Product Overview: The three-infrared flame detector is a new type of intelligent fire detection device. Utilizing multi-infrared sensing technology (MIR), the detector employs three infrared sensors with narrow-band filtering and different wavelengths. One sensor reflects the central wavelength of flame information, while the other two monitor other infrared radiation in the environment. By combining the flickering characteristics of flames and analyzing 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 also provides rapid response and accurate identification of flame signals.
