Hauv kev sib tham dhau los, kuv tau hais txog 3 lub ntsiab lus ntawm cov lus nug uas nquag nug txog thermocouple thiab RTD ntsuas kub. Hnub no, kuv yuav txuas ntxiv nrog 2 cov ntsiab lus ntxiv.
IV. Dab tsi yog Mineral Insulated Thermocouple, thiab nws qhov zoo yog dab tsi?
Raws li IEC 1515 tus qauv, nws txhais tau tias yog Mineral Insulated Thermocouple Cable. Nws sab nrauv zoo li yuav tsum tau them nrog ib txheej ntawm "cov cuab yeej cuab tam", yog li lub npe ntxhia insulated thermocouple.
Piv nrog cov pa sib dhos thermocouples, nws muaj cov yam ntxwv siab dua, khoov tau zoo, zoo oxidation tsis kam thiab ua haujlwm ntev.
V. Cov thermocouple sib txawv yog dab tsi, thiab lawv cov yam ntxwv yog dab tsi?
Cov thermocouple ntau hom muaj xws li S, R, B, N, K, E, J, T. Ntawm lawv, S, R, B yog cov hlau zoo nkauj, thaum N, K, E, J, T yog lub hauv paus hlau thermocouples.
Hom S: oxidation kuj zoo heev, haum rau kev siv tas li hauv oxidizing thiab inert cua. Kev khiav hauj lwm kub tsis tu ncua: 1400 degree, luv -lub sij hawm: 1600℃. Nws muaj qhov tseeb tshaj plaws ntawm tag nrho cov thermocouples thiab feem ntau yog siv los ua tus qauv thermocouple.
Hom R: Zoo ib yam li Hom S hauv yuav luag txhua yam khoom, tshwj tsis yog tias nws cov thermoelectric EMF yog kwv yees li 15% siab dua.
Hom B: Tsis tshua muaj hluav taws xob EMF ntawm chav tsev kub, yog li kev them nyiaj xaim feem ntau tsis tas yuav ntsuas. Kev khiav hauj lwm kub: 1600 degree, luv -lub sij hawm: 1800℃. Nws tuaj yeem siv rau hauv oxidizing lossis nruab nrab cua, thiab tseem nyob hauv lub tshuab nqus tsev rau lub sijhawm luv.
Hom N: Zoo heev - kub oxidation tsis kam mus txog 1300 degree, zoo ntev - lub sij hawm stability ntawm thermoelectric EMF thiab repeatability nyob rau hauv luv luv - lub sij hawm thermal cycling, zoo hluav taws xob kuj thiab tsawg - kub tsis kam. Nws tuaj yeem hloov pauv hom S thermocouples.
Hom K: Muaj zog oxidation tsis kam, haum rau kev siv txuas ntxiv hauv oxidizing thiab inert cua. Kev khiav hauj lwm kub tsis tu ncua: 1000 degree, luv -lub sij hawm: 1200℃. Nws yog cov thermocouple feem ntau siv.
Hom E: Muaj qhov loj tshaj plaws thermoelectric EMF (siab tshaj plaws) ntawm cov thermocouples. Haum rau kev siv txuas ntxiv hauv oxidizing thiab inert cua, kev khiav hauj lwm kub: 0-800 degree.
Hom J: tuaj yeem siv rau hauv ob qho tib si oxidizing atmospheres (max{0}} degree) thiab txo cov huab cua (max{1}}℃). Resistant corrosion los ntawm hydrogen thiab carbon monoxide, dav siv nyob rau hauv roj av refining thiab tshuaj industries.
Hom T: Muaj qhov raug siab tshaj plaws ntawm txhua lub hauv paus hlau thermocouples, feem ntau yog siv rau kub hauv qab 300 degree.
