Abstract
Se describe en la presente un circuito (10) para producir señalesrepresentativas de cuando menos, dos niveles de corriente flama. Elcircuito (10) dos electrodos (12,14) situados en una flama (16), en dondeun potencial de voltaje se establece entre los electrodos (12,14), y elflujo de corriente se mide entre ellos (corriente de flama). El circuito(10) una parte de amplificación (24,42) para amplificar la corriente deflama y aplicar una señal a un microprocesador (38). El microprocesador(38) muestrea la señal y da salida a una señal representativa del nivel decorriente para flama.
