Dab tsi yog qhov ntsuas kub rau Screw-hauv Thermocouples thiab Lawv Ua Li Cas?

Lawv muab qhov ntsuas kub kom raug. Hauv cov txheej txheem kev lag luam uas tshwj xeeb tswj qhov kub thiab txias yog qhov tseem ceeb, ntsia hlau-hauv thermocouples tuaj yeem muab cov ntaub ntawv muaj kev vam meej. Lawv kuj tseem kav ntev thiab tuaj yeem tiv taus qhov chaw hnyav. Txawm hais tias tsis muaj qhov kub thiab txias ntau dhau, cov khoom corrosive, lossis kev ntxhov siab, cov thermocouples yog tsim los ua kom lawv cov haujlwm ua haujlwm. Tsis tas li ntawd, lawv qhov yooj yim ntawm kev teeb tsa yog qhov txiaj ntsig zoo. Cov ntsia hlau-nyob rau hauv layout cia nyob rau hauv luv luv thiab khov kho qhov chaw nyob rau hauv qhov chaw dimension.
Daim ntawv ntawm cov ntsia hlau-hauv thermocouples ua lub luag haujlwm tseem ceeb. Threaded Cheebtsam tso cai rau kev teeb tsa. Nws tuaj yeem raug ntsia tau tam sim ntawd rau hauv txoj hauv kev los yog cov yeeb nkab, ua kom muaj kev sib haum xeeb thiab txo txoj hauv kev ntawm kev txav los yog kev tsis sib haum xeeb. Qhov sib npaug no yog qhov tseem ceeb rau qhov tseeb qhov ntsuas kub, vim tias txhua qhov kev txav tuaj yeem ua rau kev nyeem tsis raug. Daim ntawv no tseem tso cai rau kev tshem tawm kom huv thiab lwm txoj hauv kev thaum tsim nyog, tsis muaj kev cuam tshuam loj heev rau txoj kev.
Screw-in thermocouples muaj qhov txwv kub tshwj xeeb. Qhov kub ntau yam yog nyob ntawm daim ntawv ntawm thermocouple thiab nws cov kev tsim kho. Piv txwv li, ob peb lub ntsia hlau-hauv thermocouples tuaj yeem ntsuas kub ntawm -200 degree mus rau 1300 degree . Thaum txo qhov kub thiab txias, lawv tuaj yeem tsim nyog los ntawm qhov chaw tsis muaj ntshav, txawm tias qhov kub zoo dua, lawv muaj peev xwm tiv taus qhov sov so ntau dhau.
Hauv kev ua haujlwm, ntsia hlau-hauv thermocouples nqa tawm los ntawm txoj kev los ntawm kev tsim hluav taws xob voltage proportional rau qhov kub thiab txias ntawm qhov ntsuas qhov sib txuas thiab cov kev siv sib txuas. Qhov voltage no ces ntsuas thiab hloov txoj cai mus rau qhov ntsuas kub. Qhov tseeb ntawm qhov loj me yog nyob ntawm ntau yam, suav nrog kev nplua ntawm cov khoom siv, kev ntsuas ntawm cov thermocouple, thiab cov xwm txheej ib puag ncig.
Hauv cov ntawv thov kub ntau dhau, cov ntsia hlau-hauv cov thermocouples feem ntau yog tsim los ntawm cov khoom uas tuaj yeem tiv taus qhov sov so ntau dhau nrog qhov tsis zoo. Piv txwv li, ob peb lub thermocouples siv tshwj xeeb alloys los yog ceramics uas yuav tswj tau qhov kub thiab txias ntau npaum li ntau txhiab degrees Celsius. Hauv cov ntawv thov kub qis, cov thermocouples tuaj yeem tsim nrog cov khoom uas muaj cov thermal conductivity ntawm qhov kub tsawg.
