The safety temperature controller model STW15 has been designed for the operating medium of air (flue gas). It will open a control circuit when the temperature on the temperature sensor exceeds the non-adjustable set point.

Damage to the measuring system also leads to an interruption of the circuit, as required by the enhanced safety. The measuring system is coupled with a pointer which displays the respective temperature status on a scale.
