Siemens QRB1B-A014U25B flame sensor

Siemens QRB1B-A014U25B flame sensor is a highly sensitive 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-A014U25B monitors the combustion process by detecting the light emission of the flame and transmitting a signal to the burner control. In case of flame loss, the sensor instantly initiates an emergency fuel shut-off, helping to prevent accidents, improve safety levels, and protect equipment from damage. The model features a compact design, high reliability, and resistance to long-term operational loads. The sensor is widely used in diesel and heavy oil burners of heating boilers, heat generators, and other equipment requiring precise flame monitoring and uninterrupted automation.
