Txoj kev sib txuas ntawmthermocoupleyog raws li nram no:
Thermocouples feem ntau muab faib ua qhov zoo thiab tsis zoo. Thaum xaim, koj yuav tsum txuas ib qho kawg ntawm thermocouple mus rau lwm kawg. Lub terminals ntawm lub thawv hlws ris yog cim nrog cov cim zoo thiab tsis zoo. Feem ntau hais lus, lub davhlau ya nyob twg cim nrog "+" yog tus ncej zoo, thiab lub davhlau ya nyob twg nrog "-" yog tus ncej tsis zoo.
Thaum xaim, txuas cov khoom siv hluav taws xob zoo rau cov cua sov ntawm lub thermocouple thiab qhov tsis zoo electrode rau lub davhlau ya nyob twg ntawm qhov chaw txias. Qee qhov thermoco yuav tsum tau txuas nrog cov xov hlau nyiaj. Qhov zoo thiab tsis zoo ntawm cov xov hlau them yuav tsum sib haum rau qhov zoo thiab tsis zoo ntawm qhov thermocouple. Nyob rau tib lub sijhawm, kev sib txuas ntawm cov cua sov ntawm qhov thermocouple thiab cov nyiaj them nqi yuav tsum tau ua insulated nrog insulating cov ntaub ntawv.
Tsis tas li ntawd, cov zis tawm ntawm cov thermocouple yog qhov me me, thiab nws yuav tsum tau txuas nrog ntsuas ntsuas cov ntaub ntawv los nyeem cov ntaub ntawv. Kev ntsuas ntsuas feem ntau suav nrog cov ntsiab lus kub, thiab lwm yam Cov zis tawm ntawm lub tswv yim xaus kev ntsuas, thiab ua ntsuas thiab tso tawm kom pom.
Nws yuav tsum tau sau tseg tias txoj kev siv hluav taws xob ntawm thermocoolles tej zaum sib txawv raws li cov qauv sib txawv thiab cov qauv tshwj xeeb. Yog li ntawd, nyob rau hauv cov ntawv thov tiag tiag, kev siv hluav taws xob yuav tsum tau nqa tawm raws li qhov tshwj xeeb thermocouple qauv thiab cov ntaub ntawv sib dhos. Nyob rau tib lub sijhawm, txhawm rau kom muaj kev nyab xeeb, nws kuj yog qhov tsim nyog los them sai sai rau qhov tseeb thiab kev ntseeg tau ntawm cov xaim kom tsis txhob muaj kev huam yuaj.
