Abstract (en)

[origin: US5296682A] A cooktop assembly has a glass-ceramic cooktop, a radiant heater defining a heating zone of the cooktop, and a metal sensor disposed under the cooktop inside or outside the heating zone. A mains voltage contact protector for the sensor includes operating the sensor at a higher-frequency operating point than for normal operation, and a rejection filter being connected to the sensor and dimensioned for mains voltage contact protection.
