Tunable Diode Laser Oxygen Analysers in Critical Applications
Oxygen measurement and control is essential for process optimisation and reliability in many industries, and it is important that O2 concentration be controlled or concentration maintained to ensure process control and safety.
Harsh process conditions and consequent maintenance present challenges in procuring precise and consistent measurements. Oxygen analysers based on Tunable Diode Laser (TDL) Spectroscopy provide highly accurate and reliable performance in many applications where other technologies face application challenges such as safety monitoring, flare systems, and combustion and emission control.
TDL oxygen analysers offer superior accuracy and durability by measuring oxygen in situ, or directly from the gas stream without any sampling or conditioning. TDL analysers work on the principle of laser absorption spectroscopy, with a focused and tunable laser beam used to analyse absorption lines that are characteristic of the particular gas species being measured.
The benefits of TDL analysers include higher resolution, speed and accuracy, resistance against cross interference and corrosion, easier calibration, reduced maintenance and operating lower costs.
Offering innovative probe design, single flange connection, SpectraID technology, predictive diagnostics and a range of unique process adaptions, the GPro 500 series TDL oxygen sensor from METTLER TOLEDO combines the benefits of “fit-and-forget” in-line sensors with the performance of a powerful gas analyser.
