Yuav ua li cas sawv cev thermocouple parameter

Thermocouples yog ib qho kev ntsuas kub uas siv los ntsuas qhov ntsuas kub los ntawm kev ntsuas qhov kub ntawm qhov sib txawv ntawm cov hlau hlau. Txhawm rau piav qhia txog cov yam ntxwv ntawm kev ua haujlwm ntawm cov thermocouples, nws yog ib qho tsim nyog yuav tsum nkag siab txog ntau yam tsis muaj. Yog li, qhov ntsuas ntawm thermocouples sawv cev li cas?
Kev ntsuas kub ntau ntawm cov thermocouples feem ntau yog nyob ntawm cov khoom siv hlau siv, feem ntau suav nrog J, K, T, E hom, thiab lwm yam. Cov sawv cev ntawm ntau yam yog feem ntau raws li tus qauv ntsuas kub, hauv degrees Celsius.
Kev ntsuas ntawm thermocouples yog qhov ntsuas tseem ceeb uas sawv cev rau qhov yuam kev ntawm qhov ntsuas ntsuas thiab qhov ntsuas kub tiag tiag. Feem ntau qhia raws li qhov feem pua ​​​​ntawm qhov kub thiab txias, xws li ± 1 degree lossis ± 0.5%.
Qhov rhiab heev ntawm lub thermocouple nyob ntawm cov khoom thiab qhov ntev ntawm cov hlau hlau. rhiab heev sawv cev rau qhov loj ntawm voltage hloov los ntawm ib chav tsev kub hloov, feem ntau qhia nyob rau hauv millivolts ib degree Celsius.
Lub sij hawm teb ntawm lub thermocouple yog hais txog lub sij hawm txij li thaum lub sensor raug cuam tshuam los ntawm qhov kub thiab txias hloov mus rau thaum lub teeb liab tso zis stabilizes. Tus sawv cev ntawm lub sij hawm teb yog feem ntau qhia nyob rau hauv lub sij hawm luv luv, ntsuas nyob rau hauv vib nas this.
Lub peev xwm ua haujlwm ntawm cov thermocouples hauv qhov chaw kub kub. Feem ntau qhia nyob rau hauv ntsuas kub, nyob rau hauv degrees Celsius.
Kev siv tau zoo ntawm cov thermocouples nyob rau hauv ib puag ncig sib txawv. Feem ntau, yam xws li kev ua haujlwm kub thiab qib kev tiv thaiv yuav tsum tau xav txog.
Hauv cov ntsiab lus, qhov ntsuas tsis tau ntawm cov thermocouples tuaj yeem sawv cev los ntawm cov ntsuas xws li ntau yam, rhiab heev, lub sijhawm teb, qhov kub thiab txias tsis kam, thiab ib puag ncig tsim nyog. Cov kev ntsuas sib txawv txiav txim siab qhov kev ua tau zoo ntawm cov thermocouples hauv cov ntawv thov sib txawv.
1. Qhov tseem ceeb ntawm cov thermocouple tsis
Kev nkag siab txog qhov tsis zoo ntawm cov thermocouples yog qhov tseem ceeb rau kev xaiv kom raug thiab siv cov thermocouples.
Kev nkag siab txog cov thermocouples tuaj yeem pab peb txiav txim siab seb lawv puas tuaj yeem ua tau raws li qhov yuav tsum tau ntsuas, uas yog qhov tseem ceeb tshwj xeeb rau daim ntawv thov kev ntsuas.
Kev nkag siab txog kev ua haujlwm kub ntawm cov thermocouples tuaj yeem txiav txim siab seb lawv puas tsim nyog rau kev ntsuas kub tshwj xeeb.
Nkag siab txog qhov kub thiab txias thiab kev siv ib puag ncig ntawm cov thermocouples yog qhov tseem ceeb rau kev ntsuas nyob rau hauv ib puag ncig tshwj xeeb, xws li kub kub thiab corrosive gases.
2. Kev ceev faj rau xaiv cov thermocouples
Txiav txim siab qhov ntsuas qhov xav tau ntawm cov thermocouples raws li qhov yuav tsum tau ntsuas qhov tseeb, thiab xaiv cov qauv tsim nyog thiab cov khoom siv.
Rau cov xwm txheej uas xav tau kev ntsuas siab, yuav tsum xaiv tus qauv siab dua thermocouple.
Xaiv cov thermocouples nrog kev tiv thaiv kev ua haujlwm raws li qhov tseeb ib puag ncig.
Rau cov kev cai tshwj xeeb xws li kev teeb tsa yooj yim, kev tu yooj yim, thiab lwm yam, thermocouples nrog cov qauv tshwj xeeb yuav tsum raug xaiv.
3. Kev ceev faj rau kev siv cov thermocouple tsis
Ua raws li cov lus qhia kev teeb tsa rau cov thermocouples rau kev teeb tsa kom zoo kom tsis txhob qhia qhov ntsuas qhov yuam kev ntxiv.
Sim tsis tu ncua calibrate thermocouples los xyuas kom meej ntsuas.
Ua tib zoo tiv thaiv cov xov hlau sab nraud ntawm lub thermocouple kom tsis txhob cuam tshuam qhov ntsuas vim kev puas tsuaj los yog lwm yam laj thawj.
Ntxuav lub ntsej muag ntawm lub thermocouple kom raws sijhawm kom tsis txhob muaj cov roj stains thiab cov tshuaj corrosive ntawm lub thermocouple.
Tus sawv cev ntawm cov ntsuas kub ntsuas ntsuas ntsuas ntsuas xws li ntau yam, rhiab heev, lub sijhawm teb, kub tsis kam, thiab kev siv ib puag ncig. Kev nkag siab txog cov kev txwv no yog qhov tseem ceeb rau kev xaiv kom raug thiab siv cov thermocouples. Thaum xaiv thiab siv cov thermocouples, kev txiav txim siab yuav tsum tau muab rau qhov ntsuas qhov xav tau thiab ib puag ncig, thiab cov kev xav tau ntawm kev txhim kho thiab kev saib xyuas yuav tsum tau ua raws li kev ntsuas thiab kev pabcuam lub neej ntawm thermocouples.
