LGA-4500 DLAS Laser Online Gas Analysis System for HCN HCL HF C2H2 CH3L CH4 etc

LGA-4500 DLAS Laser Online Gas Analysis System 

Brief introduction

The Process Gas Laser Analysis System of LGA-4500(Extractive Model), the extractive process gas analysis 

based on the technology of diode absorption spectroscopy (DLAS),is able to make online analysis on carious process gases 

with high dust or high pressure after the extractive treatment and is with such features as strong adaptability and high reliability.

Features

1.Laser extractive measurement, high measurement accuracy, strong anti-interference ability

2. Optical non-contact detection, with the ability to direct measure gas with high temperature and strong corrosion

3. Simple and reliable extractive treatment equipment, with the possibility to be directly installed at the process pipeline

4.While system explosion-proof, supporting the automatic compensation of gas temperature and pressure.

5. Corrosion Resisting High Temperature Type Extractive Pipeline

System Composition

The Process Gas Laser Analysis System of LGA-4000 series Extractive Model) consists of the transmitting unit, the receiver unit, the measurement gas chamber and others. 

The detecting laser, emitted by the transmitting probe, shall pass through the measurement gas chamber, shall be received by the optical sensor of the receiving probe 

and shall be transmitted to the transmitting unit to process and to display after the receiver unit making spectral analysis.
