The FD10 dual infrared flame detector is a kind of new-type intelligent fire detection equipment. This detector adopts the high-performance dual infrared sensing technology, and is provided with three infrared sensors with different wavelengths and narrow-band filtering. One sensor is used to reflect the central wavelength of the flame information, and the other is used to monitor other infrared radiation in the environment. Combined with the flicker characteristics of the flame, the radiation spectrum with flame characteristics can be identified as a fire alarm by means of the operational analysis with the high-speed microprocessor and technical algorithm. This detector is able to suppress the interferences such as sunlight, lightning, electric welding, thermal radiation, electromagnetic interference, mechanical vibration, etc., is provided with strong anti-interference capacity, and can quickly respond to and accurately identify the flame signal.
Be provided with high-speed, low-power, high-performance 32-bit high-precision data processing chip.
Have excellent resistance to radio frequency and electromagnetic interference and strong anti-interference performance.
Have perfect technical algorithms, high-speed response, high stability and strong ability in preventing false alarm.
Have a detection angle of up to 90°.
Have the maximum detection distance of up to 50m.
Have multiple-level sensitivity settings to meet the needs of different occasions.
The magnetic rod is used to adjust the sensitivity, without requiring the removal of the cap.
The explosion-proof design is applicable for dangerous areas on many types of industrial sites
