Explosion-Proof  Quad-Band Flame Detector Petrochemical Industry

1.Product Overview

The JSY-F401 is an explosion-proof multi-spectral flame detector designed for early fire detection across diverse fuel types. It features three infrared wavelength sensors, one ultraviolet sensor, and a sapphire optical filter, delivering exceptional responsiveness to combustion flames from various fuels.​

To minimize false alarms, the detector processes multi-signal data via proprietary time-domain/frequency-domain analysis and Fourier fuzzy algorithm. Combined with interference source logic for comprehensive judgment, it effectively eliminates interference from ambient light and thermal radiation—making it ideal for indoor and outdoor open environments with multiple false alarm

sources. Its specialized fire signal processing algorithm and multi-sensor technology significantly enhance sensitivity, enabling reliable operation in harsh industrial conditions such as extreme temperatures and high humidity.
