Common questions on this part
The QRA2 detects shortwave ultraviolet (UV) radiation (190 to 270 nm) emitted by gas, oil, and dual-fuel flames.
No, the QRA2 UV tube is blind to daylight, incandescent light, and red-hot refractory bricks, preventing false flame signals.
Works with Siemens LFL1, LFE1, LFA1, LGB22, LME7, and LMG22 control boxes.
It features an IP54 dust and splash-proof die-cast aluminium housing.
Yes, like all UV detector tubes, the internal gas tube has an operational life of ~10,000 hours and should be tested annually.
It mounts onto a sight tube aimed directly at the flame root using its integral clamping flange.
Manufactured by Siemens Building Technologies in Germany.
Yes, it is the primary UV flame scanner used on commercial LPG, natural gas, and dual-fuel burners in Kenya.
Yes, STARNEX holds dedicated counter stock of Siemens QRA2 detectors in Nairobi Industrial Area.
Operates reliably from -20°C to +60°C (-4°F to +140°F).
