SWG 200 CEM Stationary gas analysis system for continuous process gas and emission monitoring

O2 NO NO2 SO2 CO2 CO CH4

Outstanding benefits:

  • Use of optimized NDIR technology with improved accuracy without zero point drifts
  • O₂ measurement with an electrochemical or a paramagnetic sensor
  • Automatic zero point in clean ambient air through separate calibration gas inlet
  • Automatic calibration for up to four gas cylinders
  • Double stage Peltier gas cooler with two automatic condensate pumps
  • Cold/dry gas extraction at a low flow volume of 1 l/min
SWG 200 CEM
Basic-Equipment
  • Stainless steel cabinet with monitored fan ventilation
  • Included dual heat exchanger Peltier gas cooler with two automatic condensate draining pumps
  • Efficient sample gas filtration using PTFE sintered particulate filter
  • Regulated sample gas pump with sample gas flow monitoring and alarm
  • Filtration of acid gases to protect the internal sample gas flow sensor
  • Solenoid valve for auto-zero with clean ambient air
  • Solenoid valve for calibration gas, with aluminium fine pressure regulator at cal. gas inlet port
  • Human machine interface with colour TFT display, keyboard and standard RS485 interface (Modbus RTU)
  • All password protected, intuitive software guided menu, with diagnosis software and logbook
  • Power supply analyser only 230Vac / 47-63Hz / 120W (110Vac power supply on request)
  • Total length of all heated sampling lines more than 60m, requires 3-phase power supply (L1 ; L2 ; L3 ; N ; PE)
  • Clean indoor mounting place, preferably air conditioned
  • Outdoor mounting place in clean, +5°C to 45°C ambient, with mandatory sun & rain protection (user scope)
