YX-CEMS Continuous Emission Monitoring System
Overview of Product
YX-CEMS is a new generation of flue gas monitoring system. The world-advanced technology is used to measure concentration of flue dust by adopting laser backward scattering method. Hot pipe is adopted for complete sampling and non-dispersive infrared adsorption method (NDIR) is adopted to measure concentration of pollutant in flue gas, including SO2, NO, CO and CO2. Pitot tube, pressure sensor, temperature sensor, humidity sensor and oxygen analyzer of zirconium oxide are used to measure parameters of flue gas, and industrial personal computer, PLC and software system independently developed by our company are used to collect and process data, conduct real-time monitoring, generate charts and statements and control operations of the system. The system has the characteristics of high measurement precision, remote-control interlinking monitoring, stable and reliable running and high performance-price ratio.
