches are used to limit temperatures within a
wide variety of industrial applications.The TFS35 are temperature limiting instruments.
They are not intended to provide any safety or protective functionality.They are
designed for use in environments up to pollution degree 2.
They monitor the temperature of machinery and equipment during normal operation
and, for example, switch off machinery if it overheats.
Bimetals form the basis of the model TFS35 temperature switches.Temperature
sensing is carried out by a bimetal disc, which snaps over when the Nominal Switching
Temperature (NST) is reached. After cooling back down to the reset switching
temperature (RST), the switch returns to its original state, so that the monitored
equipment can again work normally.

Temperature ranges
Reset Switching Temperature
(RST)
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.
Ambient temperature 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.
