The flame detectors are used for the supervision of gas flames, yellow- or blue-burning oil flames and for ignition spark proving.
With this type of flame supervision, the UV radiation emitted by gas or oil flames is used to generate the flame **.
The radiation detector consists of 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, daylight or light from the boiler room illumination.
