Siemens QRC1A3.101C27 flame sensor

Siemens QRC1A3.101C27 flame sensor — a reliable photodetector for flame monitoring in gas and oil burners, designed for safe and stable operation of boiler and heat engineering equipment. The device is used in automatic combustion control systems and provides accurate flame presence monitoring during burner operation. The Siemens QRC1A3.101C27 detects the light emission of the flame and transmits a signal to the burner control unit. If the flame goes out, the sensor instantly initiates an emergency shutdown of the fuel supply, helping to prevent accidents, enhance equipment safety, and protect the system from damage. This model features high sensitivity, fast response, and stable operation even under intensive use. The sensor is widely used in gas, diesel, and dual-fuel burners of boilers, heat generators, and other heating equipment where reliable flame monitoring and uninterrupted automatic control are required.
