Dab tsi yog qhov ntsuas kub ntsuas ntsuas los ntawm thermocouples thiab cov cua nab?

Thermocouples ntsuas ntsuas kub hauv thaj tsam ntawm 0}}}}} paksistors ntsuas kub hauv thaj tsam ntawm {2}} ~ 500 degree.
1. Thermocouple yog ib qho ntsuas kub uas siv ntsuas ntsuas ntsuas ntsuas hauv cov twj paj nruag ntsuas. Nws ntsuas ncaj qha kub thiab hloov cov teeb liab kub rau hauv qhov kub thiab txias ntawm cov twj ntsuas hluav taws xob (theem nrab seev). Cov tsos ntawm ntau thermocouples feem ntau sib txawv heev vim lawv cov kev xav tau, tab sis lawv cov qauv yooj yim yog ntxig tib yam. Lawv feem ntau yog tsim cov khoom loj xws li cov ntaub ntawv kub, thiab feem ntau yog siv rau cov twj paj nruag, kaw cov twj paj nruag, thiab cov neeg siv hluav taws xob, thiab cov neeg siv hluav taws xob.
2. Thermal resistor yog ib qho kev siv ntsuas kub feem ntau hauv nruab nrab thiab kub kub ntau. Thermal kuj ntsuas kub yog raws li tus yam ntxwv uas cov nqi tiv thaiv ntawm cov hlau uas nce nrog ntsuas kub. Nws cov yam ntxwv tseem ceeb yog qhov ntsuas siab yog qhov tseeb thiab ruaj khov ua haujlwm. Kev ntsuas ntawm cov pas ntsuas kub yog * *, uas tsis yog siv dav hauv kev lag luam kub, tab sis kuj tau ua rau hauv ib qho kev ntsuas kub. Feem ntau cov cua sov yog tsim los ntawm cov ntaub ntawv hlau ntshiab, nrog platinum thiab tooj liab yog feem ntau siv. Ntxiv rau, cov ntaub ntawv xws li npib tsib xee, manganese, thiab rhodium tau siv los ua cov thermistors. Muaj ntau ntau hom kev hnov ​​ntsuas kub feem ntau siv nyob rau hauv cov thermistors, nrog platinum xaim yog cov nquag siv. Ntxiv rau cov platinum xaim, kuj tseem tooj liab, npib tsib xee, hlau, hlau npib kub thiab lwm yam khoom siv hlau tshuab thickistor siv.

Thermoelectrric resistors tuaj yeem faib ua ntau yam sib txawv. Cov nquag siv nyob rau hauv kev ua lag luam tam sim no yog platinum cov cua nab, uas tuaj yeem muab faib ntxiv rau hauv mica, ceramic, thiab nyias zaj duab xis. Qhov ntsuas kub ntau ntau kuj txawv, xws li -200 rau 600 degrees.
Thermocouples can also be divided into various calibration numbers, such as S platinum rhodium alloy (rhodium content 10%), pure platinum 0-1400 R platinum rhodium alloy (rhodium content 13%), pure platinum 0-1400 B platinum rhodium alloy (rhodium content 30%), platinum rhodium alloy (rhodium content 6%), 0-1400 kibel chromium tsib xee tooj liab tooj liab no {}} nickel {} {} {tungsten rhenium 0-+2400
Qhov kub thiab txias yog 0-2400 degrees.
Thaum xaiv qhov ntsuas kub thiab txias, ib lub ntsiab cai yog siv cov hom uas tsim nyog ntawm sensor rau qhov kub. Tsuas yog xaiv lub ntsuas kom haum rau qhov yog qhov raug ua tiav, xws li -50-100 degrees Celsius. Hauv kev sib piv, qhov tseeb ntawm cov cua nab hluav taws xob siab dua li ntawm qhov thermocouple. Tsuas yog thaum qhov ntsuas kub siab dua qhov ntsuas kub thiab txias ntawm cov cua nab dej, xws li 0-700 degrees Celsius, peb tuaj yeem xaiv E-hom Thermocouple.
