IR Flame Detector IIIC IIC 50m Range Strong Electromagnetic Protection Design
1. Product Overview
This explosion-proof three-band infrared flame detector is engineered specifically for early fire warning across multi-fuel scenarios. It accurately detects flame signals from the combustion of various fuels—including oil, natural gas, and alcohols—and triggers timely alarms.
Featuring three high-sensitivity infrared sensors (each tuned to specific wavelengths) paired with a sapphire optical filter, it forms a high-efficiency flame detection system. Its proprietary spectral recognition mechanism ensures superior responsiveness to diverse fuel flames, enabling sharp capture of flame characteristic spectra. For signal processing, it employs advanced time-domain and frequency-domain analysis, combined with Fourier fuzzy algorithms and interference-source logic. This effectively filters out ambient light, industrial heat radiation, and other interference signals, drastically reducing false alarms. It operates reliably in both complex indoor industrial workshops and dynamic outdoor open-air environments.
The detector’s specialized fire signal processing algorithm and multi-sensor collaboration enhance detection sensitivity significantly. Even in harsh conditions—high temperatures, extreme cold, or high humidity—it maintains efficient, stable performance, ensuring robust fire safety for critical locations.

5.Indicator Lights
| Status |
Indicator light |
| Operation Indicator Light (Green) |
Always on |
| Alarm Confirmation Indicator Light (Red) |
It flashes for early warning and stays on when in alarm. |
| Fault Indicator Light (Blue) |
When a fault occurs, the blue light stays on (and the red light goes out). When the device is powered on, it flashes, indicating the self-checking and self-adaptive status. |
