With this type of flame supervision, the UV radiation emitted by gas or oil flames is
used to generate the flame signal.
The radiation detector is a UV-sensitive cell with 2 electrodes, which ignite when illuminated with radiation in the 190...270 nm range of the spectrum, thereby triggering a
current in the flame detector circuit.
The UV cell does not respond to glowing firebrick in the combustion chamber or to
daylight.
