Online Gas Analyzer Dust CEMS Continuous Particulate Matter Emission Monitoring System
>>Overview
AG-DUST07 Dust Monitor is designed for real-time and continuous measurement of particulate matter concentration in various pollution emission sources. It can be integrated into flue gas monitoring systems or used independently or in clusters to form a dust monitoring network with a shared front-end interface. The instrument is suitable for dust monitoring in power plants, steel mills, cement plants, as well as for process control in dust removal equipment and other powder engineering applications
>>Feature
• Adopting laser backscattering principle, it is immune to beam deviation caused by mechanical vibration of flue gas ducts and uneven temperature distribution leading to refractive index variations.
• Single-end installation, no optical alignment required.
• Features on-site display, allowing direct reading of dust concentration at the location.
• The modulated laser beam significantly enhances the system's anti-interference capability.
• The instrument is designed with a "tool-free" field installation concept, minimizing on-site installation complexity.
• Equipped with a standard (4-20)mA industrial current output for easy connectivity.
• The instrument has very low power consumption, approximately 3W.
• Standard settings typically apply to flue duct wall thicknesses less than 400mm and diameters larger than the instrument's nameplate indicates. Custom measurement zone sizes are available for special requirements. Adjustments can be made with the approval and guidance of maintenance personnel.
>>Principle
The optical part includes a laser light source, power control, photoelectric sensing, and scattered light receiving section. The 650nm laser beam is emitted at a slight angle into the emission source. The interaction between the laser beam and dust particles produces scattered light, which is then collected by the receiving system and converted into an electrical signal for processing. The circuit section performs functions such as photoelectric conversion, laser beam modulation, signal amplification, demodulation, light source power control, V/I conversion, and HMI display. The calibrator generates a stable optical signal for zero and span calibration of the instrument.
