DM-100 Dust Particle Monitor utilizes the laser backscatter principle to measure particle concentration. The optical component includes a laser light source, power control, photoelectric sensors, and a scattered light reception section.
The highly stable laser emitted by the laser source is collimated and then directed enter into the flue pipe. When the laser beam encounters particle , it generates backscattered light. This scattered light is focused by a lens and then detected by a photoelectric detector. After the photoelectric signal conversion, the scattered light signal is transformed into an electrical signal proportional to the concentration of particle. Through specific algorithms, the output is the concentration value of the particle.
