Manufacturer of Flame Rod Sensor in India Flame rod sensor we offer is accurate in sensing flame in Gas fired burners using flame detection & rectification technique. The Amplifier fitted provides a voltage for Flame Electrode and the flame electrode is immersed in flame to be sensed. Thus the current is generated by the flow of electrons is detected by the controller for presence of flame. The sensor senses the burning flame and is insensitive to visible light and refractory glows.
