Brahma UV1 UV2 UV Cell Flame Sensor

Brahma UV1 flame detectors sensors are used for flame detection in gas and mixed fuel (gas and oil) burners. UV phototubes consist of a glass bulb filled with gas, containing two electrodes suitably shaped. When supplying both electrodes with AC voltage, if an ultraviolet electromagnetic radiation (range from 190 to 290 nm) hits the phototube, the electrons,emitted by the negative biased electrode and captured by the positive biased one, start an ionization process leading to the generation of an electric discharge and hence to the production of electric current. UV phototubes exploit ultra-violet radiation emitted by the light generated by the flame; they are especially suitable for appliances in which very dissimilar fuels (e.g. liquid and gaseous fuels) are used.
