Abstract (en)

[origin: EP3059496A1] A measuring arrangement (43) for a gas burner, comprising: a flame rod (13); a first power supply device (26) configured to apply a supply voltage to the flame rod (13), wherein the first power supply device (26) is configured to be switched on and off thereby switching on and off the supply voltage to the flame rod (13); a measuring device (27) configured to measure a flame ionization current at the flame rod (13) with the aid of the supply voltage applied to the flame rod (13), wherein the flame ionization current is measurable with the supply voltage being switched on and with the supply voltage being switched off; a microcontroller (44) for receiving the flame ionization current from the flame rod (13). The measuring arrangement (43) further comprises an input definition circuit (34) configured to switch the measuring arrangement (43) between a relative low impedance measuring circuit and a relative high impedance measuring circuit, wherein the measuring arrangement (43) is configured to measure the flame ionization current at the flame rod (13) when the measuring arrangement (43) is switched by the input definition circuit (34) to a relative low measuring impedance circuit, and wherein the measuring arrangement (43) is adapted to measure a thermionic voltage at the flame rod (13) when the measuring arrangement (43) is switched by the input definition circuit (34) to a relative high impedance measuring circuit.
