injury or death, if not avoided.

CAUTION!

... indicates a potentially dangerous situation that can result in light injuries

or damage to property or the environment, if not avoided.

DANGER!

... identifies hazards caused by electric power. Should the safety

instructions not be observed, there is a risk of serious or fatal injury.

WARNING!

... indicates a potentially dangerous situation that can result in burns,

caused by hot surfaces or liquids, if not avoided.

Information

... points out useful tips, recommendations and information for efficient

and trouble-free operation.

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.
