Triple Infrared Explosion Proof Flame Detector IIC IIIC Certified Tunnel Compatible
Triple Infrared Explosion-Proof Flame Detector IIC IIIC Certified Tunnel Compatible
1.Product Overview
The JSY-F401-A is an explosion-proof multi-spectral flame detector designed for early fire detection across diverse fuel types.
Featuring three IR wavelength sensors and a sapphire optical filter, it delivers high sensitivity to flames from various fuels. Advanced time-frequency domain signal processing and Fourier fuzzy algorithms analyze collected data, minimizing false alarms by filtering ambient light/thermal radiation interference. Ideal for indoor/outdoor environments with challenging conditions, its robust design ensures reliable performance in extreme temperatures and humidity.
