SWG 200 CEM
Stationary gas analysis system for continuous process gas and emission monitoring
O2 NO NO2 SO2 CO2 CO N2O CH4 C3H8 H2S H2
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
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)
