Model TDLS8000

Tunable Diode Laser Spectrometer

GS 11Y01D01-01EN

n Overview

Yokogawa’s new TDLSTM8000 houses all of the industry’s leading features in one robust device. The platform design is for in situ measurements which negate the need for sample extraction and conditioning.

The non-contacting sensor allows for a variety of process types including corrosive, abrasive and condensing.

The rst generation platform has been proven in many

others for the measurements of O2, CO, CH4, NH3, H2O and many more NIR absorbing gases.

This second generation platform has improved reliability and ease of installation and maintenance while still meeting or exceeding designed application demands.

Note:

When using TDLS8000 as CE marking compliance

product, it has following limitation. General purpose model (-G1, -G2): The upper limit of the measurement gas

ATEX model (-S1, -S2): The upper limit of the measurement gas

An unstable gas in this context is a gas liable to

transform itself spontaneously, producing a sudden

pressure increase. Such transformation as an example can result

from a relatively small variation of an operating

parameter (e.g. pressure, temperature, presence

of catalyzing material) in a conned volume. This includes gases that are classied as

chemically unstable gases according to CLP

Regulation (EC) No 1272/2008 as amended.

Theoretically, instrument air could be used as a purge gas for all of the below applications except for oxygen or H2O measurement. Choosing between using nitrogen or instrument air or purge gas will ultimately depend upon further application details and the desired precision of the measurement.

time basis. The e󰀨ect is specic to each di󰀨erent

b. If the gas temperature is relatively equal to the

ambient temperature, then an integral sensor value may be utilized by the analyzer. This active ambient value is used real time by the analyzer to provide a temperature compensated reading.

c. If the gas temperature is variable, then an

external sensor value may be utilized by the analyzer. This active input value can be used in real time by the analyzer to provide a temperature compensated reading.

B. Pressure: The pressure of the measured gas must

be taken into account by the analyzer so that the reading can be corrected on a real time basis. The

e󰀨ect is specic to each di󰀨erent measurement

gas. a. If the gas pressure is constant at the desired

measurement condition, then a xed gas

pressure may be programmed to the analyzer.

This xed value can be used in real time by the

analyzer to provide a pressure compensated reading.

b. If the gas pressure is variable, then an external

sensor value may be utilized by the analyzer. This active input value can be used in real time by the analyzer to provide a pressure compensated reading.

● YH8000HMIUnit

The YH8000 is an HMI designed specically for the

TDLS8000 series. The YH8000 features an easy-touse touchscreen 7.5 inch color LCD which can be used to display maintenance information, display alarm statuses and records, and set all parameters of the TDLS8000.

The YH8000 can be installed directly on the TDLS8000 series or installed remotely.

An Ethernet connection is used to connect the YH8000 to up to four TDLS8000 series simultaneously via a hub.
