Optical dust and opacity monitor

Optical transmission analyser to measure the opacity or dust concentration of sample gas. Can be calibrated to measure low and high dust concentrations. Compact and cost effective system to monitor the opacity or dust concentration in combustion and filter systems, ducts and warehouses.
Manufacturer: DURAG GROUP
  • In-situ measurement, continuous operation
  • Suitable for systems with variable gas speed
  • Allows calibration to measure the dust concentration in mg/m3
  • Measurement of opacity
  • Qualitative dust measurements for monitoring the function of filters
  • Can be used even at thick-walled stone / insulated ducts
  • Device is not in contact with sample gas
  • Long life LED
  • Hermetically sealed enclosures - no flue gas diffusion to optics or electronics unit
  • Optimized purge air provides long maintenance intervals
  • Easy installation, adjustment and maintenance
  • Parameterization is possible with or without a PC locally
  • Parameterization from external via RS-485 Modbus RTU possible

  • Sample gas type Air, flue gas, non flammable process gas
    Sample gas temperature Above due point,
    -20...200 °C (-4…392 °F) standard
    -20…600 °C (-4...1112 °F) option
    Inner duct pressure -50...+10 hPa (optional higher)
    Sample gas relative humidity 0...95% RF, non-condensing
    Stack/duct inner diameter 0.4…10 m (1.3…32.8 ft)
