High precision: Thanks to advanced infrared technology, AZ20/112112221112E/STD can measure the concentration of various gas components with high precision.
Wide measurement range: This analyzer has a wide measurement range, which can measure both low concentration and high concentration gases, meeting the needs of different application scenarios.
Multi gas measurement: capable of measuring various gas components, providing users with comprehensive gas analysis data.
Automatic calibration: The instrument has an automatic calibration function, which can automatically adjust the measurement parameters to ensure the accuracy and stability of the measurement.
Easy to operate: Designed with a user-friendly interface, the operation is simple and intuitive, making it easy for users to quickly get started and take measurements.
Software and firmware:
The software of the analyzer consists of two programs: device firmware (hidden from the user and integrated into the CPU electronic device) and Windows running on a standard PC connected via RS-232 connection ® Service program. The device firmware performs all necessary calculations and self-monitoring tasks, while the service program allows communication with the device during installation, service, and calibration.
Product composition
AZ20/112112221112E/STD mainly consists of three independent units: a transmitter unit with purification function, a receiving unit with purification function, and a power supply device. The transmitter unit includes a laser module, a temperature stable diode laser, a collimating optical lens group, and main electronic equipment, all of which are installed in a coated aluminum box. The environmental protection level of both the transmitter and receiver is IP66, and the standard optical window can withstand a maximum pressure of 5 bar (absolute pressure).
Three independent units: The analyzer consists of a transmitter unit with purging function, a receiver unit with purging function, and a power supply unit. Each unit plays a crucial role in the measurement process, contributing to the overall functionality and performance of the system.
Measurement principle:AZ20/112112221112E/STD uses absorption line method to measure the concentration of specific gases using laser. The laser is transmitted along the path where the gas sample is located, and the receiver detects the light absorbed by the gas molecules. Through this detection, the gas concentration can be calculated.
Installation variants: This analyzer has two variants: universal and explosion-proof, which can meet different environmental conditions and safety requirements. This versatility makes it suitable for various industrial environments.
Troubleshooting and error handling: The device displays potential issues clearly on its LCD screen, including errors related to low transmission, laser alignment, temperature and pressure readings, and power failures. These error messages help to quickly diagnose and solve problems, ensuring uninterrupted operation.
Ethernet connection: AZ20/112112221112E/STD supports Ethernet connection, making it easy to integrate into modern industrial networks. This feature enables remote monitoring and control, thereby improving operational efficiency.
Error handling and maintenance:
LCD display screen: The basic status information of the instrument is displayed on the LCD installed on the transmitter/host. This includes error messages and maintenance requests, which help to quickly identify and resolve issues.
Troubleshooting: The manual provides detailed information on common faults such as low transmission rate, laser alignment errors, and issues with reading temperature or pressure inputs, and provides measures to be taken. This guide helps to effectively solve problems and minimize downtime to the greatest extent possible.
Maintenance request: The analyzer will also indicate when maintenance is needed to ensure that the equipment remains in optimal condition for accurate and reliable operation. Remote diagnosis and maintenance planning can be achieved through communication with service software via RS232.
The LS25 analyzer provides clear error messages for various issues, such as global errors, maintenance requests, detector errors, and input signal overruns. These messages correspond to LCD error codes and are helpful for troubleshooting and maintenance.
Installation and debugging:
Installation tolerances: Detailed diagrams are provided for the installation of transmitter and receiver units, including tolerances for alignment and flange angles. This ensures correct settings and maximizes measurement accuracy.
Ethernet connection: AZ20/112112221112E/STD supports Ethernet connection for integration with other systems, facilitating data collection and analysis. This connection option enhances the versatility of the analyzer in various industrial settings.
Application scenarios
Environmental monitoring: used to monitor the concentration of pollutants in the atmosphere, evaluate air quality, and provide data support for environmental protection.
Industrial process control: In the fields of chemical, petrochemical, power and other industries, monitoring the gas composition in the production process to ensure production safety and product quality.
Emission monitoring: Monitor the concentration of pollutants in flue gas emissions, such as sulfur dioxide, nitrogen oxides, etc., to help enterprises achieve environmental emission standards.
Research experiment: Provide precise gas analysis data for researchers to support scientific research and experimental work.
Connection method
The transmitter unit of AZ20/112112221112E/STD can be connected to the AZ20/112112221112E/STD central unit (outdoor use, acid and UV resistant) through an Ethernet cable. When using the LS25 service interface, the LS25 Ethernet port will be closed. If AZ20/112112221112E/STDis integrated into the customer network, the first Ethernet interface X09 must be used to connect to the customer network, and the second Ethernet interface X08 must be used to connect the analyzer to the central unit of AZ20/112112221112E/STD.
Conclusion:
ABB’s AZ20/112112221112E/STD laser analyzer is a comprehensive gas analysis tool that provides advanced functionality and safety certification for various industrial applications. A powerful and stable gas analyzer, with its high precision, wide measurement range, multiple gas measurements, and automatic calibration characteristics, its remote operation capability, integration capability, and detailed error handling capability make it a valuable tool for continuous monitoring and analysis of gas composition in potential explosive environments.
