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.
