Kev tswj qhov kub ntawm thermocoples

Thermocouple yog ib hom ntsuas kub hnov. Nws ntsuas ncaj qha kub thiab hloov cov teeb liab kub rau hauv qhov kub thiab txias ntawm cov twj ntsuas hluav taws xob (theem nrab seev). Lub hauv paus ntsiab lus ntawm kev ntsuas kub yog tias ob tug cwj pwm nrog cov lej sib txawv ua daim ntawv kaw circuit Court. Thaum muaj qhov ntsuas kub thiab txias ntawm ob qho kawg, tam sim no yuav ntws los ntawm Circuit Court, thiab yuav muaj ib lub zog hluav taws xob - thermoelectric quab yuam - nruab nrab ntawm ob xaus,
Qhov no yog qhov thiaj li hu ua cov nyhuv pom. Thaum ib qho khoom siv thib peb hlau txuas nrog CALCOCOULE Circuitle, ntev li ntev tau qhov kub ntawm cov khoom siv yog tib yam, yuav tsis muaj kev cuam tshuam los ntawm kev sib txuas ntawm cov hlau thib peb mus rau hauv Circuit Court. Yog li ntawd, thaum siv thermocouples rau kev ntsuas kub, ntsuas ntsuas ntsuas tuaj yeem txuas nrog ntsuas cov peev xwm ntawm thermoelectric tuaj yeem txiav txim siab.
Ob homogeneous tus cwj pwm nrog cov sib xyaw sib txawv yog cov hluav taws xob sib txawv yog qhov kub siab tshaj li qhov kev ua haujlwm kawg thiab qhov kub qis kawg, uas feem ntau yog nyob ntawm qhov kub tsis tu ncua. Tsim cov lus ntsuas hluav taws xob thermocouple raws li kev sib raug zoo ntawm thermoelectric muaj peev xwm thiab kub; Lub rooj ntsuas hluav taws xob yog tau nyob hauv qhov xwm txheej ntawm qhov xaus pub dawb xaus ntawm {{0} degree muaj cov rooj ntsuas sib txawv.

Ua haujlwm ua haujlwm ntawm thermocouple kub sensor

Ob tug neeg uas muaj sib txawv (hu ua Thermocouple xov hlau lossis thermoelectric electrodes) tau txuas ntawm ob qho kawg los ua ib qho Circuit Court. Thaum qhov kub ntawm lub zog sib txawv yog qhov sib txawv, uas siv hluav taws xob tau tsim tawm hauv Circuit Court, uas yog hu ua thermielectric nyhuv, thiab lub zog hluav taws xob hu ua thermoelectric peev xwm. Thermocoples siv cov ntsiab cai no rau kev ntsuas kub, qhov twg yog hu ua kev ntsuas qhov kawg (tseem hu ua qhov kawg); Txuas qhov txias txias rau cov khoom siv tawm los yog sib piv, thiab cov twj paj nruag tso tawm yuav qhia tau tias yog thermoelectric peev xwm tsim los ntawm thermocouple.

Thermocoples yog cov zog hloov ua tau tiag tiag uas hloov lub zog thermal no rau hauv hluav taws xob lub zog thiab ntsuas kub siv cov peev txheej thermoelectric muaj peev xwm. Hais txog lub peev xwm thermoelectric ntawm thermocouples, cov teeb meem nram qab no yuav tsum tau sau tseg:
1. Qhov ntau ntawm cov thermoelectric peev xwm tsim los ntawm ib qho thermocouple tsis muaj feem xyuam rau qhov ntev thiab cov khoom ntawm cov khoom siv thermocouple thiab qhov kub ntawm qhov sib txawv;

2. Lub peev xwm thermoelectric yog qhov sib txawv hauv qhov kub thiab txias ntawm qhov xaus ntawm qhov sib txawv ntawm qhov txias txias thiab ua haujlwm kawg ntawm thermocouple;

3. Tom qab cov muaj pes tsawg leeg ntawm ob lub qhov hluav taws xob thermocouple tau txiav txim siab, qhov ntau ntawm cov thermoellets tsuas yog cuam tshuam rau qhov kub ntawm lub thermocouple; Yog hais tias qhov ntsuas kub ntawm qhov txias txias ntawm thermocouple tseem tas mus li, lub thermoelectric muaj peev xwm nkag mus rau hauv lub thermocouple tsuas yog ib tus nqi ua haujlwm kub.

