Filter on Flame Detection and Monitoring Device – With the continuous progress of society, the scale of cities is gradually expanding, and the living standards of the people are also gradually improving. However, in recent years, fire accidents in China have occurred frequently, especially in residential areas, showing a growing trend year by year.
Many domestic flame detector manufacturers integrate infrared and ultraviolet sensors into flame detection and monitoring devices to use the infrared and ultraviolet radiation emitted by flame combustion to judge the flame, and combine it with video monitoring to improve the accuracy of fire detection. However, the integration of infrared and ultraviolet sensors has also led to another issue, which is that although infrared has good penetration and can penetrate most glass and even metal, ultraviolet has poor penetration, and many glass can easily block it; In order to ensure the dust and water resistance of the flame detection and monitoring device, a certain protective structure must be installed on its shell. Therefore, it is very easy to affect the collection and analysis of the light sensor due to its own obstruction, thereby reducing the accuracy of flame detection and monitoring
The current solutions used for flame detection, monitoring, and monitoring filters mainly include:
UV/R ultraviolet/infrared dual probe flame detector
R/R double probe flame detector
The filters used for flame detectors produced by Hanzhong Borisun Optics covers the ultraviolet band (detecting ultraviolet wavelength of 185nm UV filter -260nm UV filter) and infrared band（ 900nm infrared bandpass filter and 4.3 μM narrowband filter), with accurate center wavelength and high transmittance in the narrowband passband, can effectively shield stray signals, improve equipment response speed and accuracy. Currently, the filters used in flame detectors have provided optical filter solutions for multiple flame detector manufacturers. Welcome to inquire
