Yog lawm,thermocouple hlautuaj yeem txuas ntxiv, tab sis ob peb yam tseem ceeb yuav tsum tau txiav txim siab los xyuas kom meej qhov ntsuas kub thiab qhov kev ntseeg tau ntawm lub cev. Kev nkag siab txog cov ntsiab lus no yuav tsis tsuas yog pab koj txiav txim siab paub tab tab sis kuj qhia txog ntau yam thiab kev hloov pauv ntawm peb cov khoom zoo thermocouple hlau.
Thermocouples ua haujlwm raws li Seebeck nyhuv, qhov kub ntawm qhov sib txawv ntawm ob cov hlau tsis sib xws ua rau lub zog hluav taws xob (EMF). Thaum txuas cov xov hlau thermocouple, nws yog ib qho tseem ceeb uas yuav tsum siv cov xov hlau txuas ntxiv ua los ntawm cov khoom siv nrog cov khoom siv hluav taws xob zoo sib xws rau cov khoom siv thermocouple qub. Qhov no ua kom ntseeg tau tias EMF tsim los ntawm qhov kub thiab txias raws li qhov kev ncua ntev tseem nyob nrog cov yam ntxwv ntawm cov thermocouple qub.
Peb lub tuam txhab muaj ntau yam ntawm high-precision thermocouple extension xov hlau. Cov xov hlau txuas ntxiv no yog tsim los rau cov qauv kev lag luam nruj, kom ntseeg tau tias qhov kub thiab txias thiab qhov teeb meem tsawg tsawg. Lawv muaj nyob rau hauv ntau hom, xws liJ, K, T, E, S, thiabR, uas tuaj yeem ua tau zoo sib xws nrog ntau hom thermocouple hauv khw. Cov ntaub ntawv siv hauv peb cov xov hlau txuas ntxiv yog cov resistant rau oxidation thiab corrosion, muab kev ruaj ntseg ntev hauv qhov chaw ua haujlwm sib txawv.
Thaum nws los txog rau cov txheej txheem kev ua haujlwm tshwj xeeb ntawm kev txuas ntxiv cov xaim thermocouple, ua ntej, koj yuav tsum txiav cov thawj thermocouple xaim ntawm qhov tsim nyog nrog lub tshuab ntse ntse. Tom qab ntawd, strips txog 1 - 2 cm ntawm cov txheej rwb thaiv tsev ntawm qhov kawg ntawm ob qho tib si thawj cov hlau thiab cov hlau txuas ntxiv siv cov hlau strippers. Tom ntej no, ntswj cov hlau liab qab ntawm cov hlau qub thiab cov hlau txuas ntxiv ua ke kom ruaj khov, kom ntseeg tau tias muaj hluav taws xob zoo. Tom qab ntawd, siv ib tug soldering hlau thiab solder rau solder lub twisted ib feem, pab txhawb kev sib txuas kev ntseeg tau. Thaum kawg, npog qhov sib koom ua ke nrog cov cua sov - shrink tubing thiab siv cov cua sov nrog rab phom cua sov kom shrink lub raj, muab rwb thaiv tsev thiab kev tiv thaiv.
Rau cov cuab yeej tshwj xeeb thiab cov ntaub ntawv uas yuav tsum tau, dhau li hais txog cov hlau txiav, cov hlau strippers, cov hlau soldering, solder, thiab cua sov - shrink tubing, koj kuj yuav xav tau ib tug multimeter los xyuas cov hluav taws xob txuas ntxiv ntawm cov xaim txuas ntxiv ua ntej kev teeb tsa. Peb lub tuam txhab tuaj yeem muab cov khoom siv ua tiav nrog rau cov khoom siv thermocouple thiab cov khoom siv txuas ntxiv, txuag koj cov teeb meem ntawm kev muab lawv cais.
Tom qab txuas lub thermocouple hlau, calibration yog tsim nyog los xyuas kom meej qhov ntsuas kub. Ib txoj hauv kev calibration feem ntau yog siv qhov chaw ntsuas kub. Muab cov thermocouple hlws ris rau hauv qhov chaw paub - qhov kub thiab txias, xws li qhuav - thaiv calibrator lossis lub cub tawg nrog qhov kub thiab txias. Tom qab ntawd, ntsuas qhov tso zis voltage ntawm lub thermocouple siv lub precision digital multimeter. Sib piv qhov ntsuas qhov ntsuas hluav taws xob nrog tus qauv ntsuas hluav taws xob - qhov ntsuas kub sib thooj rau hom thermocouple. Yog tias muaj qhov sib txawv, kho qhov ntsuas ntsuas lossis ntsuas qhov ntsuas raws li tus nqi sib txawv. Peb pab neeg muab kev pab txhawb nqa tuaj yeem muab cov lus qhia ntxaws ntxaws los xyuas kom meej tias koj tuaj yeem ua tiav cov txheej txheem calibration smoothly.
Ntxiv nrog rau kev siv cov kab txuas ntxiv kom raug, kev txhim kho kom raug kuj tseem ceeb. Tsis zoo ntsia extensions yuav qhia ntxiv kuj, suab nrov, thiab yuam kev. Peb cov khoom tuaj nrog cov lus qhia ntxaws txog kev teeb tsa, thiab peb pab pawg txhawb nqa kev pabcuam yeej ib txwm npaj los pab koj nrog txhua qhov kev teeb tsa - cov lus nug ntsig txog.
Lwm qhov zoo ntawm peb cov khoom siv thermocouple yog lawv cov kav ntev. Ua los ntawm cov ntaub ntawv qib siab, lawv tuaj yeem tiv taus ib puag ncig hnyav, suav nrog qhov kub siab, av noo, thiab tshuaj lom neeg raug. Qhov no txhais tau hais tias txawm tias thaum txuas ntxiv, peb cov xov hlau thermocouple yuav tswj kev ua haujlwm ruaj khov nyob rau lub neej ua haujlwm ntev.
Hauv kev xaus, txuas ntxiv thermocouple hlau yog ua tau, thiab nrog peb cov khoom siv hluav taws xob thermocouple txhim khu kev qha thiab cov khoom siv txuas ntxiv, nrog rau cov kev pabcuam txhawb nqa, koj tuaj yeem ntseeg siab nthuav koj cov ntsuas kub. Txawm hais tias nws yog rau cov ntawv thov kev lag luam, kev tshawb fawb txog kev tshawb fawb, lossis lwm qhov chaw, peb cov khoom muab qhov tseeb, ruaj khov, thiab kev daws teeb meem ntev rau koj qhov kub thiab txias - kev xav tau.
