The infrared photoelectric eye QRI2 detects infrared, used to detect yellow flames, that is, to detect infrared in flames, and can be used for fuel flame safety detection. Used in conjunction with Siemens program controllers for large burners, it can operate continuously or intermittently. Falling or hitting can affect safety functions. Such detector units cannot operate, even if their appearance appears to be damaged at all
