Overview

Description

FD10-UVIR2 double IR & UV flame detector is a new type of intelligent fire detection equipment. The detectors uses two IR sensors and one UV ultraviolet sensor. Infrared sensors are with different wavelengths with narrow-band filtering. Ultraviolet sensor is with solar-blind band. One IR sensor and the UV sensor are used to reflect the center wavelength of the flame information. The other IR sensor is used to monitor other infrared radiation in the environment. Combining with the flicker characteristics of the flame, analyzing through high-speed microprocessors and calculating by mathematical algorithms, the radiation spectrum with flame characteristics is confirmed as a fire alarm.

The detector suppress the interference of sunlight, lightning, electric welding, thermal radiation, electromagnetic interference, mechanical vibration and other interference, thus achieving the rapid response and accurate identification of the flame signal.
