ABB
The AO2000 series offers analyzer modules using various measurement principles which are suitable for practically any processing task, including:

h Infrared analyzer modules
h Process photometers
h Thermal conductivity analyzer modules
h Oxygen analyzer modules
h Flame ionization detectors
h Laser analyzer modules


AO2000 SERIES - LS25

The LS25 laser analyzer (laser in-situ or NIR-laser) selectively measures the concentration of up to two (2) sample components.  The laser operates according to the principle of single-line spectroscopy.  For measurement purposes, a single absorption line is selected from the gas to be measured in the near infrared spectral range, at which no cross-sensitivity from other gases occurs.  The absorption line is scanned and the receiver located opposite detects the absorption caused by the sample gas and calculates the gas concentration from this.

Typical Applications

h Emission monitoring
h Combustion control
h Process monitoring and analysis in the chemical industry, steel and iron
  manufacture, power industry and glass manufacture
h Control of DeNOx installations

Sample Components - Smallest Measuring Ranges (examples)

- O2 0...1 Vol.%, 10 bar, 1500oC