Kev xaiv ntawm kev ntsuas thermocouple thiab ntsuas kub ntau yam

Ob yam khoom sib txawv ntawm cov ntaub ntawv sib txawv lossis cov semiconductors a thiab b yog welded ua ke los ua ib qho kev kaw Circuit Court, raws li qhia hauv daim duab. Thaum muaj qhov sib txawv ntawm ob qho tib si txuas cov ntsiab lus 1 thiab 2 ntawm kev coj ua A thiab B, lub zog hluav taws xob tau tsim los ntawm lawv, uas ua rau muaj qee qhov ntau ntawm cov hluav taws xob. Qhov tshwm sim no hu ua thermoelectric nyhuv. Thermocouples ua haujlwm los ntawm kev siv cov nyhuv no.

Kev xaiv ntawm thermocouples yuav tsum tau raws cov kev txiav txim siab ntawm kev ua haujlwm ntau, tsim nyog qhov tseeb, kev ua haujlwm ntawm cov khoom ntsuas, kev kawm tau, thiab cov nyiaj txiag.

1. Kev xaiv cov cua rau S-hom thiab B-hom thermocoiding yog tsim nyog rau muaj zog oxidizing thiab t-hom thermocoupizing thiab t-hom thermoidizing thiab txo cov cua nab kuab thiab txo cov cua nab kuab. Yog tias lub raj tiv thaiv nrog cov huab cua zoo yog siv, cov cai rau cov cua tsis nruj heev.

2. Kev xaiv qhov ntsuas qhov tseeb thiab ntsuas kub ntau feem ntau yog raws li kev siv B-hom thermocouples thaum qhov kub thiab txias thiab qhov tseeb yog qhov tseem ceeb; Qhov yuav tsum tau ua rau qhov raug yog tsis yog, thiab cov cua tso cai rau kev siv lub tungsten rhenium thermoco thermocouples. Feem ntau, tungsten rhenium thermocots yog xaiv rau qhov kub siab tshaj 1800 degree; S-hom thermocouples thiab n-hom thermoounles muaj rau siv nyob rau ntawm qhov kub kub txij 1000 txog 1300 degree, uas yuav tsum muaj qhov tseeb; K-hom thiab n-hom thermocouples feem ntau siv qis dua 1000 degree, thaum e-hom e-hom e-hom e-hom ntawv thermocoup feem ntau yog siv qis dua 400 degree; Ntawm 250 degree thiab cov ntsuas kub tsis zoo, T-hom thermocouples feem ntau siv. Ntawm tsawg kub, T-hom thermocouples yog ruaj khov thiab muaj qhov tseeb.

3. Kev xaiv ntawm durability thiab thermal rawm|Thermocouples nrog cov hlau loj dua muaj cov durability hlau loj dua, tab sis qeeb qeeb. Rau thermocouples nrog loj dua tshav kub muaj peev xwm, cov lus teb qeeb qeeb. Thaum ntsuas ntsuas kub nrog cov gradients loj, tswj qhov kub yog tsis zoo thaum ntsuas kub. Nws yuav tsum muaj lub sijhawm teb sai thiab muaj qee qib ua haujlwm ruaj khov, yog li xaiv cov menyuam roj hmab yog qhov tsim nyog dua.

4. Kev xaiv ntawm thermocots raws li cov khoom thiab cov xeev ntawm ntsuas ntsuas

Qhov ntsuas kub ntawm vibrating cov khoom, cov khoom siv vibrating, thiab cov hlab ntsha siab yuav tsum muaj cov tshuaj lom neeg muaj zog, thiab cov rwb thaiv tsev siab yuav tsum muaj nyob rau hauv kev cuam tshuam hluav taws xob.

5. Kev ceev faj

Cov ntxig ntxig ntawm qhov thermocouple yog tsawg heev: nws yuav tsum tsis txhob tsawg tshaj li 8-10 lub cev sab nraud ntawm nws cov khoom tiv thaiv (tshwj tsis yog rau cov khoom tshwj xeeb)

◆ ThermocoPleco [1] Nominal siab: Feem ntau hais txog lub siab zoo li qub uas lub raj tiv thaiv muaj peev xwm tiv taus thiab tawg ntawm qhov kub ua haujlwm.

◆ Rwbulion Reptance: Thaum cov cua kub huab cua kub yog {{{}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} {hms (voltage 100v). Thermocouples nrog cov thawv ntawv sib xws muaj lub rwb thaiv tsev tsis kam ntawm ntau dua los yog sib npaug ntawm 0.5 MoGohms (Voltage 100v) thaum tus txheeb ze kub yog 93 ± 3 degree

◆ Rwb los teb tsis kam rau qhov kub: rau thermoounce, lub rwb thaiv lwm ob leeg hluav taws xob, yuav tsum muaj ntau dua li cov txiaj ntsig hauv qab no.
