The FL3101H is an Ultraviolet-only flame detector designed to detect fires and provide alarm outputs directly from the detector while maintaining false alarm immunity. It detects in the ultraviolet (UV) spectral range for optimized speed of response. Configurations with dual Modbus and HART are available. Modbus and HART data can be used for predictive maintenance. The flame detector's electronics are integral within its explosion-proof housing, allowing detector information to be processed at the point of detection.
