Online Dust Detector Working Principle
Our online dust detector uses the principle of laser scattering.
Laser scattering method: measures the degree of scattering of light by particles in the air.
When light passes through air containing particles, the particles scatter the light. The detector calculates the dust concentration by measuring the intensity of the scattered light.
Online Dust Detectors can be placed directly in environments with high dust concentrations to detect dust concentrations in the environment in real time. You can set corresponding high and low alarm values. Detect the dust content in the environment, support linkage with fans and exhaust fans, reduce dust concentration in the environment in real time, and protect personnel safety in production.
Sino-Inst’s Online Dust Detectors are suitable for real-time and accurate detection of dust concentration and leakage in various environments. If you need dust monitoring, please feel free to contact our sales engineers!
