CEM: Continuous Dust Concentration Emission Monitoring - Model: PE-SPMMS-C91 (LBS)

PE-SPMMS-C91 (LBS) is an on-line dust monitoring device using the mainstream technology of laser back-scattered light principle. PE-SPMMS-C91 (LBS) 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 Management System.

It is available for the monitoring and control of 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.

System is featured with, in-situ zeroing and span calibration, automatic gain control function & temperature compensation, smart appearance, easy installation, convenient disassembly without background light influence.

System consists of optical section, circuit and control section, calibrator and purge system. The laser beam (650 nm) comes across the detection area & produces scattered light after effect with dust particles. The back - scattered light crosses the lens converges into photosensitive detector. Analyzer circuit and control section converts light signal into signal output which is proportional to the dust concentration and obtains dust particles emission Concentration of Pollution.
