Display and control

Display and control unit and electronics module in the door of the analyzer cabinet or of the separate electrical distribution

Data transmission

Modbus interface for transmission of measured values and status signals as well as analog input, digital input, and digital output signals

The analyzers of the AO2000 System are able to measure up to six sample components simultaneously. The following standardized variants are available:

Applications	Components
Emission Monitoring
according 2001/80/EG and 2000/76/EG QAL3 monitoring software tool included!	CO, NO, SO2, NOx, N2O, NO2, O2
Process Gas Measurement
The spectrum of these applications can be extremly wide and highly complex in the various industrial sectors.	CO, CO2, NO, NOx, N2O, SO2, CH4, VOC, O2
A great variety of sample gas compositions and difficult marginal conditions such as high or changing pressures and temperatures make exacting demands on the measuring technology. The AO2000 System can be optimally engineered for these measuring tasks in close collaboration with our customers.
Typical areas of application: Industrial gas production Chemical plants, e. g. nitric acid Iron and steel production Steam generators Blast furnace gas analysis Power stations Paper production Sugar production
Cement Applications
Calciner Gas Exit T<900°C	CO, CO2, NO, NOx, CH4, SO2, O2
Wet Kiln Exit T<300°C	CO, CO2, NO, SO2, O2
ESP Preheater T90 <10s	CO, NO, SO2, O2
