Siemens QRB1B-D042B20B flame sensor

Siemens QRB1B-D042B20B flame sensor is a reliable photodetector for monitoring the presence of flame in liquid fuel burners. The device is intended for use in automatic combustion control systems and ensures safe and stable operation of boiler, heating and thermal equipment. Siemens QRB1B-D042B20B monitors the presence of flame during burner operation 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, stable operation and reliability during long-term use. The sensor is widely used in diesel and fuel oil burners of boilers, heat generators and other heating equipment where precise control of the combustion process and uninterrupted operation of automation are required.
