Yuav ua li cas txuas tau cov kev pabcuam lub neej ntawm thermocouples

Hauv kev xyaum, sib sau ua ke thermocouples feem ntau muaj cov leeg tiv thaiv, thiab hauv cov xwm txheej tshwj xeeb tsuas yog siv. Yog li ntawd, feem ntau, lub neej ntawm lub raj tiv thaiv tiv thaiv tau tuaj yeem txiav txim lub neej ntawm thermocouple. Txhawm rau txiav txim siab lub neej tiag tiag ntawm thermocouple, nws yog ib qho tsim nyog los sau thiab khaws cov ntaub ntawv rau lub sijhawm ntev hauv kev thov kom muab cov txiaj ntsig zoo.

Thermocoter yog qhov tseem ceeb thiab feem ntau siv cov kev tswj hwm qhov kub thiab txias thiab siv tau kub Txawm hais tias tus qauv yooj yim, yog tias tsis ceev faj, tseem muaj peev xwm tseem ceeb ntsuas yuam kev. Ntawm no, teb rau cov teeb meem yooj yim hauv cov ntawv thov, cov ntsiab lus ntxaws ntxaws ntawm kev xaiv qhov tob ntawm thermociation, thermal hluav taws xob, thiab thermal impedance. Qhov tsis muaj kev sib txawv ntawm thermocoples, daim ntawv thov ib puag ncig, thiab rwb thaiv tsev tsis kam tau taw qhia los ntawm cov ntaub ntawv sau ua yuam kev.

Qhov thiaj li hu ua thermocouple degradation yog hais txog kev laus thiab kev cuam tshuam ntawm thermocouces tom qab siv. Thermocouples ua los ntawm cov hlau lossis alloy loj hlob ntawm qhov kub. Alloy cov ntaub ntawv muaj ib qho kev cuam tshuam me me ua ke, uas tuaj yeem ua rau kev hloov pauv lossis cov qauv zoo uas muaj cov roj ntsha oxidizing hauv peb ib puag ncig nyob ib puag ncig.

Nrog cov kev hloov pauv no, lub peev xwm thermoelectric ntawm Thermocouple yuav tseem tau rhiab. Yog li ntawd, qhov kev cuam tshuam ntawm thermocouples yog unavoidable. Qhov kev cuam tshuam ntawm thermocouples yog qhov nyuaj kom muaj nuj nqis kom muaj nuj nqis ntau. Nws yuav cuam tshuam rau ntau yam, txoj kab uas hla, siv ib puag ncig kub, huab cua, thiab lub sijhawm ntawm cov khoom cuav thermocouple. Qhov kev pabcuam lub neej ntawm qhov thermocouple yog txhais raws li lub sijhawm thaum lub sijhawm poob ntawm thermocouple ntau tshaj qhov tsis muaj kev ua yuam kev lossis thermocouple tsis tuaj yeem siv vim kev txiav txim siab.
