LGA-4000 Process LaserGas Analysis System

Product catalog summary

Overview: The LGA-4000 Process Laser Gas Analysis System by Teledyne utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology. It is designed for in-situ gas detection across various challenging environments, offering high accuracy, quick response, and low operational costs. The system is applicable in industries such as metallurgy, petrochemical, and environmental protection.

System Components:

Transmitter Unit: Comprises a diode laser, laser driver, and HMI modules for laser driving and spectrum data processing.
Receiver Unit: Includes a photoelectric sensor and signal processing modules for converting light intensity into electric signals.

Configuration: The LGA-4000 features a two-sided sequenced system for trace moisture analysis in chlorine, equipped with PLC and touch-screen HMI. It supports both in-situ and extractive measurements, depending on the application.

Features:

High sensitivity and unique optical design.
Explosion-proof, compact, and reliable structure.
Modular design for easy maintenance.
Digital interface for simple operation.

Specifications:

Linearity: 2% of FS, application dependent.
Response time: Less than 1 second.
Enclosure protection: IP65.
Power supply: 24VDC, with optional 220VAC.

Gas Measurement Capabilities: The system can measure various gases such as O2, CO, CO2, H2O, H2S, HF, HCL, HCN, NH3, CH4, C2H2, and C2H4, with specific lower detection limits and measurement ranges.

Technology Comparison: Compared to conventional online analysis systems, the LGA-4000 offers real-time, continuous measurement without the need for sample gas evacuation, faster response times, higher reliability, and lower operational costs.

Technical Principle: The system uses a laser spectral scanning technique with modulation to accurately calculate gas transmittance, automatically compensating for environmental parameter changes such as temperature and pressure.

Installation and Maintenance: The system requires minimal maintenance (less than twice a year) and calibration, with a straightforward installation process involving various modules and interfaces.
