2.1 Functional Description

TunableDiodeLaser(orTDL)measurementsarebasedonabsorptionspectroscopy.TheTDLS220AnalyzerisaTDLsystemandoperatesbymeasuringtheamountoflaserlightthatisabsorbed(lost)asit travels through the gas being measured. In the simplest form a TDL analyzer consists of a laser that produces infrared light, optical lenses to focus the laser light through the gas to be measured onto a mirror and back through the gas and then on to a detector, the detector, and electronics that control the laser and translate the detector signal into a signal representing the gas concentration.

Gasmoleculesabsorblightatspecificcolors,calledabsorptionlines.ThisabsorptionfollowsBeer’s Law.

UsingaTunableDiodeLaserasalightsourceforspectroscopyhasthefollowingbenefits: •Sensitivity.Aslowas10-6

by volume, lower with pathlength enhancement. •Selectivity. The narrow line width of the laser is able to resolve single absorption lines. This provides more choices of a particular peak to use for measurement, usually allowing one isolated peak to be used. •Power.Diodelasershavepowerrangingfrom0.5mWto20mW. •Monochromatic,nodispersiveelement(filter,etc.)required.Lightsourceitselfisselective. •Tunable.Wavelengthcanbesweptacrosstheentireabsorptionfeature,whichallows resonant(peak)andnonresonant(baseline)measurementduringeveryscan.

Theanalyzerisdesignedforoperationoutsidebuildings,atnormalenvironmentalconditions(seeEnvironmentalspecifications,page11).However,itmustbeprotectedfromdirectrainandsnowfall.Mounting in a vibration free environment will ensure prolonged service life. Mounting in vibration prone areasmayintroduceoperationalissues.Pleaseconsidermountinglocationwithcare.

The actual measurement is NOT affected by vibration, it is an instrument life-time reliability consideration.

5.2 Sample Inlet and Outlet Considerations

The following criteria should be considered when selecting the installation point in respect to the process conditions(1/4”ODSwageloktubefittings):

Process Gas Condition: - The sample should be clean, dry, non-condensing at the inlet to the sample cell. The dew point of the sample should be below the sample cell operating temperature. If the sample cell is not heated and un-insulated then the sample must be non-condensing through the entire ambient operating conditions.

NOTE: Oils, waxes, impure cleaners, and other deposits on the sample cell/mirror will cause optical noise and subsequent analytical performance degradation. Please take all necessary precautions to ensure the incoming sample gas is clean and dry at all times!

ProcessGasFlowConditions–Typically1-10lts/minsampleflow.Aso-callednormalflow-rate wouldbeintheorderof2-3lts/min.Higherflow-rateswillimprovethesamplelagtimewithinthe measurementcell.Sampleflowmetercanbetypicallyinstalledontheinletwhenequippedwith needlevalve.Excessiveflow-ratesmayresultingastemperaturecontrolissuesifthedeltaTof incominggasandcelltemperatureset-pointexceed15degC. ProcessGasTemperature–Itisrecommendedthatthesamplegasinletremainswithin+/-15deg C of the sample cell temperature set-point. If the sample cell is un-heated then the sample gas shouldbewith+/-10degCoftheambienttemperature.Pleaseensurethattheprocessgas entering the sample cell is above the dew point. If necessary, utilize membrane or coalescing type filterdeviceontheinlet. Lower gas temperatures generally lead to better measurements.

•ProcessGasPressure–Itisrecommendedthattheanalyzerbeinstalledatalocationwhere pressurefluctuationsareminimized.Generallyasaguide,ifthetemperatureofthegasatthepoint wheretheanalyzeristobeinstalledistovarybymorethan+/-0.05Bar(+/-0.725psi)thenan “Active” input signal should be used for compensation. Ensuretheanalyzerhasbeenselectedandconfiguredtosuitthemaximumoperatinggas pressure. Ensuretheprocessisolationwindowshavebeenselectedandconfiguredtosuitethemaximum design gas pressure. Lower gas pressures generally lead to better measurements.

Process Dust/Particulate Matter–Itisrecommendedthattheprocessgasisfilteredto<2uusingpro-cessanalyticalgradefiltrationsystems.



