      The detector’s UV cell is located behind a swiveling shutter at the front end of the detector tube which is flanged to the housing. A quartz-glass window protects the tube and the shutter against dirt. The detector’s housing accommodates a stepper motor to drive the shutter and the electronics to control the shutter. QRA5 series E and G differ with regard to the closing interval of the orifice. Using the AGG16.C adapter, this flame detectors can be mounted either directly on the burner, on a viewing tube or on a combustion chamber viewing hole
