Online dust monitoring device using the mainstream technology of laser back-scattered light principle with imported core components. BS-100 is mainly used for continuous monitoring of various sources emissions of particulate matter concentrations. It can be either equipped with CEMS or connected with dust monitoring network by a shared set of data acquisition and processing background.
It is available for the monitoring and control f soot emission, flue gas DeSOx and removal of dust for power generation boilers, industrial furnaces, industrial boilers in the thermal power, iron and steel metallurgy, petrochemical, chemical cement production, ceramics, waste incineration, etc.
Features
- In-situ Zeroing and span calibration.
- Automatic gain control function and temperature compensation
- Smart appearance, easy installation, convinient disassembly.
- Without background light influence.
- Infrared remote control
Measuring Principle
Series of BS dust monitors consist of optical parts, circuit and control sections, calibrator and purge system.
The laser beam [650 nm] comes across the detection area and produces scattered light after effect with dust particles. The back-scattered light crosses the lens coverage into photosensitive detector. Analyzer circuit and control section converts light signal into signal output which is propotional to the dust concentration and obtains dust particles emission concentration of pollution.
