مستشعر اللهب Siemens QRB1B-D022X20B

Siemens QRB1B-D022X20B flame sensor is a reliable photodetector for flame monitoring in liquid fuel burners, designed for safe and stable operation of boiler and thermal equipment. The device is used in automatic combustion control systems and provides accurate monitoring of flame presence during burner operation. Siemens QRB1B-D022X20B detects the light emission of the flame and transmits a signal to the burner control. When the flame disappears, the sensor instantly initiates an emergency shutdown of fuel supply, which helps prevent emergency situations, protect equipment and increase the safety of the heating system. The model is characterized by high sensitivity, resistance to operational loads and stable operation over a long period. The sensor is widely used in diesel and fuel oil burners of heating boilers, heat generators and other thermal equipment where reliable combustion process monitoring and uninterrupted automation operation are required.
