Product Overview: The dual-infrared flame detector is a novel intelligent fire detection device. Utilizing high-performance dual-infrared sensing technology, the detector employs infrared sensors with different wavelengths and narrowband filtering. One sensor reflects the central wavelength of flame information, while the other monitors other infrared radiation in the environment. By combining the flickering characteristics of flames and performing computational analysis through high-speed microprocessors and technical algorithms, the radiation spectrum with flame characteristics is confirmed as a fire alarm. The detector exhibits strong anti-interference capabilities, effectively suppressing interference from sunlight, lightning, welding, thermal radiation, electromagnetic interference, and mechanical vibration. It provides rapid response and accurate identification of flame signals.
