WD10-IR2

WD10-IR2 double IR flame detector is a new type of intelligent fire detection equipment. The detectors uses 2 infrared sensors with different wavelengths with narrow-band filtering. One sensor is used to reflect the center wavelength of the flame information. The other 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.

Response spectrum range 4.3μm, 5.0μm
Detection object Flame
Detection method Real-time sampling of optical path
