Siemens Flame Detectors - QRB4 Series
Yellow Flame Detector
Siemens Yellow Flame Detector - QRB4 Series
Features & Benefits:
• The QRB4 flame detectors are designed for the supervision of yellow-burning oil flames in connection with burner controls type LME7 (on request), LME8 (on request), LMO, LMV2 and LMV3. It is designed for frontal and lateral (90°) illumination. The maximum spectral sensitivity of the QRB4 is about 540 nm, thus giving full consideration to the maximum level of visible light radiation of yellow-burning oil flames. Since the QRB4 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.
