Siemens Flame Detectors - QRB1, QRB3 Series
Photo Resistive Flame Detectors
Part/Code: QRB1, QRB3 Series
Siemens Photo Resistive Flame Detectors - QRB1, QRB3 Series
Features & Benefits:
• The QRB are designed for the supervision of yellow-burning oil flames in connection with burner controls type LAL, LME7, LMO, LMV and LOA. They are suited for frontal or lateral (90°) illumination. The maximum spectral sensitivity of the QRB is about 600 nm, thus giving full consideration 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.