5.3 Wiring Details Connect protective ground to the designated terminal of the analyzer. Use minimum 14 AWG or equivalent. The analyzer mains must be connected to an end user provided disconnect device (a switch or circuit breaker) with 250V, 10 A ratings. The disconnect device must be located within 3 meters of the equipment, and not obstructed or placed out of reach in some way. It must be clearly labeled as the disconnect device for the TDLS220 equipment. The disconnect device must be easily accessed and operated by the authorized personel. Water tight conduit/ cable connections must be used for the customer connections. The customer connections should terminate in a normal environment (i.e. indoors).

6.3 Non-Process Parameters (required when Instrument Air Purging)

In order for the analyzer to measure correctly under these purge conditions, the analyzer must know the correct parameters such that the measured output value has been compensated i.e. the oxygen in the purge gas has been taken into account when determining the process oxygen concentration.

Calibration – The analyzer MUST be calibrated (Zero and Span) as per the normal methods outlined in the standard User’s Guide. When performing a Zero Calibration, ensure that the entire optical path is purged with Nitrogen. When performing a Span Calibration, ensure the correct procedures are followed!

ADVANCED CONFIGURE MENU (UPDATED)TheAdvancedConfigureMenuhasbeenupdatedwitha sub-section titled Non-Process Parameters.

NON-PROCESS PARAMETERSThese non-process parameters are for the measured gas in the optical path but outside of the process path length.

TheseparametersMUSTbeenteredforanaccuratemeasurementifthepurgeisnotnitrogen(whenmeasuringOxygen).



NON-PROCESS PATH LENGTHThisistheopticalpathlengthinsidethelaser&detectmeasurementunit.Typicalvalueswouldbe3.5”to4”withthedefaultvaluetouseat3.75”.Notethatthisdimensionwillvarybetween analyzers.

Contact Yokogawa if unsure.

NON-PROCESS PRESSUREThis is the pressure of the non-process gas. Typically, thiswillbeclosetoatmosphericpressureof1.01BarAor14.7PsiA.Checktheactualoperatingconditionsandentertheappropriate value. Contact Yokogawa if unsure.

NON-PROCESS TEMPERATUREThis is the temperature of the non-process gas with two modes of input:

ACTIVEAMBIENT-ambientgastemperaturederivedfromintegral sensor on detector circuit with offset adjustment (typically-18degC).Notethisoff-setisduetotheinternalheat of the controller unit, where the detect board is located in TDLS220

FIXED–manualinputoffixedtemperaturevalue

NON-PROCESS CONCENTRATIONThis is the concentration of the non-process measurement gas.ForInstrumentAirpurgegas,thetypicalvaluewouldbe20.9%O2.

IfmeasuringCOintheprocessgasandthepurgegasisInstrument Air, then these parameters are not applicable becausetheCOconcentrationstypicallyfoundinInstrumentAir are below practical detection limits.

The most common issues are divided into two categories: • Warnings. These are conditions which will affect the analyzer reading but not cause complete lossofmeasurementintegrity.Anexamplewouldbereductionoftransmission(amountoflaser poweratthedetector)whichcouldindicatewindowfouling,wherethemeasurementisstill being made, but further loss of transmission will cause loss of measurement.• Faults. These are conditions where the measurement is lost, or degraded past the point of reliability. An example would be loss of transmission, which could indicate complete miss- alignment or laser failure.

9.1 Configuring Data Capture:



To select the Spectrum capture, stay in Advanced Menu user mode and the Data sub section – select Spectrum Capture

To store spectrum automatically, select Auto. If you do not wish tostoreanyspectrumfileduringnormalanalyzeroperation,thenselect Manual mode.

Determine the rate at which you would like the analyzer to capture spectrumfilesandunderwhatcondition.Thedefaultconditionisrelated to the number of measurement however, the user can select RelativeorAbsolutechangespendingthesitespecificconditions/requirements.

The more frequently spectrum are stored then the larger the MMDDYY.spefileswillbecome.

NOTE: Capturing every spectrum for one day can create a single day file in excess of 30MB. This will reduce the number of daily results that are stored in the analyzer – Choose the parameters carefully!
