Flame detection systems are advanced sensors developed to identify the presence of open flames or fires by monitoring optical radiation in the ultraviolet (UV), infrared (IR), or a combination of these spectral ranges. Manufacturers calibrate them to specific spectral sensitivity ranges and time-response thresholds, allowing for reliable operation in a variety of industrial and commercial environments. These detectors offer fast, automatic detection and are particularly effective in high-risk areas where explosive or flammable materials are present.
