ABSTRACT:
Proposed is a temperature measuring device for a regulating circuit (10) in particular of an electrical radiant heating appliance with a heating conductor (2) arranged beneath a glass ceramic cooking surface (1), in which the heating conductor (2) itself suffices for temperature detection. There is provided a change-over switch (6) which cyclically connects the heating conductor (2) to a resistance measuring circuit (7). It detects the respective temperature-dependent ohmic resistance value of the heating conductor (2) and produces a temperature-proportional control signal for the regulating circuit (10).
