Dust Monitor with Laser Backward Scattering Measuring Technology, Applied for Continuous Monitoring of Pm Emission Concentrations of Various Pollution Sources

Product Description

PT-100 Dust monitor PT-100 is a self-developed online dust analysis product and a dust particle measuring device, adopting laser backward scattering measuring technology with imported core components. The PT-100 dust particle measuring device is mainly used for continuous monitoring of PM emission concentrations of various pollution sources. The PT-100 dust particle measuring device can be installed with CEMS continuous emission monitoring system, it also can be used separately or together with multiple dust monitors to form a dust monitoring network, sharing the same data collection and processing background.
Application
The PT-100 dust particle measuring device is widely applied in enterprises including thermal power, ferrous metallurgy, petrochemical industry, cement production, potting, waste incineration; flue gas emission monitoring in all kinds of power generating boiler, industrial kiln, and industrial boiler; monitoring and control in gas desulphurization and dust removal process.
Feature
• Supports online zero and span calibration and meets dust monitor principle
• Automatic gain control function and temperature compensation
• Convenient for installation, disassembly and cleaning with small and compact structure
• Eliminate the influence of background stray light
Working principle
The PT-100 dust particle measuring device consists of the optical part, circuit and signal processing part, calibrator and air curtain protection part.
The laser beam (650nm) emitted by semiconductor laser enters the stack and produces scattering light by interaction with dust particles. The backscattered light of the PT-100 dust particle measuring device enters the photosensitive detector through the convergence of the lens. The signal processing circuit converts the light signal into a standard signal in proportion to dust concentration and output, thus dust particle emission concentration of pollution source is obtained.
