Abstract (en)
[origin: WO2007136268A1] The invention relates to an electric heating device for heating material such as liquid, wherein the heating device comprises a substantially flat carrier of material with good thermal conduction, on a first side of which material for heating can be placed, an electrically insulating layer arranged on the second side of the carrier, heating conductors arranged on the electrically insulating layer, connecting means for connecting the heating conductors to a source of electrical energy and a control circuit connected between the connecting means and the heating conductors, wherein at least one detector electrode is arranged which is in contact with the electrically insulating layer and connected to the control circuit, wherein the control circuit is adapted to measure the detector current flowing through the detector electrode and wherein the control circuit is adapted to give a signal when the detector current exceeds a predetermined value.
