Siemens QRB-3 Photocell Flame Sensor

Reliable flame detection for safe industrial combustion.

Siemens QRB-3 Photocell Flame Sensor provides real-time monitoring of liquid fuel flames, therefore eliminating fire and explosion risks in burner systems. In addition, it precisely detects the maximum visible light radiation from yellow flames. Moreover, it is specifically developed for intermittent operation liquid fuel burners.

This photocell lamp features spectral sensitivity peaking at approximately 600 nm, consequently isolating the yellow light spectrum with high accuracy. Furthermore, it reliably monitors light produced during hot fuel combustion while also detecting external light sources. As a result, it remains unaffected by factors such as heater area lighting or sunlight.
