I.Introduction

A.GeneralDescription

TheMS2600Eisahigh‐resolutionmeterdesignedtotransmitcorrosion(metalloss)datafroman
ElectricalResistance(ER)probetoaplantcontrolsystemorotherrecordingdevice.TheMS2600E
utilizestraditional4‐20mAcurrentloopcommunicationandisloop‐powered,soitrequiresonlyatwo‐
wireinterface.Thisresultsinasimpleandlow‐costinstallation.Theuseofthe4‐20mAprotocolalso
allowstheMS2600Etobeplacedgreatdistancesfromthecontrolsystemorrecorderwhile
maintaininggoodnoiserejection.Practicalcurrentloopdistancescanbemanythousandsoffeet(see
pages6and7forexactspecifications.)
TheMS2600EiscompatiblewithalltypesofMetalSamplesERprobes,aswellasanystandardER
probefromothermanufacturers.Unlikecompetitors’products,theMS2600ETransmitterdoesnot
requirefactorymodificationtoaccommodatedifferentprobetypes.Theprobetypecanbeeasily
changedatanytimeusingtheon‐boardprobeselectionswitches(seepage9.)
TheMS2600Eisavailableasdirect‐mount(standard)orremote‐mount.Inthedirect‐mountversion
theMS2600EismounteddirectlytotheERprobe.Thisoptionoffersthesimplestinstallationand
minimizesnoiseproblems.Theremote‐mountoptionallowstheMS2600Etobemounted
independentlyfrom(butincloseproximityto)theERprobe.Itisthenconnectedtotheprobeviaa
shortprobecable.(Seepage5formountingdiagramsandspecifications.)
B.PrinciplesofOperation

TheMS2600EoperatesontheElectricalResistance(ER)techniqueandisusedinconjunctionwithan
ERprobe.TheERprobeutilizesaresistivesensingelementmanufacturedfromthematerialof
interest(oracloseapproximation)whichisexposedtoacorrodingenvironment.Thisiscalledthe
ExposedorCorrodingElement.TheresistanceoftheExposedElementisdirectlyrelatedtoits
thickness,soastheelementcorrodestheresultinglossofmetalcausesaproportionalincreaseinthe
element’sresistance.TheprobealsocontainsaninternalReferenceElementwhichisusedto
compensatefortheinfluencesoftemperatureontheExposedElement.
TheMS2600EisdesignedtoworkwithanystandardERprobe,butitisrecommendedthatCylindrical
andLargeFlushtypeprobesbeusedtoensureoptimumperformance.Theirphysicaldesignplaces
theReferenceElementincloserproximitytotheExposedElementcomparedtootherprobetypes,
providingmoreeffectivetemperaturecompensationandthusreducingtheeffectsofthermalnoise.
Becausetheyaredesignedtocorrode,ERprobesaresacrificialinnature.EachERprobewillhavea
finitelifethatisbasedontheelementthickness.ERprobesareavailableinanumberofgeometries
andthicknessesdesignedtosuitawidevarietyofapplications.Table1liststhecommonERelement
optionsavailablefromMetalSamplesandtheeffectivelifeofeach.

TheMS2600EmeasuresanERprobeutilizingahigh‐resolution,16‐bitmeasurement.Thisallowsthe
MS2600Etodetectmuchsmalleramountsofmetalloss,thusrespondingfastertocorrosionevents
andupsets(comparedtotraditionalERmeters.)At16‐bitresolutiontheMS2600Ecanmeasure
metallossamountsassmallas0.0015%oftheprobelife.

MetallossreadingstakenbytheMS2600Eareconvertedtoalinearized4‐20mAcurrentloop
output.The4‐20mAsignalcanbefedintoaplantcontrolsystemorotherdevicesandscaled
accordinglytoreflectmetalloss.Thencorrosionratescanbecalculatedbasedonthemetalloss
dataovertime.Thisiscoveredinmoredetailonpages11and12.MoreinformationonERprobes,


Ui=28V,Ii=93mAandPi=0.65W


Wheneveranelectricallydrivensensorormeasuringdeviceisusedinapotentiallyexplosive
environmentthemeasuringsystemmustbeinstalledinsuchawaythatelectricalenergyiseither
effectivelyisolatedfromtheexplosiveenvironment(viaexplosive‐proofcontainers,cableconduits,
etc.)ortheamountofelectricalenergyproducedinthehazardousareamustbelimitedtoan
intrinsicallysafelevel.

