Siemens QRB1B-A050B70A – czujnik płomienia

Siemens QRB1B-A050B70A 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 precise monitoring of flame presence during burner operation. Siemens QRB1B-A050B70A detects the light emission of the flame and transmits a signal to the burner control. If the flame goes out, the sensor immediately initiates an emergency shutdown of fuel supply, helping to prevent accidents, increase operational safety, and protect equipment from damage. The model features high sensitivity, stable operation, and reliability under long-term use. The sensor is widely used in diesel and fuel oil burners of heating boilers, heat generators, and other thermal equipment where reliable combustion monitoring and uninterrupted operation of automation are required.
