1. Product Overview
This explosion-proof triple-band flame detector employs innovative multi-spectral detection technology, leveraging the synergistic operation of two infrared sensors (IR1/IR2) and one ultraviolet sensor (UV) to form a three-band flame identification matrix, significantly enhancing detection accuracy. Equipped with a sapphire optical filter and Fourier fuzzy algorithm, it precisely identifies the spectral characteristics of flames from various fuel types. Its unique time-domain and frequency-domain dual analysis technology, combined with dynamic environmental compensation algorithms, effectively suppresses interference from thermal radiation and ambient light, reducing false alarm rates by over 90% compared to conventional detectors.
The product also demonstrates outstanding environmental adaptability, operating within a broad temperature range of -10°C to +55°C, and features an IP67 protection rating and a corrosion-resistant design, ensuring stable performance even in harsh industrial environments such as oil refineries and chemical plants. Through multi-sensor data fusion and intelligent algorithm processing, this detector achieves significant breakthroughs in flame recognition accuracy and response speed (nanosecond-level), providing reliable protection for industrial safety applications.

5.Indicator Lights
The JSY-F301-B flame detector is equipped with three status indicator lights, which are used to indicate its working status.
| Status |
Indicator light |
| Operation Indicator Light (Green) |
Always on |
| Alarm Confirmation Indicator Light (Red) |
It blinks for early warning and is always on for an alarm. |
| Fault Indicator Light (Blue) |
When a fault occurs, the blue light is always on (and the red light goes out). When the device is powered on, it blinks to show the self-checking and self-adaptive status. |
