Xam txheej txheem rau cov peev xwm sib txawv tsim los ntawm thermocouple
Tso lus
1. Cov txheej txheem yooj yim ntawm thermocouple
Thermocouple yog ib qho siv tau siv ntsuas ntsuas uas siv cov hauv paus ntsiab lus ntawm thermoelectric cuam tshuam rau ntsuas kub. Thermoelectric txiaj ntsig yog hais txog qhov sib txawv tshwm sim los ntawm qhov kub tsis sib txawv thaum ob yam hlau sib txawv tau txuas nrog ua ke.
2. Qauv ntawm thermocouples
Nyob rau hauv dav dav, ib tug thermocouple yog tsim ntawm ob lub xov hlau ua los ntawm cov khoom sib txawv, thiab kev sib txuas ntawm cov xov hlau no hu ua qhov chaw kub. Cov ntaub ntawv uas siv rau thermocouples muaj tooj liab thiab tooj liab alloys, hlau thiab tas li, li platinum thiab iridium. Kev xaiv ntawm cov ntaub ntawv no yog raws li kev ntsuas ntsuas kub thiab ntsuas ib puag ncig.
3. Ua haujlwm ua haujlwm ntawm thermocouple
Tus txheej txheem ua hauj lwm ntawm thermocouple yog raws li cov nyhuv thermoelectric nyhuv. Thaum muaj qhov sib txawv ntawm cov hotspots ntawm ob lub xov hlau ntawm lub thermocouple, qhov sib txawv yog tsim. Qhov sib txawv no cuam tshuam los ntawm qhov kub sib txawv, thiab feem ntau, qhov sib txawv loj dua, muaj peev xwm loj dua rau cov muaj peev xwm tsim tau.
4. Kev Xam Cov Xam ntawm Thermocouple muaj peev xwm sib txawv
Txhawm rau laij cov peev xwm los ntawm thermocouple, ob lub ntsiab lus tseem ceeb yuav tsum tau to taub: Qhov kub sib txawv ntawm qhov kub thiab txias thiab lub thermoelectric coefficient.
Qhov kub ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov kub ntawm ob lub xov hlau ntawm lub thermocouple. Nquag, qhov sib txawv kub sib txawv tuaj yeem raug ntsuas los ntawm qhov kub thiab txias.
Thermoelectric ob peb coeffici graint hais txog kev sib raug zoo sib xws ntawm lub thermoelectric kev hloov pauv thiab kub hloov ntawm thermocouple hlau cov ntaub ntawv. Cov ntaub ntawv sib txawv hlau muaj cov coefficiecectric sib txawv. Lub thermoelectric coefficient tuaj yeem tau los ntawm cov ntaub ntawv muab los ntawm cov ntaub ntawv siv lossis cov ntaub ntawv ntsig txog.
Muaj peev xwm sib txawv =} thermoeltric coefficient X qhov txawv.
5. Daim ntawv thov ntawm thermocouples
Thermocouces muaj ntau cov kev siv, suav nrog cov ntsuas ntsuas kub, ntsuas kub thiab hloov lub zog. Thermocouples yog feem ntau siv nyob rau hauv kev lag luam tshuab automation, tshuaj lom neeg, hlau metallurgical, roj av, thiab tshuaj lag luam. Lub caij no, thermouples tseem dav siv nyob rau hauv chaw soj nstuam thiab kev tshawb fawb.
Cov yam ntxwv ntawm thermocotres yog kev ntsuas dav ntau, cov lus teb ceev ceev, thiab siv yooj yim. Txawm li cas los xij, thermocouples kuj muaj qee qhov kev txwv, xws li ua kom tsawg thiab nkag siab rau hluav taws xob cuam tshuam.
Thermocouple yog ib qho kev ntsuas uas siv lub hauv paus ntsiab lus ntawm thermoelectric nyhwv kom ntsuas kub. Thermoroup tsim lub peev xwm sib txawv los ntawm ntsuas qhov sib txawv ntawm qhov sib txawv ntawm cov khoom kub ntawm luminescts ntawm cov khoom siv luminescent, yog li ntsuas kub. Cov mis rau xam muaj peev xwm sib txawv yog qhov sib txawv =} thermoelectric ob peb coefficient X qhov txawv. Thermocouces muaj ntau cov kev siv, tab sis kuj muaj qee qhov kev txwv. Los ntawm kev siv thermocouples, peb tuaj yeem ntsuas tau zoo dua thiab tswj qhov kub thiab txias.