LimitingelectricalenergyisthemostpracticalmethodofprotectingtheMS2600Emeasuringsystem
whentheTransmitterisinstalledinahazardousarea.IntheMS2600Esystem,electricalenergylimits
aremaintainedbytheuseofarepeatersafetybarrier(oritsequivalent)installedinthe4‐20mA
currentloopperstandardpractice.Thesafetybarriermustbelocatedinthesafeareanearthe


boundarybetweenthesafeandhazardousareas.Thesafetybarrierwillrepeatthesignalcurrent
generatedbytheTransmitterandwillrelaythesignaltothedatareceivingstation.

Caution:WhenasafetybarrierisusedwiththeMS2600Esystem,thecurrentloopcablemustbe
connectedtothebarrier’shazardousareaterminals.Allotherconnectionsmustbemadetothe
barrier’ssafeareaterminals.

ThetypeofrepeatersafetybarrieremployedintheMS2600Esystemdependsonthespecific
classificationofthehazardousenvironmentinquestion.MetalSampleswillprovide,uponrequest,
assistanceandtechnicaladviceintheselectionofarepeatersafetybarrieroritsequivalent.

b.TestingtheCurrentLoop

i.Calibration

TheMS2600Eisfullycalibratedwhenshippedfromthefactory.Thecalibrationsettingsarefixedto
avoidaccidentalchangewhichcouldresultinerroneousdata.Nofieldcalibrationisrequired.
However,itisimportanttotesttheMS2600Euponinstallation,andduringperiodicmaintenance
inspections,toensuretheunitisoperatingproperly.

ii.Testingloopoutputzero(4mA)andspan(20mA)

TheMS2600EProbeSelectionSwitches(page9)offerthreetestsettingsthatallowtheunittobe
placedintovariousdiagnosticmodesasfollows:

1) 4mAOutput–Forcesaconstant4mAoutputonthecurrentloop.
2) 20mAOutput–Forcesaconstant20mAoutputonthecurrentloop.
3) 4‐20mASweep–Causestheoutputtocontinuallycyclefrom4mAupto20mA.

Thesetestmodescanbeusefulwhentroubleshootingproblemswiththecurrentloopwiringand
DCS/SCADAsystem.

iii.TestingtheMS2600EwiththeMeterProver

AMeterProverisprovidedtoallowroutinechecksoftheMS2600E.TheMeterProversimulatesa
WireLooptypeprobeatafixedvalue.TotesttheMS2600EwiththeMeterProver:

1) Disconnectpower.
2) DisconnecttheMS2600Efromtheprobe(oriftheMS2600Eisremote‐mounted,disconnect
theprobeextensioncablefromtheprobe.)
3) ConnecttheMeterProvertotheMS2600Eprobeconnectorstem(ortotheprobeextension
cableiftheMS2600Eisremote‐mounted.)
4) LoosentheMS2600EEnclosureLockScrew.
5) UnthreadandremovetheMS2600Ecover.
6) ChangetheProbeSelectionSwitchestotheWireLoopposition(seepage9.)
7) Reconnectpowerandallowtheinstrumenttomeasureforseveralminutestostabilize.
8) Afterseveralminutesobservethetransmitteroutput.Theoutputshouldcloselymatchthe
valueprintedontheMeterProverlabel.

IfthetransmitteroutputmatchestheMeterProvervalue,youmayreturntheProbeSelection
SwitchestotheirprevioussettingandreconnecttheMS2600Etotheprobe.Ifthetransmitteroutput
showsasignificantdifferencecomparedtotheMeterProvervalue,furthertroubleshootingmaybe
required.Refertopage14fortroubleshootingorcontactthefactoryforfurtherassistance.

BesuretoreinstalltheenclosurecoverandtightentheLockScrewwhenputtingtheMS2600Eback
intoservice.

c.InterpretingData

i.MetalLoss
TheMS2600EmeasurestheMetalLossofanERprobeandconvertsthatvaluetoalinearized4‐20mA
currentloopoutput.The4‐20mAoutputisdirectlyproportionaltothecumulativeMetalLossofthe
ERprobeatanygiventime.Theoverallspanofthe4‐20mAoutputisproportionaltothelifeofthe
probeinuse,soforDCS/SCADAprogrammingthe4‐20mAsignalcanbescaledasfollows:

4mA=0mils(0%MetalLoss)
20mA=ProbeLifeinmils(100%MetalLoss)

TheProbeLifecanbefoundinTable1andisalsolistedontheMetalSamplesprobetag(asthe
“Multiplier”.)



