T-hom thermocouple cov ntaub ntawv thiab cov yam ntxwv

T-hom thermocouple, uas yog, tooj-tooj-npib thermocouple, kuj muaj qhov ntsuas kub thiab txias thiab kub}. {}}. 872mv. T-hom thermocouple yog ib qho zoo tshaj thermocouple rau kev ntsuas qis tsawg-kub pheej yig meters, feem ntau yog siv hauv kev ua tub rog kev lag luam. Nws qhov zoo electrode (TP) yog 99.95% Ntshiab tooj liab, thiab nws qhov tsis zoo electrode (55% tooj liab {15}}% npib tsib xee).

T-hom thermocouple muaj qhov zoo ntawm linearity zoo, loj qhov tseeb, siab homogeneity ntawm thermocouple xaim, thiab tus nqi qis. Nws yog qhov haum rau kev txo cov huab cua, tshwj xeeb tshaj yog thaum muaj kub tsawg ntawm -200 ~ 0 degree. Nws muaj cov yam ntxwv zoo thiab muaj kev ruaj khov zoo dua. Qhov kev ruaj ntseg txhua xyoo tuaj yeem tsawg dua ± 33v. Tom qab cov lus qhia tsawg-ntsuas kub, nws tuaj yeem siv ua tus qauv thib ob-chav kawm rau kev hloov pauv kub tsawg. Vim tias tooj liab muaj cov oxidation tsis zoo nyob rau ntawm qhov kub thiab txias thiab yog qhov yooj yim poob, nws feem ntau yog siv tsis pub dhau 300 degree. Thaum qhov kub thiab txias nyob rau hauv qab {{8} degree, lub thermoelectric peev xwm txo sai ntawm tooj liab yog siab, uas yooj yim qhia txog qhov tsis raug ntawm tsawg kub. Qib thev taus qib tau muab faib ua cov iiiiiii, qhov twg qib kuv yog qhov siab tshaj plaws theem.
