Ex UV IR Flame Detector Brewing Industry Multiple Combustibles
1.Product Overview
This explosion-proof multi-spectral flame detector adopts red-ultraviolet hybrid detection technology, integrating 2 infrared wavelength sensors (IR1/IR2) and 1 ultraviolet sensor (UV), and is equipped with a sapphire optical filter.
Through cross-validation of data from the three sensors, it achieves nanosecond-level response to early flame signals, with detection accuracy increased by over 70% compared to single-spectral detectors. It is equipped with a time-domain and frequency-domain dual-signal processing system and Fourier fuzzy algorithm to intelligently filter interference such as ambient light and thermal body radiation, reducing the false alarm rate by 90% compared to traditional products. Relying on multi-sensor collaboration and adaptive algorithms, it can operate stably in extreme environments such as -10°C to 55°C and humidity ≤95% RH without condensation, suitable for early fire warning and safety protection in multiple scenarios such as petrochemical plants, nuclear power plants, and chip factories.
2.Product Features

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. |
