The QRB... are designed for the supervision of yellow-burning oil flames in connection with burner controls type LAL..., LME7…,LMO..., LMV… and LOA…
Usage:
Photoresistive flame detectors for use with Landis & Staefa burner controls, for the supervision of oil flames in the visible light spectrum. The flame detectors are used primarily in connection with burner controls for small burners.
 * With this type of flame supervision, the radiation of oil flames in the visible light spectrum is used for generating the flame signal.
 * The light-sensitive element is a photoresistor.
 * When there is no light, the detector′s resistance is in the MΩrange.
 * The resistance drops as the intensity of illumination increases (kΩrange).
 * In contrast to the selenium photocell of the RAR... detectors, glowing firebrick in the  combustion chamber can be detected.
This model is widely used in various brands of fuel burners, including WEISHAUPT Germany, BALTUR Italy, ECOFLAM Italy, BENTONESweden and most of the domestic brand burners.
