Common questions on this part
The QRB3 is specifically designed for Siemens LAL1, LAL2, LFL1, LOK16, and LAE1 industrial control boxes.
It detects visible yellow light (400 to 700 nm) produced by oil and light fuel combustion.
QRB3 features a heavy-duty metal housing and electrical characteristics matched for industrial LAL/LFL controllers, whereas QRB1 fits smaller LMO/LME series.
Yes, the metal shell protects the internal CdS cell from high ambient temperatures near burner blast tubes.
Remove the sensor from the sight tube and wipe the glass front gently with a clean dry cloth.
Manufactured by Siemens Building Technologies in Germany.
Yes, STARNEX maintains counter stock of Siemens QRB3 photocells at our Nairobi Industrial Area warehouse.
It includes 500 mm heat-resistant flexible connection leads.
Operates reliably between -20°C and +60°C.
Yes, provided the flame produces visible yellow light and the control box is Siemens LAL or LFL.
