Thaum siv thermocouple them nyiaj, thov them sai sai rau tus naj npawb ntawm cov nias uas phim tus qauv: 199 {}}: 26:39
Ob yam khoom sib txawv ntawm cov neeg coj ua txawv lossis welded semiconductors a thiab b sau ib qho kev kaw Circuit Court. Thaum muaj qhov sib txawv kub ntawm ob qho ntsiab lus txuas 1 thiab 2 ntawm kev ua haujlwm thiab b, thiab tam sim no yog tsim nyob rau hauv Circuit Court, thiab muaj qhov loj tam sim no yog tsim nyob rau hauv Circuit Court, uas yog hu ua cov nyhuv thermoelectric nyhuv. Thermocoples siv cov nyhuv no ua haujlwm.
Feem ntau siv thermocouples feem ntau muab faib ua ob pawg: qauv thermocoorples thiab cov thermoco zog. Tus txheem thermocouple siv yog hais txog thermocouple uas tau teev nyob rau hauv lub teb chaws tus qauv rau kev sib raug zoo ntawm thermoelectric muaj peev xwm thiab kub, thiab muaj kev sib koom ua ke ntsuas, thiab muaj cov khoom sib txuam. Tsis yog qauv thermocoen tsis haum rau siv li thermoounles nrog cov qauv sib txawv lossis cov xaj ntawm qhov ntau, thiab feem ntau tsis muaj kev sib koom ua ke. Lawv feem ntau yog siv rau kev ntsuas hauv cov xwm txheej tshwj xeeb.
Cov khoom siv ntawm thermocouples feem ntau muaj nuj nqis (tshwj xeeb yog thaum siv cov hlau uas muaj zog), thiab qhov kev ncua deb ntawm qhov ntsuas kub ntsuas rau lub ntsuas kom deb. Txhawm rau kom txuag tau cov khoom ntawm thermocouples thiab txo cov nqi, cov xaim them nyiaj yog siv los txuas qhov ntsuas cua sov (txias) Nws yuav tsum tau taw qhia tias kev them hluav taws xob thermocouple rau ntawm chav ntsuas kub ntawm lub davhlau ya nyob twg ntawm kev ntsuas txias nyob rau hauv qhov ntsuas txias rau thaum ntsuas kub, thiab tsis tuaj yeem them nyiaj. Therefore, in order to compensate for the cooling temperature t{{0}}&ne, other correction methods are needed to affect the temperature measurement at 0 degree .
Thaum siv Thermocouple them nyiaj, nws yog ib qho tseem ceeb kom paub meej nyob rau hauv daim ntawv thiab tsis txhob muaj kev yuam kev polarity. Qhov ntsuas kub ntawm kev sib txuas xaus ntawm cov xaim hluav taws xob thiab thermocouple yuav tsum tsis tshaj 100 degree.
Thermal kuj yog ib qho siv tau siv tau kub nyob rau hauv nruab nrab thiab qhov kub tsawg. Nws cov cwj pwm tseem ceeb yog qhov ntsuas siab yog qhov tseeb thiab ruaj khov ua haujlwm. Ntawm lawv, platinum muaj qhov siab tshaj tawm kev ntsuas thiab tau siv dav tsis yog nyob rau hauv kev lag luam kub ntsuas, tab sis kuj nyob rau hauv cov kev ntsuas cov twj.
