Brief description
The flue gas temperature monitor is used to monitor the flue gas temperature of solid fuel boilers
during bivalent operation with oil heating boilers. Furthermore it is used to block ventilation sys-
tems causing vacuum in connection with tile stoves and fireplaces.
The flue gas temperature monitor operates according to the rod expansion principle. The im-
mersion tube and an integrated metal rod have different expansion coefficients so that a tem-
perature-dependent length difference occurs. A micro switch, which is actuated when a set limit
value temperature is exceeded, is affected due to mechanical transmission. The micro switch
is reset once the immersion tube has cooled down by approx. 10-30 K. In the event of an im-
mersion tube breakage, the current circuit will be permanently opened.
