Abstract
Un oscillatore (3) pilota l'interruttore controllato (6) di un convertitore (2) con un segnale periodico impulsivo che ne determina tempi alterni di chiusura (Ton) lunghi e di apertura (Toff) brevi durante i quali il convertitore rispettivamente immagazzina l'energia prodotta da una termocoppia (23) in presenza di più a o fiamma e la fornisce con un valore più elevato alla restante circuiteria del rivelatore.Il convertitore comprende un LED (9) che indica la presenza della fiamma sotto controllo.
