Yuav ua li cas tuaj yeem siv hluav taws xob ntawm lub thermocouple tau txais
Tso lus
1. Electromotive quab yuam ntawm thermocouple
Thermocoter yog sensors uas tuaj yeem hloov lub zog thermal rau hauv lub zog hluav taws xob thiab siv dav hauv kev ntsuas kub. Hauv thermocoenples, vim muaj cov teebmeem thermoelectric, lub thermoelectric muaj peev xwm los ntawm qhov kub tsis sib xws tuaj yeem raug ntsuas thiab qhov ntau ntawm cov qhov sib txawv.
Ib lub thermocouple yog muaj cov xov hlau uas muaj los ntawm ob cov khoom sib txawv, uas yog welded ua ke los ua khub electrode. Thaum muaj qhov sib txawv kub ntawm ob daim ntawv taws kev sib tw, cov peev xwm thermoeltric yog tsim ntawm cov xov hlau. Qhov no yog vim qhov sib txawv thermoelectric coefficients ntawm ob hom xaim, uas ua rau muaj qhov sib txawv tshwm sim los ntawm qhov kub.
Muab xam cov kab rau kev sib zog hluav taws xob ntawm thermocouple
Lub zog hluav taws xob ntawm lub thermocouple tuaj yeem suav tau siv cov qauv hauv qab no:
△E=S×△T
Ntawm lawv, Δ e sawv cev ntawm lub zog hluav taws xob ntawm thermocouple, s sawv cev rau qhov rhiab ntawm qhov sib txawv ntawm qhov sib txawv ntawm ob lub qhov sib txawv.
Rhiab ntawm thermocouple
Qhov rhiab heev ntawm qhov ntsuas hluav taws xob ntawm lub thermocouple yog hais txog qhov ntau ntawm lub tshuab hluav taws xob yuam kev los ntawm ib chav tsev kub sib txawv. Cov khoom siv thermocoup sib txawv muaj cov sib txawv rhiab, yog li xaiv ntawm thermocoumles yuav tsum tau ua raws cov cai tshwj xeeb.
2. Yuav ua li cas kom tau txais lub tshuab hluav taws xob ntawm lub thermocouple
Txhawm rau kom tau txais lub tshuab hluav taws xob ntawm lub thermocouple, cov kauj ruam hauv qab no yuav tsum muaj:
Qhov kub sib txawv ntawm ob lub tshuab vuam tuaj yeem ntsuas tau siv cov cuab yeej xws li cov cua sov.
Qhov rhiab heev ntawm ib lub thermocouple tuaj yeem txiav txim los ntawm kev sab laj uas muaj feem cuam tshuam lossis phau ntawv qhia ntawm thermocrouple.
Los ntawm hloov qhov kub sib txawv sib txawv rau hauv lub tshuab hluav taws xob ua cov txheej ntawm thermocouple, lub tshuab hluav taws xob hauv lub thermocrouple tuaj yeem tau txais.
Los ntawm cov kauj ruam saum toj no, peb tuaj yeem tau txais lub zog hluav taws xob ntawm thermocouple thiab txuas ntxiv xam qhov sib txawv qhov sib txawv ntawm ob lub vuam cov ntsiab lus.
Nws yuav tsum raug sau tseg tias nyob rau hauv cov ntawv thov siv, ntsuas ntawm thermocoodles yog cuam tshuam los ntawm ntau yam xaim ntev, txoj kev tsheb sib tw, thiab ib puag ncig txoj kev, thiab ib puag ncig txoj kev, thiab ib puag ncig ntawm chav kawm, thiab ib puag ncig ntawm txoj kev sab nraud. Yog li ntawd, sib raug ntsuas kev ntsuas thiab kho kom raug rau hauv cov kev ntsuas tshwj xeeb.
