Flame-safeguard controls and burner management systems are designed for industrial and commercial applications. Features of its Model 95 Series include complex flame-analysis methods such as selectivity of spectral response in the ultraviolet or infrared region, or both. Other features include adjustable sensitivity to flame-signal strength to determine a flame-on vs. flame-off condition and flicker-frequency selection to discriminate from flame to flame. The Paragon flame scanner can optically detect maximum flame temperature in addition to flame detection. The flame safeguards can be found in power plants, pulp and paper mills, petrochemical facilities and food processing plants.
