Photoresistive
Flame Detectors
Photoresistive detectors for use with Siemens burner controls, for the supervi-
sion of oil flames in the visible light spectrum.
The QRB... are used primarily in connection with oil burner controls in intermit-
tent operation.
The QRB... and this Data Sheet are intended for use by OEMs which integrate the
flame detectors in their products.
The QRB... flame detectors are designed for the supervision of yellow-burning oil
flames in connection with burner controls type LAL..., LOA..., LMO... and LMV...
They are suited for frontal or lateral (90°) illumination.
The maximum spectral sensitivity of the QRB... is about 600 nm, thus giving full con-
sideration to the maximum level of visible light radiation of yellow-burning oil flames.
Since the QRB... also acquires certain parts of the radiation spectrum of other light
sources (boiler room lighting, solar radiation, etc.), the standard regulations regarding
safety in connection with extraneous light still apply.
