Weiguo - Model WD10-IR2 -Double IR Flame Detector
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.
- Using high-speed, low-consumption and high-performance 32-bit data processing chip
- Excellent resistance to radio frequency and electromagnetic interference
- Perfect patent algorithm, fast response, high stability, strong anti-false alarm ability
- Detection angle of 90°
- The longest detection distance can reach 50 meters
- Multi-level sensitivity settings to meet the needs of different occasions
- Magnetic bar adjusts sensitivity, no need opening the cover on site
- Explosion-proof design, suitable for hazardous areas in many types of industrial sites
It can be widely used in the city gas transmission and distribution pipeline, oil, petrochemical industry refineries, chemical plants, metallurgical industry, power industry and other places that may produce gas leakage.
