Kev siv thermocouples hauv kev tsim khoom hauv ntau yam kev lag luam

Thermocouples yog siv los ntsuas cua sov sov. Thermocouples nrog cov lus teb cov ntsiab lus yog tsuas yog xaiv raws li lub hom phiaj kub. Yog lawm, nws tseem yuav tsum tau txiav txim siab seb qhov chaw ntsuas yog txo lossis oxidizing. Txawm li cas los xij, yog siv lub thermored thermocouples siv, Kuv tsis tau xav txog qhov cuam tshuam ntawm redox cua nyob rau lub neej thiab ntsuas qhov tseeb ntawm thermocouples. Cov cai yuav tsum tau ua ib nyuag nqaim. Feem ntau cov cua sov yuav tsum tau txuas nrog ob lub thermocouples. Tsawg kawg ib ntawm lawv yuav tsum siv rau kev tswj kom kub thiab lwm yam rau sau cia. Vim tias peb cov txheej txheem ua yuav tsum tau ua kom tiav, thaum ntsib lub cub hluav taws loj (ntau tshaj 5 meters ntev), nws yuav tsum muab faib ua ob peb qho chaw ntsuas kub rau kev ntsuas ywj siab thiab tswj. Piv txwv li, cov txheej txheem sab saud, nruab nrab thiab sab hauv qab, thiab lwm yam. Ntsuas cov hluav taws xob ua kom sov tsis tu ncua. Ntawd yog, ntau yam thermocouples (lossis lwm qhov kev pab cuamyees hauv kev sim ua kom ntsuas qhov kub ntawm lub cub tawg thaum lub sijhawm thiab lwm yam. Ntawd yog, txawm hais tias ntsuas kub tau ntsuas qhov ntsuas kub tuaj yeem sawv cev qhov ntsuas kub tiag tiag, thiab ntau yam kev ntsuas ua rau txhua tus nqi. Thermocouples yog tsuas yog siv rau kev ntsuas thiab ntsuas. Thermocouples yog cov twj tseem ua thawj uas hloov qhov kub thiab txias rau hauv hluav taws xob muaj peev xwm. Qhov no tsis muaj zog hluav taws xob muaj peev xwm kis tau rau cov cuab yeej theem nrab rau kev ua tiav, tso saib lossis luam ntawv. Cov twj paj nruag theem nrab tau muab faib ua cov analog thiab digital hom. Tam sim no lawv mas cov digital. Kev siv thermocouples hauv kev tsim khoom hauv ntau yam kev lag luam

Qhov ntsuas hluav taws xob txias txias txias xaus, uas suav nrog lub tshuab hluav taws xob kub siab tshiab tingry Tus txheej txheem ua hauj lwm ntawm thermocouple yog los tsim lub peev xwm hluav taws xob sib txawv raws li qhov sib txawv ntawm qhov kub thiab txias kawg thiab txias. Vim tias qhov ntsuas kub ntawm qhov kawg yog feem ntau tsis 0 degree thaum ntsuas kev ntsuas tiag tiag, ntsuas hluav taws xob yuav tsum tau ntsuas kub. Kev Ntsuas Hluav Taws Xob Thermocouple yog raws li hauv qab no: E (t, 0} {{}, 0)

Qhov twg, e (t {{{{0} {{{{} sawv cev 0 degree. Hauv qhov ntsuas kub ntawm cov teb sov, txij li qhov kub ntawm qhov txias txias kawg ntawm thermocouple feem ntau tsis}} degree, yog kev ntsuas thermoelectric muaj peev xwm yog e (t} {7}}). Yog tias koj xav ntsuas qhov thermoelectric muaj peev xwm e (t, {{8} {{{}, {}}) yuav tsum tau thaum lub sij hawm txias tsis yog 0 degree. Ntxiv mus, cov yam ntxwv ntawm cov nyiaj them tuaj yeem hloov nrog qhov txias txias yuav tsum muaj nrog cov thermocouple, yog li kom tau txais cov nyiaj them zoo. Nov yog daim duab txheej txheem hluav taws xob rau thermocouple txias qhov kawg them. Qhov ntsuas kub Sensor Tual .. Lub tshuab hluav taws xob tawm los ntawm Tona Los ntawm Tonapingor los ntawm lub resistor thiab tom qab ntawd amplified los ntawm kev sib raug zoo, uas yog EN sib raug rau K-hom thermocouple.
