ABB AO2000-LS25 is a laser analyzer.Here is a detailed introduction to it:

1.Product Overview

ABB AO2000-LS25 is a precision instrument using the most advanced electronic and laser technology.It is mainly used for continuous on-site monitoring of gases in chimneys,ducts,process rooms or similar places.It is based on the principle of tunable diode laser absorption spectroscopy(TDLAS)and measures the average gas concentration along the line of sight path through a transmitter/receiver configuration.

2.Technical Principle

The measurement principle of the analyzer is infrared single-line absorption spectroscopy,which uses the characteristic that each gas has a different absorption line at a specific wavelength for measurement.The laser wavelength scans the selected gas absorption lines to be measured,which are carefully selected to avoid cross-interference from other(background)gases.The detected light intensity changes with the change of the laser wavelength,and the target gas molecules absorb the laser wavelength in the optical path between the transmitter and the receiver.In order to improve the sensitivity,the analyzer also uses wavelength modulation technology.

3.Product composition

The ABB AO2000-LS25 analyzer consists of three independent units:

Transmitter unit with purification function:includes laser module,temperature-stabilized diode laser,collimating optical lens group and main electronic equipment,which are installed in a coated aluminum box.

Receiver unit with purification function:contains a focusing lens,photodetector and receiver electronic components,which are installed in a coated aluminum box.

Power supply unit:provides the required power for the analyzer.

4.Product features

High precision:adopts advanced laser technology and wavelength modulation technology to achieve high-precision measurement.

High reliability:The environmental protection level of both the transmitter and receiver is IP66,and the pressure resistance of the standard optical window can reach up to 5 bar(absolute pressure),ensuring stable operation even in harsh environments.

Easy to install and maintain:The installation method of the analyzer is simple and reliable,and the purification device can prevent dust and other contaminants from depositing on the optical window,reducing maintenance costs.

Multi-function display:The display(LCD)can continuously display gas concentration,laser beam transmission and instrument status,which is convenient for users to monitor and analyze in real time.

Rich communication interfaces:RS-232 port is provided for direct serial communication with PC,and the optional Ethernet board provides TCP/IP communication through local area network(LAN),which is convenient for users to conduct remote monitoring and data transmission.

5.Application fields

ABB AO2000-LS25 laser analyzer is widely used for gas monitoring in the fields of power,chemical,petroleum,environmental protection,etc.In power plants,it can be used to monitor the gas concentration of chimney emissions;in the chemical and petroleum industries,it can be used to monitor the concentration of harmful gases in pipelines and process rooms;in the field of environmental protection,it can be used to monitor the concentration of pollutants in the atmosphere,etc.

In summary,ABB AO2000-LS25 is a high-precision,high-reliability,easy-to-install and maintain laser analyzer with a wide range of applications and important application value.
