  • Flame detector self diagnostic system employing a modulated optical signal in composite with a flame detection signal
    Patent number: 5495112
    Abstract: A self diagnostic system for a flame detector. The system produces an optical determinant signal from an analog determinant signal that has a controllable amplitude and frequency. The system detects the optical determinant signal and the optical signal from the flame and processes both signals to thereby continuously monitor the flame while also continuously analyzing the operating status of the flame detector.
