I. Introduction
A. InstrumentFunctionOverview
TheMS3500E/3510EDataLoggerisdesignedto provide a continuous record ofcorrosiveactivityin
remotelocationsthatareinfrequentlyvisited, such ascross-countrypipelines,andunmannedproduction
platforms.However,thisunitfindsequalapplicationinlocationsthatareinconvenientordifficultto
accessona regular basis, suchasrefineryoverheads,andflue-gasstacks.
TheMS3500E/3510Eiscompletelyself-containedwiththeonboardbatterysystemsupplyingthetotal
powerrequirementfor operation. It canbeusedwithanyof Metal Samples’ ERprobes,orthoseofall
othermajormanufacturers.Onceinplace,itwillautomaticallyreadtheprobeatcustomer-selected
intervalsandstoretheresultingdataintheunit’sonboardmemory.Theonboardmemorywillcollectup
to3,100datapointsbeforedata download is required. The datacollectionintervalisprogrammablein
hourlyincrements.Evenattheminimumdatacollectioninterval(1hour),datadownloadingneedonlybe
performedeveryninetydays.Withmore practical data collection intervals (8 - 12 hours), the unit may
beunattendedfor as longas6-8months between downloading operations.
Anoptical,infrared,RS232communicationlink is provided for datadownloadtoeitheraPCorMetal
Samples'MS1500E portable ERdatalogger.Downloadeddata may beanalyzed,reviewed,or re-
portedbyconventionalspreadsheet,database, or mathematical software packages.
Theinfraredcommunicationlink isanintegralpartoftheintrinsicallysafedesignoftheMS3500E/
3510E.Opticalinsteadofelectrical,thisuniquefeaturepermitsdatadownloadingwithoutremovingthe
instrumentor“memorymodule” fromthehazardousarea.
AnotheruniquefeatureoftheMS3500E/3510Eis the highlevelofonboardintelligence.Thetwo-line,
20-characterLCDallowsvisualreviewofallhistoricaldatainmemoryandreads directly as “total metal
loss”and/or“averagecorrosionrate”. Thisisincontrasttoothercommerciallyavailableunits that store

TheLCDscreen,togetherwiththe2-keymembranekeypad,provides a user-friendly,interactive,
promptingsystemthatis used for bothsystemsetupanddatareview.ThismakestheMS3500Ethe
mostadvancedunitofits type on the market.
Byaddinga4-20mAcommunication facility, the MS3500E becomes an MS3510E.Thisallows
continuoustransmissionofdata, via a 4-20mAloop,to a plant computer orcentraldatalogger, for
integrationwithotherreal-timeprocessparameters.This data transmissioncanbeaccomplishedwithout
disruptionoftheunit’s basic logginganddatastorageoperations.The 4-20mAloopextends the capa-
bilitiesoftheunittoincludeconventional,in-plant,real-timedatacommunication.

B.BatteryInstallation
TheMS3500E/3510Einstrument uses six 1.5V,AAsize batteries,connectedinseries,asaprimary
powersource. While anyAAsize battery canbeused,Duracell or ProcellTypeMN1500 or PC1500

adaptorinthecase of a retrievable probeusedinatwo-inch,high-pressure,accessfitting(see Figure
12,p.41).However,inmanyinstancesitiseitherinconvenientorundesirable to mount theinstrument
directlyontothe probe. Forthesecircumstancesa546810,ten-foot, extension cable isprovided.The
extensioncablehasintegralconnectors withaguidingkeywaytoensurecorrectpinalignment when
attached.Thefemaleconnector (MS3106E145-6S) mateswiththe probe, orHA700110-5probe
adaptor,andthe male connector mateswiththecentralterminalonthebase of the MS3500E/3510E
unit.
The length of the extension cable has been carefully determined so as to avoid excessive
signalnoise. Longerextension cablesshouldonly beemployed afterconsultationwith Metal
Samples.
