Yuav ua li cas xam qhov kub ntawm lub thermocouple nrog tus nqi k-score

1. Thermocouples
Thermocouples, tseem hu ua thermoelectric khub, yog cov sensors nquag siv los ntsuas qhov kub thiab txias. Nws muaj cov ntsiab lus vuam ntawm ob txoj hlua hlau sib txawv (feem ntau yog tooj liab thiab hlau lossis phom thiab npib tsib xee). Xam qhov kub hloov pauv los ntawm kev ntsuas qhov sib txawv ntawm qhov sib txawv ntawm cov ntsiab lus vuam.
2. K-point thermocouple
Cov qhab-nees k yog ib qho tseem ceeb ntawm cov thermocouple, uas yog hais txog qhov hluav taws xob tsim los ntawm qhov ntsuas kub ntawm ib chav tsev kub qhov sib txawv. Cov hom thermocouples feem ntau siv xws li K, J, T, thiab lwm yam, thiab cov qhab-nees k yog qhov tshwj xeeb rau txhua hom thermocouple.
3. xam qhov kub thiab txias
Txhawm rau xam qhov ntsuas kub uas siv lub thermocouple nrog tus nqi k-score, ob qhov tseem ceeb yuav tsum paub: qhov sib txawv (ie voltage) tsim los ntawm cov thermocouple thiab tus nqi k-score. Los ntawm kev ntsuas qhov muaj peev xwm sib txawv thiab tom qab ntawd xam raws li k-score, qhov ntsuas kub tuaj yeem tau txais.
Cov mis tshwj xeeb rau kev ntsuas kub yog raws li hauv qab no:
Kub (degree)=Qhov sib txawv (mV)/k-score (mV/degree)
Ua ntej, siv cov cuab yeej ntsuas tsim nyog los ntsuas qhov sib txawv uas tsim los ntawm cov thermocouple. Chav tsev ntawm qhov sib txawv feem ntau yog millivolts (mV).
Tom qab ntawd, thaum xam qhov ntsuas kub, nws yog ib qho tsim nyog yuav tsum tau tshawb nrhiav qhov sib npaug k-score tus nqi raws li hom thermocouple siv. Qhov ntsuas kub tuaj yeem muab tau los ntawm kev faib cov peev txheej sib txawv los ntawm k qhab nia.
Nws yuav tsum raug sau tseg tias kev ntsuas qhov sib txawv ntawm qhov sib txawv thiab siv qhov tseeb k-score tus nqi yog qhov tseem ceeb los xyuas kom meej qhov ntsuas kub kom raug. Tsis tas li ntawd, thaum ua kev suav, nws yuav tsum tau them sai sai rau qhov sib xws ntawm cov ntsuas kub, xws li hloov lub zog ntawm qhov sib txawv rau millivolts thiab faib los ntawm k cov ntsiab lus.
4. Daim ntawv thov teb
K-point thermocouples yog siv dav hauv kev lag luam. Vim nws qhov ntsuas kub dav dav, qhov kub thiab txias, cov lus teb ceev ceev, thiab kub tsis kam, thermocouples yog siv rau ntau yam ntawm kev ntsuas kub thiab tswj cov tshuab.
Cov chaw thov kev lag luam muaj xws li kev lag luam petrochemical, kev lag luam metallurgical, lub zog hluav taws xob, kev ua zaub mov, thiab lwm yam. Hauv cov teb no, cov thermocouples tuaj yeem siv los saib xyuas thiab tswj qhov kub ntawm cov txheej txheem tsim khoom kom ntseeg tau tias cov khoom zoo thiab kev ua haujlwm zoo.
Tsis tas li ntawd, cov thermocouples feem ntau yog siv nyob rau hauv cov chaw soj nstuam thiab cov khoom siv kho mob los ntsuas qhov kub thiab txias hauv qhov kub thiab txias.
Hauv cov ntsiab lus, k-point thermocouples yog ib qho kev ntsuas kub uas feem ntau siv, thiab thaum xam qhov ntsuas kub, nws yog ib qho tsim nyog los ntsuas qhov sib txawv ntawm qhov sib txawv thiab siv tus nqi sib thooj k-point. Nws muaj ntau yam kev siv hauv kev lag luam thiab kev tshawb fawb, muab cov kev daws teeb meem txhim khu kev qha thiab raug rau kev ntsuas kub thiab tswj.
