Flame control with flame rod
An alternating voltage is applied between the flame rod, which projects into the flame, and the grounded burner. As soon as the flame is established a small current flows through it and is rectified by the flame. The electronic amplifying stage detects only this direct current signal which, after amplification, is used to energize a relay. A flame cannot be simulated.
Flame control with UV-detector
The UV-detector mainly consists of a tube which is sensitive to light and of electronic components. The tube responds to the ultra violet (UV) radiation from a gas flame, it does not react to sunlight and light from filament lamps.
