(3) Muaj av ntau dhau ntawm cov npoo ntawm cov raj thermocouple tiv thaiv raj .
(4) txoj kab ntsuas yog luv-circuited (thermocouple thiab them nyiaj hlau) .
(5) thermocouple Circuitle tau tawg .
(6) Lub davhlau ya nyob twg yog xoob.
Kev daws:
(1) Hloov cov thermocouple .
(2) hloov cov kev teeb tsa chaw thiab txoj kev teeb tsa .
(3) ntxuav nws .
(4) Hloov cov rwb thaiv tsev ntawm cov luv hluav taws xob .

Txhaum kev kuaj qauv ntawm txoj kev thermocouple
Tom qab ntsuas yog qhov tseeb tau raws li cov twj ntaub ntawv qhia txog qhov ntsuas kub, thiab tom qab ntawd cov cuab yeej ntsuas kub ntawm qhov ntsuas kub, thiab tom qab ntawd cov cuab yeej ntsuas kub ntawm lub ntsuas kub, thiab tom qab ntawd cov cuab yeej ntsuas kub ntawm qhov ntsuas kub, thiab tom qab ntawd cov cuab yeej ntsuas kub "{{{0000" {{000 ", nws txhais tau tias cov tswv yim ntawm lub twj paj nruag yog qhov yuam kev thiab cov kev ntsuas hauv qab no yuav tsum tau ua:
A) Tshem tawm cov thermocouple ntawm lub ntsuas kub ntawm lub ntsuas phoo, nws txhais tau tias cov khoom siv sab hauv nws txhais tau tias cov lus tawm xaus ntawm lub ntsuas tau puas thaum lub sijhawm thauj mus los, thiab ntsuas yuav tsum tau hloov {}}}
B) Tshem tawm cov thermocouple ntawm cov ntsiab lus saum toj no thiab hloov pauv ntawm lub ntsuas cua sov ntawm lub ntsuas cua sov ntawm qhov ntsuas cua sov Yog tias qhov xwm txheej saum toj no tseem muaj, nws txhais tau tias cov lus tawm xaus ntawm qhov ntsuas tau puas thaum lub sijhawm thauj mus los, thiab ntsuas yuav tsum tau hloov.
C) Tshem tawm cov cuav thermocouple los ntawm kev ntsuas, nws txhais tau tias yog qhov kev sib tw ntawm lub thermocouple yog qhib, thiab hloov cov thermocouple ntawm tib hom}}} Txwv tsis pub, muaj ib qho tsis muaj tseeb tus nqi, uas txhais tau tias muaj teeb meem nrog cov lus qhia xaus ntawm lub ntsuas thiab ntsuas yuav tsum tau hloov {}}}
D) Cov kab hlau yog qhov tseeb raws li cov ntsuas hluav taws xob daim duab {{}}}}}}} nyuam qhuav hloov lawv dua.
E) Thaum cov xov hluav taws xob yog qhov tseeb, qhov ntsuas kub tshwm sim ntawm cov ntsuas kub ntawm qhov ntsuas kub ntawm qhov ntsuas kub (ºC) thiab cov mv) tus nqi ntawm thermocouples xws li as thermocouple graduations B, S, K, and E, under the same temperature (ºC), the millivolt value (MV) generated by the B graduation is the smallest, the S graduation is the second smallest, the K graduation is the largest, and the E graduation is the largest. The judgment is made based on this principle.
