Dust online monitoring system - dust detectorSystem Introduction

The general principle of a particle counter is laser scattering particle measurement. Firstly, use the built-in vacuum pump of the particle counter to0.1CFM(cubic feet)/Minutes)/2.83 LPM(Rising)/Inhale external air at a speed of minutes and let it pass in front of the laser light source inside the particle counter. In clean air, laser propagates in a straight line; But when light shines on dust, it will scatter; Therefore, the size of particles can be determined by measuring the amount of scattered light (scattered light), in other words, the number of particles can be determined by measuring the amount of laser scattering, and the size of dust can be determined by measuring the amount of scattered light. Even though the design principles of all manufacturers' products are the same, there are still differences in product performance, including sample speed, flow rate, detector sensitivity, particle size range, particle counting channel, durability of laser diodes or laser diodes, light source lifespan, and particle counter selection required for particle size measurement.
