Siemens QRB1B-A018B40B flame sensor

Siemens QRB1B-A018B40B flame sensor is a compact and reliable photodetector for monitoring flame presence in oil-fired burners. The device is designed for use in automatic combustion control systems and ensures safe, stable, and efficient operation of boiler and heat engineering equipment. Siemens QRB1B-A018B40B monitors flame presence during burner operation and transmits a signal to the burner control. If the flame goes out, the sensor instantly initiates an emergency fuel shut-off, helping to prevent accidents, improve operational safety, and protect the system from damage. The model features high sensitivity, stable operation, and reliability over long-term use. The sensor is widely used in diesel and heavy oil burners of heating boilers, heat generators, and other heat engineering equipment requiring precise combustion control and uninterrupted automation.
