Thermocoples hauv series? Thermocoples hauv parallel?

Peb paub tias thermocouples yog ua los ntawm ob cov ntaub ntawv sib txawv nrog cov khoom sib txawv thermoelectric muaj zog. Thaum muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias thiab txias, nws ua rau hluav taws xob hluav taws xob tsis muaj zog heev. Nyob rau hauv ib txwm muaj xwm txheej, qhov no yuav txuas nrog tus sau los ntawm lub transmitter, thiab ib qho kev sojntsuam tsuas yog tso zis ib qho ntsuas kub.

Tab sis qee lub sijhawm muaj qee cov ntawv thov tsis txaus ntseeg, uas yog, cov koob thiab kev sib txuas sib txuas ntawm cov thermocoples. Dab tsi teeb liab yog tso zis tom qab series lossis parallel txuas? Nws yog ib qho yooj yim to taub yog tias peb hais txog qhov thermocouple raws li qhov dc voltage tau qhov chaw.

Thaum lub thermocouple txuas nrog hauv cov koob nrog tus qauv zoo thiab tsis zoo, nws zoo li cov roj teeb qhuav hauv cov ntawv. Nws cov khoom tawm tag nrho yog qhov suav ntawm qhov tseem ceeb ntawm cov nqi hluav taws xob, uas yog, cov ntsuas kub yog qhov tseeb ntawm qhov ntsuas kub ntau.

Parallel kev sib txuas ntawm thermocouples txhais tau tias qhov zoo ntawm txhua qhov thermocouples tau txuas ua ke rau txhua qhov thermocouples tau txuas ua ke. Kho cov thermocouple raws li DC voltage tau nrog sab hauv kev tiv thaiv. Qhov kawg ua rau cov zis sib txuas tau yog qhov muaj txiaj ntsig nruab nrab ntawm txhua qhov hluav taws xob, qhov ntawd yog, cov khoom siv sib txuas yog qhov ntsuas kub nruab nrab ntawm txhua qhov thermocouple probes.

Cov txiaj ntsig saum toj no tsuas yog kwv yees kwv yees thiab yuav tsis muaj tseeb heev. Vim tias muaj qhov sib txawv ntawm thermococe. Thaum siv nyob rau hauv tiag teb, txawm hais tias nyob rau hauv series lossis pawm, tib hom thermoco plab yuav tsum tau siv kom tau txais cov txiaj ntsig ze rau txoj kev suav ua theoretical.
