QRA2 / QRA2M UV flame detector is ultraviolet flame sensing component used for gas burners, compatible replacement for original flame photocell.

Model: QRA2, QRA2M. This UV probe captures ultraviolet radiation generated by gas flame, transmits flame signal to burner controller to realize continuous flame monitoring. It detects flame existence rapidly; once flame loss occurs, it sends feedback signal to trigger safety interlock and cut off gas supply, prevent gas accumulation and explosion risk. Widely matched with industrial gas burners equipped with corresponding combustion program controllers, applicable on steam boilers, hot water boilers, thermal oil furnaces and heating kilns.

Applicable fuel: Natural gas, LPG and other gaseous fuels with ultraviolet flame radiation.

Installation & Safety Instructions

Confirm controller base model before purchase, ensure compatibility with QRA2 / QRA2M detector.
Power off burner system before installation and wiring work.
Install the probe facing flame, keep sight path unobstructed without dust, smoke or obstruction.
Avoid direct sunlight or strong external light shining onto UV probe to prevent false alarm.
Regularly clean lens surface dust and carbon deposit to guarantee detection sensitivity.
Replace immediately if signal instability, slow response or lens aging appears.
