1. Product Overview
The Dust Monitoring System is designed for real-time and continuous online monitoring of dust concentration in industrial emission sources and ambient environments.
It can simultaneously measure dust concentration, gas temperature, pressure, and flow velocity, and output signals via standard industrial interfaces.
Based on laser back-scattering technology, the system offers high accuracy, strong stability and excellent anti-interference performance, making it ideal for harsh industrial ducts and outdoor environments with vibration and temperature fluctuations.
2. Monitoring Parameters and Output
Monitoring Parameters
Dust concentration
Gas temperature
Gas pressure
Gas flow velocity
Signal Output
4-channel 4–20 mA analog output
Compatible with environmental monitoring platforms, PLC and DCS systems
3. Working Principle
The system operates on the laser back-scattering principle:
A laser beam irradiates dust particles in the gas flow
Dust particles generate back-scattered light signals
The detector converts scattered light into electrical signals
The processed signals are converted into dust concentration values
This method is not affected by mechanical vibration or refractive index changes caused by uneven gas temperature, ensuring stable and reliable measurements.