Figure6.MetalSamplesProbeTag
Figure7illustratestherelationshipbetweenLoopCurrentandMetalLoss.Inthisexampleaprobe
witha10‐millifeisassumed.However,theXaxiscouldbechangedtorepresentanyProbeLife.
Figure7.OutputRelationship
Asseenhere,thetransmitteroutputbeginsat4mAforanewprobe(zeroMetalLoss)andincreasesas
theprobeelementcorrodes,eventuallyreachingamaximumof20mAwhentheprobesensing
elementhasbeencompletelyconsumedbycorrosion(inthiscase,10milsofMetalLoss.)Atthistime
theprobehasreacheditsend‐of‐lifeandmustbereplaced.

ii.CalculatingCorrosionRate


Asexplainedpreviously,ERprobesandinstrumentsreportMetalLoss.However,thevaluethatisof

12

ultimateinterestisCorrosionRate.TheCorrosionRateisessentiallyMetalLossovertime,sothe
CorrosionRatecanbecalculatedusingthefollowingformula:
CorrosionRate󰇛mpy󰇜  ∆LoopCurrent󰇛mA󰇜
16 365 ∆Time󰇛days󰇜 ProbeLife󰇛mils󰇜

where:
  LoopCurrent(mA)isthedifferencebetweentworeadings

 Time(days)isthetimedifferencebetweenthosetworeadings

Itisacommonpracticetoprogramthisformulaintothecontrol(DCS/SCADA)systemandhaveit
calculateCorrosionRateonacontinualbasisfromtheMetalLossdata.Thechallengeindoingthisis
selectinganappropriatetimeinterval.Usinganintervalthatistooshortmaygiveerraticresults,
whileselectinganintervalthatistoolongmaygiveresultsthatareinsensitivetosystemupsets.The
idealtimeperioddependsonmanyfactors,andwillvaryfromsystemtosystem.Itmaytakesome
trialanderrortosettleonthebesttimeperiodforyourinstallation.

InsomecasesitmaybenecessarytoreviewtherawMetalLossdataandmanuallyapplythe
CorrosionRateformulatoperiodsofinterest.Forexample,lookatthegraphbelowandseehow
muchthecalculatedCorrosionRatecanvarydependingonthetimeperiodused.

Figure8.CorrosionRatescalculatedfromMetalLossdata
Whileeachoftheresultsisvalidfortheselectedtimeperiod,theoneofmostinterestisthevalueof
11.81mpywhichrepresentssometypeofsystemupset.WhentheCorrosionRateiscalculated
automaticallyonapre‐selectedtimeperiod,thereisnoguaranteethattheselectedtimeperiodwill
alwayscoincidewithsystemupsetssuchasthis.Thatiswhymanualreviewandinterpretationof
MetalLossdataisalsohelpful.


d.Commissioning

OncetheMS2600Ehasbeeninstalled,tested,andproperlyconfiguredfortheprobeinuse,itcanthenbe


D.Troubleshooting

IftheMS2600Edoesnotseemtoperformasexpected,checkthefollowingitems:


CAUTION:BeforeperforminganytestsormaintenanceontheMS2600E,ensurethatallhazardousarea
requirementsaremet.


1. Ensurethattheprobeisoperationalandisnotcompletelycorroded.Thiscanbedoneintwoways.
a. TesttheprobewithaportableERmeterifavailable.
b. Testtheprobewithaportableresistanceorcontinuitymeterasfollows:
i. Connectonetestleadtopin‘A’oftheprobes6‐pinconnector.
ii. Measurecontinuitytoeachoftheotherpins.Thereshouldbecontinuity(low
resistance)toeachpin.
NOTE:Continuityoneachpindoesnotensurethattheprobeisgood.However,ifyou
findanopencircuitonanypinsthenitisalmostcertainthattheprobeisbadandshould
bereplaced.
2. EnsurethattheProbeSelectionSwitchesaresetcorrectlyfortheprobebeingused.Confirmthe
probetype,andrefertoTable2onpage9toverifytheappropriateswitchsettings.
3. Performavisualinspectionofthecircuitboardstolookforanysignsofmechanicalorelectrical
damage.
4. Ensurethatallelectricalcablesandwiringareingoodcondition.
5. Ensurethatallelectricalcontactsaresecureandfreeofcorrosion.
6. Ensurethatthereisadequatesupplyvoltageatthe4‐20mACurrentLoopConnector.
7. Verifythatthesupplyvoltagepolarityiscorrect.
8. Ifthereisinsufficientsupplyvoltageonthe4‐20mACurrentLoopConnector,checkthesafety
barrier(ifapplicable)forablownfuseoranyotherfailure.
9. TesttheMS2600EusingthesuppliedMeterProver(seepage10.)
10. TesttheMS2600Ewithalocalmulti‐meterorloopcalibrator.

Thesebasicchecksshouldindicatethesourceofanyproblem(probe,powersupply,wiring,etc…)Ifitis
determinedthattheMS2600Eismalfunctioning,orifyouneedfurtherassistanceintroubleshooting,
contactMetalSamplesTechnicalSupport.
