Yokogawa Adds TDLS8100 Probe Type Tunable Diode Laser Spectrometer to Its OpreX Analyzer Lineup

23 January 2019

Yokogawa Electric Corporation announces that it has developed the TDLS8100 probe type tunable diode laser spectrometer and will release it for sale on January 23 as part of its OpreX™ Analyzer family. The TDLS8100 is targeted at applications in the oil, petrochemical, power, iron and steel, and other industries that require the ability to directly measure oxygen or carbon monoxide gas concentration at high speeds. With its integrated light launcher and detector, this new probe type tunable diode laser spectrometer significantly reduces the need for the installation of flanges*1 and scaffolding, and thus enables a 50% or greater reduction in installation costs.

The TDLS8100 joins a lineup that includes the TDLS8000 tunable diode laser spectrometer for high-temperature and high-pressure gas concentration measurement applications, and is intended for use in the measurement of flowing gases where there is a need to reduce installation costs. With the addition of the TDLS8100, Yokogawa will be able to provide its customers a greater range of choices on solutions that can help them ensure safe operations and maximize energy efficiency. Within the first half of this year, Yokogawa plans also to release a TDLS8100 model for the measurement of ammonia and hydrogen chloride gas concentrations.

Development Background

Gas analyzers are used in plants to obtain data on oxygen and carbon monoxide gas concentrations that are needed to optimize the air-fuel ratio, thereby reducing energy consumption and helping to ensure safety and compliance with environmental regulations.

Various types of gas analyzers are in use today, including zirconia, infrared, paramagnetic, and laser gas analyzers. Laser gas analyzers can directly measure at high speeds the concentrations of gases such as oxygen, carbon monoxide, carbon dioxide, and ammonia that are absorbed in the near-infrared region. Such instruments do not require sampling systems and achieve superior repeatability*2 and linearity*3. However, such analyzers are costly to install due to the requirement to mount flanges for the light launcher and detector on both side of the ducts, and the need to install scaffolding to access both locations. With the development of the TDLS8100, Yokogawa has enabled a 50% or greater reduction in these installation costs.
