Qhov zoo thiab cov ntsiab cai ntawm Armored Thermocouples
Nws muaj ntau yam zoo xws li khoov muaj peev xwm, kev kub siab ua haujlwm, lub sij hawm thermal teb sai, thiab kav ntev. Zoo li kev lag luam sib sau ua ke thermocouples, nws ua haujlwm rau kev ntsuas kub thiab feem ntau yog siv ua ke nrog cov cuab yeej tso saib, kaw cov twj paj nruag, thiab cov tswj hluav taws xob. Nws tseem tuaj yeem ua qhov ntsuas qhov ntsuas kub rau cov thermocouples sib dhos. Nws tuaj yeem ntsuas qhov ntsuas kub ntawm cov kua, chav, thiab cov pa tawm, nrog rau qhov chaw ntawm cov khib nyiab, nyob rau thaj tsam ntawm 0 ~ 800 degree thaum lub sijhawm tsim khoom.
txoj cai
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm armored thermocouples yog tias ob qhov sib txawv ntawm cov neeg xyuas pib tau welded ntawm ob qho kawg los ua ib lub voj voog. Qhov ntsuas kub ncaj qha qhov kawg yog hu ua qhov kawg ua haujlwm, thiab qhov kawg ntawm lub davhlau ya nyob twg yog hu ua txias kawg, tseem hu ua qhov kawg siv. Thaum muaj qhov sib txawv ntawm qhov kub thiab txias ntawm qhov kev ua haujlwm kawg thiab qhov kawg siv, thermal tam sim no yuav raug tsim tawm hauv Circuit Court. Thaum txuas nrog lub ntsuas ntsuas, qhov ntsuas yuav qhia qhov ntsuas kub ntawm qhov ntsuas kub ntawm lub tshuab hluav taws xob hluav taws xob uas tsim los ntawm thermocouple.
Lub thermoelectric electromotive quab yuam ntawm armored thermocouples yuav nce raws li qhov kub ntawm qhov ntsuas qhov kawg nce. Qhov loj ntawm cov thermoelectric electromotive quab yuam tsuas yog cuam tshuam nrog cov khoom ntawm cov khoom siv thermocouple thiab qhov kub thiab txias sib txawv ntawm ob qhov kawg, thiab tsis cuam tshuam rau qhov ntev thiab txoj kab uas hla ntawm cov thermoelectric electrode.
Lub hauv paus ntsiab lus ntawm armored thermocouple yog tias nws yog ua los ntawm ib tug neeg xyuas pib, siab rwb thaiv tsev magnesium oxide, thiab 1Cr18Ni9Ti stainless hlau tiv thaiv raj, uas yog rub ntau zaus hauv ib qho. Armored thermocouple cov khoom lag luam feem ntau muaj cov qauv yooj yim uas muaj lub thawv sib txuas, cov khoom siv davhlau ya nyob twg, thiab cov thermocouples armored, thiab tau nruab nrog ntau yam kev teeb tsa thiab kho cov cuab yeej.
Armored thermocouples muab faib ua ob hom: rwb thaiv tsev hom thiab plhaub hom.

Thermal teb lub sij hawm ntawm armored thermocouple
Thaum muaj cov kauj ruam hloov ntawm qhov kub thiab txias, lub sij hawm thaum cov zis ntawm lub thermocouple hloov mus rau 50% ntawm cov kauj ruam hloov yog hu ua thermal teb lub sij hawm τ 0.5 sawv cev.
