Application for Flame Relay IFW 15 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.
Application for Flame Relay IFW 15 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.
