Kev ntsuas thiab ntsuas kub ntsuas ntau ntawm cov thermoco

Tam sim no kev ua haujlwm tam sim no pom zoo los ntawm International Electrotechnical Commission yog raws li hauv qab no:

1. Platinum rhodium 10 Platinum thermocouple (s-hom thermocouple). Haum rau kev ntsuas kub hauv oxidizing huab cua, tsis pom zoo nyob rau hauv kev txo cov huab cua, siv luv luv hauv ib puag ncig. Lub sijhawm ntev siv ntsuas kub yog 0-1300 degree, thiab lub sijhawm luv luv siv yog {}} degree.

2. Platinum Rhodium 13 Platinum Thermocouple (R-Hom). Siv tau rau S-Typ thermocouples hauv lub tshav pob.

3. Platinum rhodium 3 {0 platinum rhodium 6 thermocouple (ntaus b). Haum rau kev ntsuas kub hauv oxidizing huab cua, nws lub ntsiab tseem ceeb yog qhov muaj zog ruaj khov, thiab tsis muaj cov hlau rho nyiaj xav tau thaum siv ntsuas kub 0 ~ 100 degree. Lub sijhawm ntev siv ntsuas kub yog 0-1600 degree, thiab lub sij hawm luv luv kub yog {8}} degree.

4. Nickel chromium tsibckel silicon thermocouple (k-hom). Haum rau kev ntsuas kub hauv oxidizing huab cua, tsis pom zoo rau kev siv hauv kev txo cov cua. Qhov ntsuas kub tau txiav txim siab los ntawm txoj kab uas hla ntawm thermocouple, feem ntau} {2}

5. Nickel Chromium Silicon npib tsib xee silicon thickocouple (n-hom). Qhov ntsuas kub ntsuas yog 0-1300 degree, nrog kev ruaj khov zoo.

6. Nickel Chromium Constantan Thermocouple (ntaus e). Haum rau kev ntsuas kub hauv oxidizing thiab qaug zog txo cov cua, nrog ib qho kub ntawm {1}} ~ 900 degree.

7. Hlau Constantan Thermocouple (J-hom). Haum rau kev ntsuas kub hauv oxidizing thiab txo cov cua thiab hauv lub tshuab nqus tsev, nrog kub ntau ntawm {2}} ~ 750 degree.

8. Coppet constantan thermocouple (t-hom). Haum rau kev ntsuas kub nyob rau hauv thaj tsam ntawm -200 2} Nws muaj tseeb, nws lub siab ruaj khov, thiab tus nqi qis.

Ntxiv nrog rau lub thoob ntiaj teb cov qauv hais los ntawm cov hluav taws xob cuam tshuam saum toj no, tseem muaj qauv ntsuas thermocouples haum rau qee qhov tshwj xeeb ntsuas thiab cov xwm txheej:

1. Tungsten rhenium 3-} Tungsten Rhenium 25 Thermocouple (WRE3 / 25 hom). Raws li Asmeskas Astmee {5}} thermocouple yog haum rau hauv cov roj, thiab lub tshuab nqus tsev, nrog qhov ntsuas kub ntawm {{6 degree.

2. Tungsten Rhenium 5-} Tungsten Rhenium 26 thermocouple (wre5 / 26 hom). Haum rau kev ntsuas kub hauv cov roj inert thiab hydrogen, thiab tseem siv tau rau hauv cov chaw nqus tsev, nrog kub ntau ntawm {5}} degree.

3. Nickel Chromium Kub Hlau Hlau Thermocohople. Haum rau kua nitrogen thiab kua hydrogen media nyob rau hauv qhov tsawg tsawg ntawm {} k.

4. Tsis yog xim hlau thermocouple. Nws muaj cov yam ntxwv ntawm cov peev xwm siab thermoelectric muaj peev xwm thiab siab melting point. Graphite Titanium carbide thermocouple tuaj yeem ntsuas qhov kub siab txog 2000 degree hauv carbon muaj thiab nruab nrab cua; Boron carboid graphite thermocouplets nyuaj, hnav-resistant, siab tiv taus kub, thiab tawm tsam oxidation. Nws muaj zoo linarity thiab siab thermoelectric muaj peev xwm nyob rau hauv ntau ntawm {{}} degree. Txawm li cas los xij, tsis yog hlau tawv thermocots muaj kev tsis zoo reprucibility thiab qis dua kev siv zog.
