Sib tham txog cov txheej txheem sib txawv ntawm kev lag luam thermoco

Muaj kev sib sau ua ke thermoco yog sensors rau kev ntsuas kub, uas txuas nrog los ntawm ob qho sib txawv hlau tus cwj pwm. Thaum ntsuas kub ntawm ob tug neeg uas sib txawv ntawm qhov sib txuas txuas, hluav taws xob muaj peev xwm tsim tawm, yog li qhov ntsuas kub ntawm qhov ntawd tuaj yeem suav. Vim nws cov qauv kev cog lus thiab kev teeb tsa yooj yim, sib sau ua ke thermocouples tau siv dav hauv kev lag luam tsim, thermal zog, petrochemical thiab tshuaj lom neeg.
Tus qauv ntawm kev sib sau ua ke thermocouples tsuas yog suav nrog peb ntu: kev tiv thaiv raj, thermocouple caij thiab lub taub hau dav hlau. Lub raj tiv thaiv feem ntau yog ua los ntawm cov hlau tsis xeb, tungsten steel thiab lwm yam ntaub ntawv, uas tuaj yeem tiv thaiv cov khoom siv thermocouple los ntawm tus ntawm sab nraud ib puag ncig. Lub caij thermocouple yog tsim ntawm ob tus neeg sib txawv hlau sib txuas, feem ntau ua los ntawm tooj liab, hlau, npib tsib xee thiab muaj kev nkag siab zoo thiab ruaj khov. Lub taub hau davhlau ya nyob twg yog siv los txuas cov thermocouple rau seev cev thiab lwm yam khoom siv, feem ntau ua los ntawm cov khoom noj qab zib ceramic, nrog rwb thaiv tsev zoo thiab kub tsis kam.
Muaj ntau txoj kev teeb tsa rau kev lag luam thermocouples, uas tuaj yeem raug xaiv raws li cov kev xav tau tiag tiag. Cov uas muaj cov ntsiab lus sib txuas, hom sib luag thiab cov hom ntab. Ntxig thermocouples feem ntau yog nruab rau hauv cov kav dej lossis ntim khoom, thiab tuaj yeem soj ntsuam cov kev hloov pauv hloov tshiab hauv lub sijhawm thiab tswj cov txheej txheem ntau lawm. Taag thermocouples yog ntsia hauv cov haujlwm tas thiab feem ntau yog siv los ntsuas qhov kub thiab txias lossis khoom siv qhov chaw kub. Floating thermocouples tuaj yeem txav thiab hloov raws li xav tau, thiab haum rau qee lub sijhawm tshwj xeeb.

Ua ke thermocouples muaj qhov ntsuas siab, cov lus teb ceev nrawm thiab muaj kev ntseeg siab. Tshwj xeeb tshaj yog nyob rau hauv qee qhov chaw hnyav uas muaj kev kub ntxhov thiab yooj yim thiab yooj yim thermocouples tuaj yeem tswj tau ruaj khov ua tau zoo thiab muaj qhov tseeb siv sijhawm ntev. Txawm li cas los xij, sib sau ua ke thermocouces kuj muaj qee qhov tsis zoo, xws li muaj kev pom zoo tsawg, uas yuav tsum tau them nyiaj rau hauv kev siv tiag tiag.

Raws li qhov tseem ceeb ntsuas kub, kev sib sau ua ke thermocouples muaj kev sib tw thov kev cia siab hauv kev lag luam tsim, chemistry, lub zog thiab lwm thaj teb. Nrog kev txhim kho txuas ntxiv thiab tsim kho tshiab ntawm thev naus laus zis, nws ntseeg tau tias cov kev sib sau ua ke thermocouples thiab zoo meej, muab cov kev txhawb nqa zoo dua, kev nyab xeeb thiab kev nyab xeeb ntawm kev lag luam tsim khoom.
