Hauv lub ntiaj teb nyuaj ntawm kev ntsuas kub,cov xov hlau thermocoupleua haujlwm ua cov phab ej tsis muaj npe nrov, ua kom muaj kev nyeem kub kom raug thiab txhim khu kev qha thoob plaws ntau yam lag luam. Hauv plawv ntawm lawv txoj haujlwm yog ib qho tseem ceeb - cov lej xim rau cov xov hlau thermocouple. Tab sis cov lej xim no yog dab tsi, thiab vim li cas nws thiaj tseem ceeb?
Cov xim code rau cov hlau thermocouple yog ib qho system uas tau tsim los kom paub qhov txawv ntawm ntau hom thermocouples. Txhua hom thermocouple yog tsim los ntawm kev sib xyaw ua ke ntawm cov hlau, uas tsim cov hluav taws xob tshwj xeeb uas sib haum rau qhov kub tshwj xeeb. Cov xim - coding system no ua haujlwm ua ib hom lus thoob ntiaj teb rau cov kws kho tshuab thiab cov engineers, uas tso cai rau lawv kom paub sai sai txog hom hlau thermocouple uas lawv tab tom tuav. Los ntawm kev ua kom muaj kev sib txuas zoo raws li cov xim code, nws lav qhov nyeem kub txhim khu kev qha, tiv thaiv kev ua yuam kev kim thiab lub sijhawm tsis ua haujlwm.
Cia peb kawm ntxiv txog qee hom thermocouple uas siv ntau tshaj plaws thiab lawv cov xim sib txuas. Cov hlau thermocouple Hom J, nrog nws cov ceg hlau zoo thiab ceg tsis zoo tas li, yooj yim paub los ntawm nws cov xim coding. Cov hlau zoo yog cim nrog dawb, thaum cov hlau tsis zoo yog liab. Hom no feem ntau siv rau hauv cov ntawv thov xws li cov cub tawg thiab cov qhov cub, qhov twg nws tuaj yeem tiv taus qhov kub thiab txias siab thiab muab cov ntawv nyeem raug.
Hom K, tej zaum yog cov thermocouple uas siv ntau tshaj plaws niaj hnub no, muaj ib ceg chromel zoo thiab ib ceg alumel tsis zoo. Cov xov hlau zoo ntawm Hom K yog xim daj, thiab cov xov hlau tsis zoo yog xim liab. Paub txog nws qhov kub thiab txias dav thiab kev ruaj khov zoo heev, Hom K thermocouples feem ntau siv rau hauv ntau yam txheej txheem kev lag luam, suav nrog kev ua hlau, kev tsim hluav taws xob, thiab kev ua tshuaj lom neeg.
Rau qhovHom T thermocouple hlau, uas muaj ib ceg tooj liab zoo thiab ib ceg tsis zoo tas li, cov xov hlau zoo yog xiav, thiab cov xov hlau tsis zoo yog liab. Hom no zoo rau cov ntawv thov kub qis, xws li hauv cov tshuab tub yees thiab kev saib xyuas ib puag ncig, vim nws qhov tseeb siab hauv qhov kub qis dua.
Ntawm Tankii, peb muaj kev txaus siab rau peb txoj kev cog lus rau qhov zoo tshaj plaws thaum nws los txog rau cov khoom siv hlau thermocouple. Peb cov hlau thermocouple ua raws li cov qauv xim thoob ntiaj teb, kom ntseeg tau tias muaj kev sib raug zoo nrog cov txheej txheem ntsuas uas twb muaj lawm thoob ntiaj teb. Qhov no tsis yog tsuas yog ua kom yooj yim rau cov txheej txheem teeb tsa tab sis kuj tseem txo qhov kev pheej hmoo ntawm kev sib txuas tsis raug.
Ua los ntawm kev siv cov khoom siv zoo tshaj plaws, peb cov xov hlau thermocouple zoo muaj kev ua tau zoo tshaj plaws. Lawv tau tsim los muab kev ntsuas kub kom raug thiab ruaj khov thoob plaws ntau yam kev siv. Txawm hais tias koj ua haujlwm hauv qhov chaw xav tau ntawm kev tsim khoom lag luam, qhov yuav tsum tau ua kom raug ntawm kev ua zaub mov, lossis thaj chaw tshwj xeeb ntawm kev tshawb fawb, peb cov khoom siv thermocouple ntau yam tau pab koj. Txhua yam khoom tau txheeb xyuas meej los ntawm cov lej xim txheem, uas tso cai rau kev txheeb xyuas sai thiab yooj yim, yog li koj tuaj yeem ntseeg siab tag nrho rau qhov tseeb ntawm koj qhov kev ua haujlwm kub.
Xaus lus, cov xim code rau thermocouple hlau tsis yog tsuas yog ib qho qhia pom xwb; nws yog ib qho tseem ceeb hauv kev ntsuas kub. Nrog peb cov khoom siv thermocouple hlau txhim khu kev qha thiab ua tau zoo, koj tuaj yeem paub tseeb tias koj cov haujlwm saib xyuas kub yuav raug ua tiav nrog qhov tseeb thiab ua haujlwm tau zoo tshaj plaws, ua rau koj muaj peev xwm txiav txim siab tau zoo thiab ua kom koj cov haujlwm khiav tau zoo.
