TDLS220 Process Oxygen Analysis The Tunable Diode Laser Spectroscopy (TDLS) Analyzer, TDLS220 is specifically designed for accurate, reliable and low maintenance measurement of volume percent (vol%) oxygen in process gas streams. Typical applications include: • Vent headers and flare lines • Vapor Recovery Systems • Reactor Control Bulletin 11Y01B02-01E-A

The first tunable diode laser analyzer, designed specifically for process analysis Innovative
Dependable
Accurate
Process Hardened
Our TruePeak Process Laser Analyzer uses a tunable diode laser and measures across an infrared absorbance region. This means you can make measurements in the most demanding applications.
The TruePeak measurement integrates the area of the absorbance rather than measuring peak height or peak width value alone. This means you get a true interference free analysis.
TruePeak measurement ensures accuracy even during simultaneous sample pressure, temperature, and background gas changes.
Flexible installation options, materials of construction, and validation methods make the Yokogawa TDLS a perfect solution for the most aggressive process applications.
User Interface 4Stand Alone • Mini Display (integral or remote), 4x20 VFD with
•
scrolling information 7” Color Screen with Keypad
4Remote Interface Unit (RIU) • Interface only, not required for analyzer operation • 7” Color Screen with Keypad • Connects 1 to 4 analyzers with central display/keypad
Reliability 4Enhanced Diagnostics
Built In diagnostics with on board CPU, data storage, and retrieval. No PC required to record data, spectra, and critical diagnostics. • Data transfer via wired/wireless Ethernet, memory stick or PDA • Spectra capture (timed, manual capture, event-based)
4Maintenance • All components field replaceable • Remote diagnostics and analyzer control

4Wireless - Optional Wireless • WiFi 802.11 4Fully Network Ready
Process Oxygen Analysis Designed as an extractive analyzer to replace traditional extractive analyzer technologies. • Line Power Input (VAC) • Integral Heat Trace Controller • Heat Traced and Insulated Flow Cell • Flow Cell construction 316L or (optional) monel alloy 400 and Kalrez 4079 0-rings
Refinery Oxygen measurement is critical in many refining applications to ensure safety, increase efficiency, and enhance process control. The TDLS220 was designed to provide a near real time measurement that is unaffected by background interferences. Application include but not limited to marine vapor recovery, flare headers, flare gas recovery drums and waste gas from a gas plant.
