The Siemens QRA55.E27 is a self-checking ultraviolet flame detector designed for continuous operation in burner control systems. It is used with Siemens LGK16 and LGI16 automatic burner controls for monitoring gas flames, yellow-burning or blue-burning oil flames, and spark ignition proving. The detector features a UV-sensitive cell with two electrodes that respond to radiation in the 190-270 nm wavelength range, triggering a current in the flame detector circuit when exposed to flame radiation. The UV cell does not respond to glowing firebrick, daylight, or artificial lighting. Equipped with normal sensitivity and a 69 mm sensor tube, the detector is supplied complete with a mounting clamp and requires a separate AGM19 connecting cable for installation. The housing provides IP65 protection against dust and water ingress, making it suitable for industrial burner applications.
