Abstract (en)
[origin: EP1006756A1] The value of the transmission of a cooking plate (3) in a spectral measurement aperture (18) towards the infrared (IR) radiation sensor (19) is smaller than 10% approaching 0%. A reflection-layer (17) is deposited on wall of a measurement hole (15) to increase of sensitivity the measurement. Under a cooking plate (3), a measurement aperture (18) passes the heat radiation towards the IR sensor (19).
