Advantages and Features
The ABB AO2000 LS25 uses TDLAS technology to provide selective gas measurement that is largely immune to cross-interference from other gas components, ensuring accurate results in complex process streams. The AO2000 LS25 offers fast response times, enabling real-time process control and emissions monitoring. Its non-contact optical measurement principle reduces sensitivity to probe contamination and minimizes maintenance compared with extractive analyzers. The module integrates with the AO2000 platform for unified operation, diagnostics, and data communication, and the AO2000 LS25 provides stable, low-drift measurement that reduces calibration frequency. ABB’s application engineering and service network support commissioning and lifecycle management of the analyzer system.
Application Cases and Fields
The ABB AO2000 LS25 is commonly applied in:
-
Power plant flue gas emissions monitoring (NOx, SO2, CO, O2, moisture)
-
Cement kiln and preheater gas analysis
-
Chemical and petrochemical process gas measurement
-
Ammonia slip monitoring in DeNOx systems
-
Hydrogen chloride and moisture monitoring in incineration and process applications
In these applications, the AO2000 LS25 provides continuous, selective gas concentration data for process optimization, emissions compliance, and safety monitoring.
Comparison with Competing Products
Compared with conventional extractive gas analyzers, the ABB AO2000 LS25 offers faster response, lower maintenance, and reduced sensitivity to sample conditioning problems, thanks to its in-situ TDLAS measurement principle. Competing laser analyzers may offer similar measurement capability but differ in integration, service support, and platform compatibility; the AO2000 LS25 benefits from native AO2000 system integration. Against electrochemical or paramagnetic analyzers, the AO2000 LS25 provides superior selectivity and drift performance. For continuous process and emissions monitoring where reliability and low maintenance are priorities, the ABB AO2000 LS25 remains a strong, field-proven choice.
Selection Suggestions and Precautions
-
Confirm the gas species, concentration range, and process conditions (temperature, pressure, dust loading) match the AO2000 LS25 configuration.
-
Verify the installation mode (in-situ vs. extractive) and probe/flange requirements for the specific stack or duct.
-
Plan integration with the AO2000 system and plant control network, including signal mapping and alarm configuration.
-
Follow ABB installation and commissioning manuals for optical alignment, purging, and calibration; observe laser safety precautions.
-
Procure the ABB AO2000 LS25 through authorized channels to ensure authenticity, correct configuration, and warranty coverage.
-
Maintain spare optical and electronic components given the criticality of continuous emissions monitoring.
-
Perform regular validation with certified test gases and verify measurement performance against reference methods as required by regulations.
