The QRA2 is a UV (ultraviolet) flame detector used on burners and combustion systems to sense the presence of flame and ensure safe operation:
✔ Detects ultraviolet radiation from gas or oil flames (190–270 nm range).
✔ Works with burner control units — it tells the controller whether a flame is actually present once ignition occurs.
✔ Helps confirm ignition and is a critical part of safety supervision on burners.
✔ Usually mounted directly on the burner assembly.

A Burner Flame Sensor is a safety device used in oil or gas burners to detect the presence of a flame in the combustion chamber. It ensures that the fuel being supplied is actually burning. If no flame is detected, the burner’s control system shuts off the fuel supply to prevent unburned fuel from accumulating, which could cause fire or explosion hazards.
