Laser Extractive Gas Analyzer

The GLE laser extractive gas analyser is a flameproof, bypass-type tunable laser analyser for industrial on-line analysis and environmental on-line monitoring. It suits harsh conditions such as high temperature, high humidity, high dust and high pressure, and small pipes where an in-situ analyser is not applicable. A jet pump extracts the sample gas, which is filtered to remove dust, heated to avoid condensation and, for hot processes, cooled before it reaches the analysis module. Single-line spectrum technology keeps the measurement free from background gas interference, while automatic calibration, back-flushing and auto purge reduce maintenance.

Features

• Bypass (extractive) installation for conditions unsuitable for in-situ measurement
• Single-line spectrum technology, free from background gas interference
• Automatic calibration and back-blow
• Auto purge function to cut maintenance cost
• Integrated structure with transmitter and receiver on one back board
• Hall-effect buttons for easy operation
• Flameproof Ex d IIC T6 Gb, enclosure IP66
• Analogue inputs for temperature and pressure compensation

How it works

• A jet pump draws the sample gas through the gas path
• The gas is filtered, heated and, at high process temperatures, cooled
• The laser analysis module measures the conditioned gas
• Closing the ball valve allows a calibration; opening the back-flush valve keeps the gas path clear
• Configuration varies by duty: for high pressure a relief valve is added and the air pump removed; for high temperature the heat tracing runs hotter

Applications

• Industrial on-line process gas analysis
• Environmental on-line emission monitoring
• High-dust, high-humidity or high-temperature gas streams
• Small pipes unsuitable for in-situ analysers
• Hazardous areas requiring flameproof equipment
