Siemens „QRI2A2.B180B“-Flammensensor

Siemens QRI2A2.B180B flame sensor — a high-precision infrared sensor for monitoring flame presence in industrial burners. The device is designed for use in automatic combustion control systems and ensures safe operation of gas, oil, and dual-fuel thermal equipment. Siemens QRI2A2.B180B uses an infrared flame monitoring principle, allowing accurate detection of flame presence and stability even under difficult operating conditions. The sensor transmits a signal to the burner control and, in case of flame loss, initiates an emergency shutdown of fuel supply, helping to prevent hazardous situations and enhance industrial safety. The model features high sensitivity, resistance to external interference, and reliable operation under long-term use. The sensor is widely used in industrial boilers, furnaces, heat generators, dryers, and other equipment requiring precise and stable combustion monitoring.
