Siemens Burners - AGR450240650 UV REPLACEMENT CELL, FOR QRA2M/QRA2M(1)/QRA10M.C/QRA51M/QRA53/QRA55

UV Replacement bulb for QRA2M/QRA2M(1)/QRA10MC/QRA51M/QRA53/QRA55

In HVAC installations UV flame detectors are designed for use with burner controls, for the control and monitoring of gas flames, yellow or blue-burning oil flames and for ignition spark proving. Trouble-free burner operation is ensured only when the intensity of the UV radiation of the detector is high enough for the detectors UV bulb to ignite during each half wave.

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, 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 boiler room illumination.

This replacement UV Bulb (Cell) is suitable for use with a wide range of Siemens Flame Detector models including QRA2M/QRA2M(1)/QRA10MC/QRA51M/QRA53/QRA55.
