Kev nyab xeeb & ntseeg tau: tawg-Cov pov thawj Thermocouple rau ib puag ncig txaus ntshai
Cov khoom no yog ib qho tshwj xeeb kub sensor engineered los ua hauj lwm yam xyuam xim nyob rau hauv flammable, explosive, los yog corrosive ib puag ncig, combining raug ntsuas kub nrog robust robust{0}} pov thawj tiv thaiv. Tsim los nrog kev ua raws li GB 3836 cov qauv nruj, cov khoom tiv thaiv cov nplaim taws lossis kub kub los ntawm kev kub hnyiab cov khoom phom sij, ua rau nws tseem ceeb rau siab - kev pheej hmoo ntawm kev lag luam. Txawm hais tias nyob rau hauv cov nroj tsuag tshuaj, roj refineries, lossis cov mines thee, cov khoom lag luam xa cov ntawv nyeem zoo ib yam, txhim khu kev qha thaum ua kom muaj kev nyab xeeb ntawm kev ua haujlwm- hais txog qhov xav tau tseem ceeb rau kev txo qis hauv kev ua haujlwm hnyav.
Cov khoom tsim tshwj xeeb rau ntau hom kev phom sij
Tsev neeg cov khoom raug cais los ntawm kev tawg- hom pov thawj, qhov kub thiab txias, thiab daim ntawv thov kom haum rau qhov chaw muaj kev phom sij tshwj xeeb. Hauv qab no yog ib daim ntawv qhia kev xaiv tswv yim:

Cov Khoom Siv Tshwj Xeeb & Ntawv pov thawj qib ntawm tawg-Cov pov thawj Thermocouple
Txhua yam khoom yog tsim los nrog cov khoom zoo - cov khoom zoo los tiv thaiv cov xwm txheej hnyav. Nws cov thermoelectrodes suav nrog K- hom (NiCr-NiSi) rau qhov nruab nrab nruab nrab- siab kub, S- hom (PtRh10-}Pt) rau siab - qhov kub thiab txias, thiab B- hom (PtRh30} . siab tshaj 13. Kev tawg-cov ntaub ntawv pov thawj lub thawv siv cov cam khwb cia txhuas (tus nqi- siv tau rau thaj chaw uas tsis muaj corrosive) lossis 304/316 stainless hlau (corrosion-resistant rau chemical ib puag ncig), thaum cov raj tiv thaiv txawv ntawm 304/316 stainless hlau (kev siv dav dav) mus rau Hastelloy (corrosive 0℃saum toj no 10).
Ua raws li lub teb chaws tus qauv, cov khoom muaj Class Ⅰ thiab Ⅱ raug, nrog tawg - cov qhab nia pov thawj kom meej meej (xws li, Ex d ⅡC T4 Gb).
