Siemens QRB1C-D048B40B flame sensor

Siemens QRB1C-D048B40B flame sensor is designed for monitoring yellow-flame liquid fuel combustion in conjunction with burners of type LAL..., LME7..., LMO..., LMV... and LOA... The maximum spectral sensitivity of the QRB1C-D048B40B sensor is approximately 600 nm, thus taking into account the maximum level of visible light emission from burning yellow-flame liquid fuel. This sensor is suitable for both frontal and side illumination (90°).
