Siemens QRC1A2.103C27 flame sensor

Siemens QRC1A2.103C27 flame sensor — a highly sensitive photodetector for monitoring flame presence in gas and oil 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. The Siemens QRC1A2.103C27 monitors the combustion process by detecting the light emission of the flame and transmitting 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, protect equipment, and enhance the safety of the heating system. This model features high sensitivity, fast response time, and reliable operation over long service life. The sensor is widely used in gas, diesel, and dual-fuel burners of boilers, heat generators, and other equipment where precise flame monitoring and uninterrupted automatic control are required.
