Siemens Combustion QRI2B2.B180B1 Flame Detector 320788-704 the Trane MFL0806 Muffler isThe Siemens QRI2B2. B180B1 is a high sensitivity infrared flame detector designed for the supervision of gas, oil, or coal flames in large scale industrial or commercial burner systems. Engineered for lateral (side viewing) illumination, it features a 90 degree light entry path, making it the standard choice for specific burner mounting configurations where frontal line of sight is obstructed. This self checking sensor operates within a 1 to 3 m
