    QRA2

    Siemens QRA2

    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.
