GeneralOperation
Theory of Operation
Thesystemdescribedbelowmeasuresthethermovoltage(SeebeckVoltage)ofmetalsandsemiconductors.  It
alsoprovidestheuserwiththeopportunitytostudythetemperaturedependenceoftheSeebeckVoltagefor
different
 materials.BelowisapictureoftheSeebeckStagewhichisattachedtothecoldstageoftheMMR
refrigerator.


TheoryofOperation
TheSeebeckStagehastwopairsofthermocouples:oneofcopperandametalwithknown
properties,andtheotherpairofcopperandametalwithpropertiestobedetermined.Oneofthe
junctionsineachpairisconsideredareferencejunction,andtheothertheworkingortemperature
modulatedjunction.TheStagealsohasacomputercontrolledheater,locatedclosetotheworking
junctionsofeachpair,andremotefromthereferencejunctions.Thisheateriscontrolledbythe
MMRProgrammableSeebeckControllerSB1000.TheSeebeckstageisattachedtothecoldstage
ofanMMRrefrigerator,whichprovidesagivenstabletemperatureforthemeasurement.The
MMRColdstageiscontrolledbytheMMRK20000DigitalTemperatureController.TheSeebeck
Stagehastwooutputs:V1andV2,whicharemonitoredbyacomputerthroughtheSB1000.


Theprincipleofoperationisthefollowing:assumethatallfourthermocouplesareatthesame
temperature.ThenV1andV2willbezerobecauseeachmemberofeachpairofthermocouples
compensatesthevoltageoftheother.Ifpowerisappliedtotheheater,thenatemperature
differencewillbecreatedbetweentheworkingandthereferencejunctionsbecausetheyare
locatedatdifferentdistancesfromtheheater.Asaresult,thermovoltageswillbegeneratedin
eachpairgivingnonzerooutputvoltagesVIandV2.Thesearegivenby:
 (1).V1=ε1∆T(P)and
 (2).V2=ε2∆T(P)

Whereε1andε2arethespecificthermo‐voltagesofthesampleandknownthermocouples
respectively,andΔT(P)isthetemperaturedifferencebetweentheworkingandthereference
junctionscreatedbyapplyingpower(P)tothecomputercontrolledheater.Weexpect,thatthe
temperaturedifference ΔT(P)willbethesameforbothpairsbecausethestagehasasymmetrical
shape.Thevalueofthespecificthermo‐voltageoftheunknownjunctionisthen:
(3).ε1=ε2V1/V2

GeneralOperation

However,oneshoulduseasmalltemperaturedeviationΔTinordertoobtainrepresentativedata
inthetemperaturedomain.Therefore,thevaluesofV1andV2willalsobesmall.Becauseofthis,
adirectmeasurementwillnotgivehighaccuracybecauseofinstrumentalerrors,andany
undesiredthermo‐voltageeffectsfromwires,connectors,etc.Theseeffectscancreatesubstantial
offsetvoltageswhich,inadditiontothetemperaturedriftsandoffsetsoftheinputamplifiers,can
contributeamajorsourceofmeasurementerror.Thesecanbeeliminated,however,bytaking
measurementsattwodifferenttemperatureoffsets,usingtwodifferentpowersettings,andthen
usingthedifferencesignal.Weshowthisasfollows;therealvaluesofV1andV2acquiredbythe
SB1000aregivenby:
 (4).V1(P1)=ε1∆T(P1)+∆V1and
 (5).V2(P2)=ε2∆T(P2)+∆V2

WhereΔV1andΔV2aretheinstrumentandextraneousthermaloffsetvoltagesdiscussedabove,
andP1isthepowerappliedtotheheateratthefirstmeasurementpoint.Now,iftheheaterpower
ischangedtoanewvalueP2,weobtainasecondpairofvaluesforV1andV2:
 (6).V1(P2)=ε1∆T(P2)+∆V1and
 (7).V2(P2)=ε2∆T(P2)+∆V2

TheoffsetvoltagesΔV1andΔV2canbeassumedtobeindependentofpowerP,becauseonlythe
temperatureintheimmediateneighborhoodofthereferenceandsamplejunctionschange,not
thosewheretheseotheroffsetvoltagesoriginate.

Subtractingequations(6)and(7)from(4)and(5),respectively,weobtainthetruevalueofε1from
thefollowing:

 (8).ε1=ε2{V1(P1)‐V1(P2)}/{(V2(P1)‐V2(P2)}

(8)doesnotincludeΔV1andΔV2.Theoffsetshavebeenremoved.

Certainhardwareandsoftwareprecautionshavealsobeenimplementedtoeliminateanypossible
electricalcouplingbetweentheheaterandmeasurementcircuitsaswell.
