SMALL FOOTPRINT
BIG STEP FORWARD
LASER 3 PLUS TDL MONITOR
Servomex ’ s newest compact analyzer is making a big impact on combustion applications .
The SERVOTOUGH Laser 3 Plus range is comprised of the world ’ s smallest cross-stack Tunable Diode Laser ( TDL ) gas analyzers , each optimized for key application measurements .
Targeted at gas analysis in both the hydrocarbon processing and power generation market sectors , and emissions control , the new family of analyzers includes versions for ammonia slip monitoring for combustion optimization and process control .
The benefits of the Laser 3 Plus analyzers are immediate . Instead of the time-intensive installation associated with traditional , bulky TDL analyzers , they can be installed quickly by just one person due to the compact design and advanced optical improvement that includes a wider acceptance angle of the transmitted light source .
A separate laptop for installation is no longer required , as the Laser 3 Plus now has a new built-in display for configuration and diagnostics .
To ensure precision alignment from the outset , a new mounting assembly for multi-direction adjustment is included and when combined with the new , quick-release mechanism of the heads , fast and accurate reinstallation - without the need for re-alignment - is achieved every time . The new Laser 3 Plus analyzer purge design reduces nitrogen ( N 2
) and air purge costs by an impressive ninety per cent per annum ; a significant return on investment when calculating lifetime operational costs .
The Laser 3 Plus family of analyzers delivers exceptional TDL performance , with a fast response to measuring gas in a wide range of applications . Utilizing the unique Servomex signal processing techniques based upon Wavelength Modulated Spectroscopy ( WMS ), the Laser 3 Plus provides the most stable , repeatable results with minimal cross-interference from other gases present in the matrix .
The Laser 3 Plus analyzers join the SERVOTOUGH Laser range of TDL analyzers , providing the same industryleading performance delivered by Servomex ’ s in-situ cross stack and extractive monitors .
UNIQUE LINE LOCK CUVETTE SYSTEM TRANSFORMS PROCESS SAFETY
To avoid the possibility of ‘ drift ’, that is , the analyzer losing its lock on the gas it is monitoring , the Laser 3 Plus family employs a unique ‘ line lock ’ reference cuvette system . Usually in TDL analysis , a bump cell or reference gas is used , giving a reference directly in the measurement path . However , if the detection is continuous , this can add a measurement error .
If , on the other hand , the detection is interrupted , it is impossible to know if the analyzer has a lock between bumps .
By using a cuvette filled with the gas of interest , the analyzer has a reference that is always available and continuously scanned , providing a much better reading stability . In addition to keeping the analyzer firmly locked on line , the cuvette system requires no maintenance , and has self-diagnostics inbuilt .
