Ua ntej, nyob rau hauv cov nqe lus ntawm cov khoom muaj pes tsawg leeg, J - hom thermocouple hlau muaj ib tug hlau - constantan ua ke. Cov hlau ua raws li cov ceg zoo, thaum lub constantan (atooj liab - npib tsib xee alloy) ua hauj lwm raws li qhov tsis zoo ceg. Hauv qhov sib piv, K - hom thermocouple hlau yog ua los ntawm achromel- kev sib xyaw alumel. Chromel, uas yog tsim los ntawm npib tsib xee thiab chromium, yog cov ceg zoo, thiab alumel, nickel - aluminium - manganese - silicon alloy, yog cov ceg tsis zoo. Qhov sib txawv ntawm cov khoom no ua rau muaj kev hloov pauv hauv lawv cov yam ntxwv ua haujlwm.

Qhov thib ob, qhov ntsuas kub ntawm lawv tuaj yeem ntsuas qhov sib txawv.J - hom thermocouplesFeem ntau tuaj yeem ntsuas qhov kub ntawm -210 ° C txog 760 ° C. Lawv yog cov zoo - haum rau ntau yam kev siv nrog rau qhov kub thiab txias. Piv txwv li, hauv kev lag luam ua zaub mov, J - hom thermocouples feem ntau yog siv rau hauv qhov cub ci. Thaum ci qhob cij, qhov kub hauv qhov cub feem ntau yog li ntawm 150 ° C txog 250 ° C. Peb cov khoom zoo J-hom thermocouple xov hlau tuaj yeem saib xyuas qhov kub thiab txias, kom ntseeg tau tias lub khob cij ci sib npaug thiab ua tiav qhov zoo nkauj zoo nkauj. Lwm daim ntawv thov yog nyob rau hauv kev tsim tshuaj, qhov twg J - hom thermocouples yog siv los ntsuas qhov kub thiab txias thaum lub sij hawm ziab ntawm qee yam tshuaj. Qhov kub ntawm cov txheej txheem no feem ntau khaws cia li ntawm 50 ° C txog 70 ° C, thiab peb cov khoom siv J-hom thermocouple xaim tuaj yeem muab cov ntaub ntawv ntsuas kub zoo, tiv thaiv cov tshuaj zoo.

K - hom thermocouples, ntawm qhov tod tes, muaj qhov dav dua qhov kub ntawm - 200 ° C txog 1350 ° C. Qhov no ua rau lawv indispensable nyob rau hauv high-temperature daim ntaub ntawv. Hauv kev lag luam steel,K-hom thermocouplesyog siv los saib xyuas qhov kub thiab txias hauv qhov cub tawg. Qhov kub ntawm qhov cub tawg tuaj yeem ncav cuag 1200 ° C lossis siab dua. Peb cov K-hom thermocouple xov hlau tuaj yeem tiv taus cov cua sov thaum tswj xyuas qhov tseeb, tso cai rau cov neeg ua haujlwm kom tswj tau cov txheej txheem smelting thiab xyuas kom zoo ntawm cov hlau. Nyob rau hauv lub tshav dav hlau aerospace, thaum lub sij hawm kev ntsuam xyuas ntawm lub dav hlau engine Cheebtsam, K - hom thermocouples yog siv los ntsuas qhov kub - kub gases generated thaum lub sij hawm lub engine. Cov pa roj no tuaj yeem ncav cuag qhov kub thiab txias ze li 1300 ° C, thiab peb cov khoom siv K-hom thermocouple hlau tuaj yeem muab qhov ntsuas kub kom raug, uas yog qhov tseem ceeb rau kev txhim kho thiab kev ua kom zoo ntawm cov tshuab dav hlau.

Qhov tseeb yog lwm qhov tseem ceeb. K - hom thermocouples feem ntau muab qhov tseeb zoo dua li qhov kub ntau yam piv rau J - hom thermocouples. Kev ruaj ntseg ntawm K - hom thermocouples nyob rau hauv ib puag ncig hnyav kuj tseem ua rau lawv cov precision siab dua, ua rau lawv xaiv rau kev tshawb fawb thiab kev ua haujlwm siab.

Ntawm Tankii, peb cov khoom J thiab K thermocouple hlau yog tsim los nrog kev tswj xyuas nruj. Peb cov J-hom thermocouple xov hlau ua kom ntseeg tau tias kev ua tau zoo nyob rau hauv lawv qhov kub thiab txias, thaum peb K-hom thermocouple xov hlau yog tsim los tiv thaiv qhov kub thiab txias nrog qhov tseeb thiab ruaj khov. Txawm hais tias koj yuav tsum ntsuas cov txheej txheem ntawm lub tub yees qis lossis qhov kub thiab txias, peb cov khoom siv thermocouple xaim tuaj yeem muab cov ntaub ntawv ntsuas kub zoo thiab ruaj khov rau koj, pab koj txhim kho koj cov haujlwm thiab ua kom cov khoom zoo.
