FIELD: power engineering.
SUBSTANCE: device to measure flame intensity in a burner, to which the first alternating signal is sent with the first predetermined fill factor, comprises a flame sensor, which generates ionisation current, proportional to flame intensity in the burner, and facilities to vary fill factor as a function of ionisation current, at the same time the first alternating signal and ionisation current are sent to the input of variation facilities, at the output the variation facility generates an alternating signal, having the second fill factor, which is a function of the ionisation current.
EFFECT: higher accuracy of measurement.
