Overview
The Siemens QRB1A-A150B70A1 is a high-precision photoresistive flame detector designed for the supervision of yellow-burning oil flames. Engineered for use with Siemens burner controls, this sensor plays a critical role in safety by ensuring no stray flames exist in the combustion chamber during intermittent operation. The detector utilizes a specialized photoresistive element to monitor light levels in the visible spectrum, providing reliable feedback to the burner control system to maintain optimal performance and safety.
