Cov yam ntxwv ntawm K-Hom Thermocouple

K-hom thermocouple yog ib qho ntsuas kub uas tau siv nrog cov twj paj nruag tso tawm, kaw cov cuab yeej siv hluav taws xob, thiab cov neeg siv hluav taws xob. K-hom thermocouplets tam sim no feem ntau siv tus nqi qis tsawg ntawm cov nqi hlau thermocouple, nrog kev siv sib npaug ntawm cov lej ntawm kev thermocouples. K-hom thermocouples muaj peev xwm ncaj qha ntsuas qhov chaw kub ntawm cov kua dej thiab roj av, xws li cov khib nyiab, xws li} degree rau ntau cov txheej txheem ntau lawm. K-hom thermocouples feem ntau muaj qhov kub thiab txias cov ntsiab lus, mounting constures, thiab cov thawv tshuam kev tshuam, ntawm lwm cov khoom tseem ceeb. K-hom thermocots muaj qhov zoo ntawm linearity zoo, siab siab thiab kev sib txawv, muaj zog tiv thaiv oxidation, thiab tus nqi tsawg. Lawv tuaj yeem yog siv dav siv los ntawm cov neeg siv hauv oxidizing intert atcospheres.
Thermocouples yog ib qho ntawm cov feem ntau siv cov kev kub siv kub thiab siv tau feem ntau siv tau cov khoom sib xyaw hauv kev lag luam. Cov twj paj nruag thib ob yuav tsum tau nruab, uas muaj cov txiaj ntsig zoo hauv qab no:
① ntsuas siab ntsuas qhov yog. Vim tias Thermocouple yog nyob rau hauv kev sib cuag ncaj qha nrog ntsuas ntsuas thiab tsis cuam tshuam los ntawm cov nruab nrab hauv nruab nrab.
Tsis tshua muaj kev ntsuas ntau yam. Feem ntau siv thermocouples muaj peev xwm ntsuas tsis tu ncua los ntawm {}}}} {}}}} degree (xws li tungsten rhenium).
Siv kev siv tau yooj yim thiab siv tau yooj yim. Thermocouples feem ntau muaj ntawm ob hom hlau hlau, thiab tsis txwv los ntawm qhov loj me lossis qhib. Lawv muaj tes tsho tiv thaiv sab nraud, ua rau lawv siv yooj yim heev.
Xaiv thermocouples nrog cov cim sib tw raws li qhov ntsuas kub thiab ntsuas kub thiab raug
Thaum kev ua haujlwm kub yog nruab nrab ntawm 1300 ~ 1800 degree thiab siab precision yog qhov yuav tsum tau, B-hom thermocouples feem ntau xaiv; Qhov yuav tsum tau ua rau qhov raug yog tsis yog, thiab cov cua tso cai rau kev siv lub tungsten rhenium thermoco thermocouples. Feem ntau, tungsten rhenium thermocots yog xaiv rau qhov kub siab tshaj 1800 degree; S-hom thermocouples thiab n-hom thermoounles muaj rau siv nyob rau ntawm qhov kub kub txij 1000 txog 1300 degree, uas yuav tsum muaj qhov tseeb; K-hom thiab n-hom thermocouples feem ntau siv qis dua 1000 degree, thaum e-hom e-hom e-hom e-hom ntawv thermocoup feem ntau yog siv qis dua 400 degree; Ntawm 250 degree thiab cov ntsuas kub tsis zoo, T-hom thermocouples feem ntau siv. Ntawm tsawg kub, T-hom thermocouples yog ruaj khov thiab muaj qhov tseeb.
