Kev sojntsuam, xaim thiab infrared yog ntau hom thermocouples. Feem ntau ntawm cov no siv cov hlau hauv paus rau cov xov hlau thiab tau sau nrog tsab ntawv uas sib haum nrog hom hlau. Cov ntawv no yog hu ua calibrations. Feem ntau hom yog J, K, T, E thiab N. Hom K thermocouples, uas siv cov nickel alloys, yog nrov tshaj plaws. Lawv yog cov ruaj khov heev thiab muaj qhov dav ntawm qhov kub thiab txias. Qee hom, suav nrog hom J, uas siv hlau, muaj zog sib nqus thiab tsim nyog rau kev siv tsawg.
Ntau hom thermocouples muaj nyob, thiab txhua qhov ua tau raws li qhov xav tau hauv cov ntawv thov tshwj xeeb raws li qhov kub thiab txias. Vim li no, lub ntsuas hluav taws xob kuj txiav txim siab hom thermocouple. Cov ntaub ntawv nyias nyias tsis tuaj yeem tuav kom kub siab dua yam tsis muaj kev puas tsuaj.
Cov thermocouples siab dua siv cov hlau zoo rau cov xov hlau tab sis tsis tshua muaj. Cov no yog hom R, S, C thiab GB thermocouples.
Txhawm rau xaiv qhov zoo thermocouple rau koj xav tau:
Saib ntawm qhov ntsuas kub, ntsuas qhov ntsuas thiab qhov tseeb.
Kev siv kub heev, zoo li metallurgy, yuav xav tau hom K thermocouples. Cov tshuab tso pa tawm yuav ua haujlwm zoo nrog hom T thermocouples.
Nco ntsoov qhov raug raws li koj daim ntawv thov xav tau. Kev ua yuam kev tsawg dua 1 degree yog qhov nyuaj thiab kim kom ua tiav, tshwj xeeb tshaj yog nyob rau qhov kub siab tshaj.
Xav txog kab ntsuas. Thicker xov hlau yuav zam qhov kub thiab txias ntev dua.
