Main features and advantages

The ABB AO2000 LS25 laser gas analyzer module,with its innovative TDLAS technology and modular design,provides excellent performance and significant advantages in the field of industrial gas monitoring.

Ultra high precision and selectivity:ABB AO2000 LS25 adopts advanced tunable diode laser absorption spectroscopy(TDLAS)technology,which can perform highly selective measurements for target gas molecules.This technology eliminates cross interference and provides extremely accurate concentration readings even in complex gas mixtures,ensuring the reliability and accuracy of measurement data.

In situ non-contact measurement:This analyzer supports in-situ measurement without the need to extract gas samples from the process pipeline for pre-processing.This means that the measurement is carried out directly in the pipeline or chimney,eliminating the time delay,maintenance requirements,and potential errors caused by the sampling system,thereby achieving faster response time and reducing operating costs.

Adaptability to harsh environments and explosion-proof safety:The transmitter and receiver units of AO2000 LS25 are designed to be sturdy,with an IP66 protection level,and can withstand harsh industrial environments.At the same time,it has obtained international explosion-proof certifications such as ATEX,IECEx,and CSA,suitable for safe use in potentially explosive environments(such as Zone 2),ensuring compliance and personnel safety in hazardous areas.

Wide measurement range and multi-component capability:ABB AO2000 LS25 is capable of measuring various gas components and supports a wide measurement range from extremely low concentrations(ppm level)to high concentrations(vol.%).This flexibility makes it suitable for various application scenarios,from trace gas detection to high concentration process gas analysis.

Modular design and easy integration:As part of the ABB Advance Optima AO2000 series,the AO2000 LS25 has a high degree of modularity and scalability.It can be freely combined with other analyzer modules(such as oxygen analyzer,photometer)to form customized analysis solutions.By connecting to the AO2000 central unit via Ethernet,remote operation,data access,and seamless integration into existing DCS/PLC systems have been achieved,simplifying system deployment and management.

Low maintenance and automatic calibration:The non-contact measurement principle of ABB AO2000 LS25 greatly reduces maintenance requirements,eliminating the need for frequent replacement of filter cartridges or cleaning of sampling pipelines.Many models also have automatic calibration function,eliminating the need for test gas cylinders,further simplifying daily operations and reducing ownership costs.
