Abstract (en)
Flame detection for combustion appliances. A sensor configuration comprising a sensor (1) with sensor terminals, the at least a sensor (1) being configured to produce a signal offset when receiving at least 1.1 Lux, and to produce equal signals when receiving less than 1.1 Lux, a differential amplifier (2) produces a current at its output channel (3) in response to the signal offset applied to its input channels, a load member (6) dissipates a first amount of power as a function of the current produced at the output channel (3), the differential amplifier (2) draws a first load current from the supply terminals (7, 8) in response to the signal offset applied by the sensor (1) to its input channels, the differential amplifier (2) draws a second quiescent current from the supply terminals (7, 8) in response to equal signals applied to its input channels (-, +).
