Txhaum kev kuaj qauv ntawm txoj kev thermocouple
Tom qab ntsuas yog qhov tseeb wired raws li cov ntsuas hluav taws xob kos duab thiab muab cov ntsuas ntawm cov ntsuas kub, thiab tom qab ntawd cov cuab yeej ua ntej ntawm cov ntsuas kub ntawm cov ntsuas kub ntsuas kub. Yog tias cov raj digital ntawm lub twj paj nruag tsis qhia qhov kub thiab txias rau cov khoom cua kub, "{{{{1} {{1} 000
A) Tshem tawm cov thermocouple los ntawm cov twj ntsuas kub thermocouple xaus ntawm qhov ntsuas, thiab tom qab ntawd siv ib qho hlau los luv luv ntawm lub thermocouple cov lus qhia xaus ntawm lub ntsuas. Thaum lub zog yog nyob, yog tias tus nqi tshwm sim los ntawm cov raj digital ntawm lub ntsuas yog qhov kev sib txuas sab hauv, nws txhais tau tias kev sib txuas sab hauv, thiab tib lub thermocouple yuav tsum tau hloov. Yog tias qhov xwm txheej saum toj no tseem muaj, nws txhais tau tias cov lus tawm xaus ntawm lub ntsuas tau ua puas thaum lub sijhawm thauj mus los, thiab ntsuas yuav tsum tau hloov.
B) Tshem tawm cov thermocouple ntawm cov ntsiab lus saum toj saud Tom qab lub zog yog nyob rau, thaum cov raj digital ntawm thawj qhov kev sib txuas ntawm qhov kub thiab txias, nws txhais tau tias kev qhib sab hauv ntawm lub thermocouple yog qhib, thiab tib lub thermocouple yuav tsum tau hloov. Yog tias qhov xwm txheej saum toj no tseem muaj, nws txhais tau tias cov lus tawm xaus ntawm lub ntsuas tau ua puas thaum lub sijhawm thauj mus los, thiab ntsuas yuav tsum tau hloov.
C) Tshem tawm cov cuav thermocouple los ntawm cov twj paj nruag, teeb tsa ntau ntau rau Ohm (R) * 1 txoj haujlwm, thiab siv ob txoj haujlwm ntawm ntau qhov kawg ntawm thermocouple. Yog tias cov nqi tiv thaiv tau tso tawm ntawm cov pulultimeter yog qhov loj, nws txhais tau tias kev sib txuas sab hauv ntawm thermocouple yog qhib, thiab hloov cov thermocouple ntawm tib hom. Txwv tsis pub, muaj qee yam tseem ceeb tus nqi, uas txhais tau tias muaj teeb meem nrog lub tswv yim xaus ntawm qhov ntsuas thiab ntsuas yuav tsum tau hloov.
D) Cov hlau hluav taws xob yog qhov tseeb raws li cov ntsuas hluav taws xob kos duab. Yog tias qhov ntsuas tau siv rau, cov kab loj ntawm cov leeg digital rau ntawm qhov ntsuas pom tias yog qhov ntsuas tsis zoo "" thiab "" txuas nrog cov twj paj nruag sib txuas. Cia li hloov lawv dua.
E) Thaum cov kav hlau yog qhov tseeb, qhov ntsuas kub tshwm sim ntawm cov kab loj ntawm cov leeg digital ntawm cov ntsuas txawv ntawm qhov ntsuas kub tiag tiag los ntawm 30ºC. Ntau qhov sib txawv, nws txhais tau tias qhov kev kawm tiav ntawm qhov ntsuas tsis yog nrog cov lej ntawm cov thermocouple. Raws li cov kev sib raug zoo sib xws ntawm qhov kub (ºC) thiab mv) tus nqi ntawm b, thiab e, nyob rau hauv tib tus kub (ºC) yog qhov tsawg tshaj plaws, thiab e-xyoo yog qhov loj tshaj plaws. Kev txiav txim siab tau ua raws li txoj ntsiab cai no.
