AbouttheRunoutKit
TheCMCP810SeriesElectricalRunoutKitusesindustrystandardsensorstodetectandlocateareasofhighelectrical
runout.ElectricalrunoutmustbeminimizedtoallowProximityprobestoworkproperlywhilethemachineisinoperation.
Thekitcombinesthetypicalindustrialsensorsnormallyusedforpermanentvibrationdetectioninordertoallowforin
shopdetectionofelectricalrunoutusingthesuppliedoscilloscope.Electricalrunoutcanbedetectedandrecordedusing

Inordertodisplayapositiveandnegativegoingsignalinelectronicsanoffsetvoltagemustbeprovidedtoallowthevoltage
signaltoswingupanddown.TodothistheeddyprobedrivercreatesaDCoffsetvoltagefortheACvoltagesignaltoride
on.TheDCvoltageisreferredtoasthe“gap”voltageandistypicallysetto‐12VDC.Sincemostmodernoscilloscopesonly
allowforuptoa5VDCoffsetabuckingcircuitmustbeusedtomovethe‐12VDCoffsettowithintheoscilloscopes

AbouttheSensorInterfaceModule(CMCP810‐SIM)
TheCMCP810SIMSensorInterfaceModuleprovidesasingleaccesspointforthesensorsandoscilloscope,eliminatingthe
needofdualpowersuppliesandamixofwiringinbetween.Aninternallithium‐ionbatteryprovides‐24VDCforthe
ProximityProbeand+15VDCforthePhasesensor.Thebatterycanberechargedusingthechargerprovidedwiththe
CMCP810SIMmodule.Sparebatteriesmayalsobepurchased.ThemainpurposeoftheSensorInterfaceModuleisthe
buckingamplifiercapabilities.TheCMCP810SIMcanremovetheentireDCoffsetsothatonlytheACsignalisviewableon
theoscilloscope.

Thismodelsensorprovidesa200mVoutputpermil
(0.001”)ofelectricalrunoutona4140seriesshaft.An
ProximityProbeismadeupofthreespecificallytuned
components,theprobe,extensioncableanddriver,all
threemustbeconnectedtogetherinorderforitto

AbouttheOpticalSensor
OpticalSensor:

TheopticalsensorprovidedwiththeCMCP810RunoutKitprovidesaphase(location)reference
totheelectricalrunout.ThesensorispoweredbytheCMCP810‐SIMSensorInterfaceModule.
Whenthesensordetectsareflectivesurface,theoutputwillspiketo5VDC.Arollofreflective
tapeisprovidedwiththekit.ThepowerunitfortheopticalsensorcanoperateonACpoweror
ontheinternalbatteries.Theoscilloscopeshouldbesetupsothatatleastonerevolutionofthe
shaftisdisplayedontheoscilloscopescreenwhiletheshaftisturning.Thiswillallowthe
operatortoseetheareaofthehighelectricalrunout.

SensorMountingOptions:
TheCMCP810Kitcomeswith2sensormountingoptions,theadjustablemagneticarmholders
andcustomvicegrips.Theholderscanbeusedwitheithersensorandinanyorientationthat
allowsthesensorssositsecurelyabovethetargetpositions.Itisimportantthattheproximity

ProximityProbe(Runout):
TheProximityProbeshouldbeinstalledinoneofthesuppliedholdersandpositionedabovetheburnishedareaoftheshaft
asspecifiedintheshopdrawings.Theproberequiresagapbetweentheshaftandtheprobetipinorderforittooperate
correctly.ThegapcanbesetbymeasuringtheDCvoltageoutputfromthedriver,positionthesensoruntiltheoutputfrom
thedriverreadsapproximately‐12VDCusingthevoltmeterfunctionontheoscilloscope,thisgapvoltagecorrespondsto
about60milson4140seriessteel.TomeasurethegapvoltagewiththeScopeMetersimplydisconnecttheChannelABNC
Cable,attachtheBananatoBNCAdapterandplugintothevoltageinputconnectors.Takenoteofthepolaritywhenusing

Inordertocollecttherunoutmeasurementtheshaftneedstoberotatedonshaftsupportblockseitherbyhandorby


Step1:

Step2:
AdjusttheProximityProbesDCgapvoltagefora10to12VDCoutput.
Step3:
AdjusttheOpticalSensorsoitdetectsthereflectivetapeoneachshaftrevolution.
Step4:Note–Theshaftmustberotatingfromthisstepforward.

Step5:
WhentakingtheRunoutmeasurementtheScopeMetershouldbesettoshownomorethanthreeshaft

RunoutReduction:
DiamondBurnishing
Adiamondburnishingtoolisusedtoworktheshaftsurfaceintoauniformfinish.
Degaussing
Residualmagnetisminashaftcancausemajorelectricalrunoutandcancauseunstablerunoutreadings.Itis
necessarytomeasurethemagnetismtoensurethatitisnotover2.0gaussoriftheareahasvariationsover1.0
gauss.Ifeitherisfoundtheshaftshouldbedegaussed.TheCMCP810SeriesRunoutKitcanbesuppliedwiththe
optionalGaussMeter.
FurtherMachining
Iftheamountofrunoutcannotbereducedwithadiamondburnishingtoolthenthetargetareacanbereground.
Polishing
Similartodiamondburnishingbutnotashighlyeffective.

ProximityProbeSensitivitywithAlternateMaterials:
AllstandardProximityprobesarecalibratedto4140seriessteel.Whenmeasurementsneedtobetakenondifferentshaft
materialsthetrueProximityprobesensitivityneedstobeknowninordertocalculatetheproperelectricalrunoutreading.
Tomeasuretheprobessensitivitywithspecificmaterialsfollowthestepsbelow.

Step1:
Usingplasticfeelergauges,orothernon‐metallicmaterials,placea60milthickpieceofmaterialbetweentheprobetipand
theshaftandmeasurethemillivoltoutputfromthedriver.Recordthis
voltage.

Step2:
Adda10milthickpieceofmaterialontopofthe60milpieceand
measuretheoutputdriver.Recordthisvoltage.

Step3:
Adda5milthickpieceofmaterialontopofthe60miland10milpieces
andmeasuretheoutputfromthedriver.Recordthisvoltage.

Step4:
Takethetotalmeasurementinmillivolts(mV)anddivideby15.Thisistheprobessensitivitytobeusedforcalculatingthe
totalrunoutwiththatspecificmaterial.
Ex.15mils=1350mV
1350÷15=90mV/mil
ProximityProbeConformanceCheck:
AllProximitySystems(Probe,CableandDriver)shouldbetestedeveryonceinawhileto
ensuretheprobeisstilloperateswithinitsspecifiedrange.Thiscanbedonebyusinga
CMCP610StaticCalibrator(soldseparately),‐24VDCPowerSupplyandaDigitalVoltMeter.
TheProbeisinstalledinthetesterwiththetargetsetagainsttheProbetip.The
micrometerwithtargetattachedisthenrotatedawayfromtheProbein0.005"or5mil
increments.Thevoltagereadingisrecordedandgraphedateachincrement.TheCMSS601
Calibratorwillproduceavoltagechangeof1.0VDC+‐0.05VDCforeach5milsofgap
changewhilethetargetiswithintheSystemslinearrange.
