ABSTRACT:
An electric radiant heater is constructed with a pot detection system for switching on one or more heating areas. The pot detection system operates inductively according to the resonant circuit detuning principle. The sensor consists of a single-turn loop made from thick wire and which in the vicinity of the heating areas is positioned above the latter and just below a glass ceramic plate. In the case of a two-circuit heater, the sensor loop is shaped with clearly defined circumferential areas in said heating areas, so that the signal has a stepped transition between these areas and consequently a pot size detection in adaptation to the heating areas is possible.
