Product Overview: The dual-infrared and one-ultraviolet flame detector is a novel intelligent fire detection device. The detector utilizes high-performance dual-infrared sensing technology and ultraviolet detection technology, employing infrared sensors with different wavelengths and narrowband filtering, as well as ultraviolet flame sensors that are blind to sunlight. One of the three sensors, one infrared and one ultraviolet, is used to respond to the central wavelengths of flame information in different bands, while the other infrared sensor monitors other infrared radiation in the environment. By combining the flickering characteristics of flames and analyzing through high-speed microprocessors and technical algorithms, radiation spectra with flame characteristics are confirmed as fire alarms. The ultraviolet flame sensing device effectively suppresses interference from sunlight, enabling rapid response and accurate identification of flame signals. Additionally, this detector can be used for dual-infrared detection or single-ultraviolet detection, and can perform both infrared and ultraviolet detection simultaneously.
