CNEX Triple-Band UV IR Flame Detector 3.8um 4.4um185-260nm IIIC IIC
1. Product Overview
This explosion-proof flame detector is engineered for harsh industrial settings, boasting UV + dual-IR (IR1/IR2) triple-band sensors. Fitted with a sapphire optical filter for full-spectrum detection, its multi-spectral fusion technology precisely identifies flames from fuels such as n-heptane, methane, diesel, and kerosene.
By targeting UV ionization and IR thermal radiation released during combustion, it delivers early warnings within ≤15 seconds—outperforming conventional single-band detectors.

5.Indicator Lights
The JSY-F301 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. |
