SIEMENS BURNER PHOTOCELL QRB1A BT PINK HEAD

Product Overview

The Siemens QRB1A is a photoresistive flame detector used with Siemens and Landis & Gyr burner controls to supervise oil flames in the visible light spectrum. Mounted at the burner and aimed toward the combustion chamber, it continuously monitors light levels and reports back to the control box, confirming that a genuine, stable flame is present and that no stray flame is lingering inside the chamber after shutdown. This constant supervision is a core safety function: if the photocell isn’t sensing correctly, the burner can cycle on and off unpredictably or shut down altogether as a protective measure. The QRB1A mounts securely via a flange and spring-loaded clamp for vibration-proof positioning, ensuring it stays correctly sited toward the flame through continuous operation. Compatible with a wide range of oil burners, it’s a trusted, dependable component for keeping combustion safety systems accurate and responsive.
