Product Description

Yokogawa Probe type Tunable Diode Laser Spectrometer TDLS8100/TDLS8200 Gas Analyzer



Yokogawa’s new TDLS8100 continues to house all of the industry’s leading features from the TDLS8000, but now only requiring a single-flange installation. An in-situ measurement with a probe still removes the requirement for sample extraction and conditioning and can be used in variety of aggressive process conditions.

The 0.5 meter measurement area of the probe provides some averaging improvement compared with traditional point-sensor technologies, and has flexible positioning of that measurement area with different insertion lengths being offered.

- Measuring with a catalytic sensor on a COe meter poses challenges for durability and data acquisition -

The TDLS8200 is equipped with two systems of lasers that can measure O2 and CO or CH4 in a single unit to overcome such challenges.
You can replace existing sampling devices with either of these.

Built upon Yokogawa’s second generation of TDLS analyzers, the platform still retains its improved reliability, ease of installation, and reduced maintenance requirements, but now does so with lower total-installed cost for O2, CO, CO or CH4, NH3, HCl measurements.


Features and Benefits

Reduced Installation and Maintenance Costs

  • Single-flange installation eliminates the difficulties associated with aligning cross-duct solutions
  • Measure in locations where cross-duct TDLS technology was not feasible due to obstructions or accessibility issues
  • Easy installation with no sample system
  • On-board diagnostics with 50 days of data and spectral storage ensure that minor issues can be identified before they become more serious problems
  • Fully field repairable
  • Compliant with safety level SIL2 for safe operation [TDLS8200 is applying]
  • Explosionproof/flameproof for installation in CID1/Z1 or CID2/Z2 (when conbined with YH8000 Z2) areas [TDLS8200 is applying]
  • No consumables are used which reduces equipment and time-related costs
  • No re-calibration is required
  • HART and Modbus TCP come standard to maximize remote diagnostics and configuration capabilities with a single cable run for each
  • Manual, semi-automatic, or automatic validations can be performed to regularly test analyzer performance while on process

No Light Adjustment

High Speed Accurate Measurement

  • 2 second measurement update with as little as 1 second optional
  • TruePeak technology keeps an accurate measurement, even when the process gas changes composition, temperature, pressure, or dust loading
  • An in-situ probe eliminates sample lag introduced by comparable extractive technologies


Seamless User Interface

  • Intuitive 7.5” touch-screen HMI configurable for 10 different languages
    ( Japanese, English, German, French, Spanish, Portuguese, Russian, Hungarian, Korean and Chinese )
  • Intuitive operability
  • Equipped with trend function, improved display function
  • CID2/Z2 area rating on the HMI allows for local placement of the primary user interface in the majority of installation areas
  • Installation of our free PC-HMI software duplicates the same user interface as the YH8000 HMI for more budget sensitive applications

Touch screen 7.5 inch color LCD on HMI

TDLS8100 Probe type Tunable Diode Laser Spectrometer – flowcell type

For applications where the TDLS8000, TDLS8100 or TDLS8200 could not be installed or inserted due to process size, etc., a sampling system can be constructed by replacing the probe part of the TDLS8100/TDLS8200 with a flow cell part . Please contact Yokogawa.
