Explosion-Proof UV/IR Flame Detector ⅡC&ⅢC IP67 Rated 24V
![]()
1.Product Overview
This explosion-proof multi-spectral flame detector provides advanced early warning for fires involving diverse fuel types.
Featuring triple IR sensors and a UV sensor with sapphire optical filtration, the device delivers superior flame detection across multiple fuel sources. Its proprietary signal processing combines time-frequency domain analysis with Fourier fuzzy algorithms to evaluate flame signatures while intelligently filtering out false triggers like ambient light and thermal radiation. The system's interference rejection logic ensures industry-leading false alarm immunity, making it ideal for challenging indoor/outdoor environments prone to nuisance alarms.
Enhanced by adaptive fire detection algorithms and multi-sensor fusion technology, the detector maintains high sensitivity and reliability in extreme industrial conditions including temperature extremes and high humidity.
