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 signal.

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.

Higher ambient temperatures reduce considerably the cell's life.
