Tünel üç Bant Uzak Kızılötesi alev Dedektörü (BK51/IR3/S)

According to the features of fires in the tunnel and the technical advantages of the triple-wavelength infrared flame detector, Xi'an Bokang Electronics Co., Ltd successfully develops the triple-wavelength infrared flame detector specially for the detection of fire in the tunnel. Besides the technical advantages of the common triple-wavelength infrared flame detector, the detector also has the following unique advantages: 1. Duel-technology detection with a detection angle of 180 DEG, no detection angle adjustment needed during installation, no blind angle left in the detection of fire in the tunnel; 2, built-in lightning protective measures, which can effectively prevent the interference on the circuit caused by lightning and ensure the reliable and stable operation of the system in a zone full of mountains and lightning; 3, being hung on the side wall 2.5~3.5m from the ground, which ensures the detection effect free of the impact of barriers like automobiles and brings about simple and convenient installation; 4, ensuring effective range of detection in case of 50% of the monitoring window polluted, which greatly reduces maintenance cycle and cost; 5, unique dustproof waterproof pan seal structure with the protective grade of IP65, which enables the detector to be free of the impact of dust and oil pollution in the tunnel and fundamentally ensures the reliable and stable operation of the detector.
