Cov yam ntxwv thermoelectric ntawm thermocouples yog txiav txim los ntawm ob yam

Cov yam ntxwv thermoelectric ntawm thermoounces xa mus rau qhov tshwm sim uas muaj peev xwm hluav taws xob sib txawv yog tsim nyob rau hauv lub rooj sib ze ntawm ob coals ntawm ib qho kub.

1. Qhov loj ntawm Thermocouple Voj cov khoom tsuas yog cuam tshuam nrog cov khoom muaj peev xwm thiab qhov kub thiab txias, thiab tsis muaj dab tsi ua rau qhov ntev thiab tuab ntawm cov thermocouple.
2. Tsuas yog ob tug neeg sib txawv ntawm cov khoom sib txawv tuaj yeem ua qhov thermocouple; Thaum lub ntsuas kub ntawm ob qho kawg ntawm thermocouple sib txawv, lub peev xwm thermoeltric yuav tsim tawm. Ob yam dab tsi uas txiav txim siab cov yam ntxwv thermoelectric ntawm thermocouples? 3. Tom qab cov khoom siv tau txiav txim siab, qhov loj me ntawm lub peev xwm thermoelectric tsuas yog cuam tshuam nrog qhov kub ntawm thermocouple.

Thermocouple kev hloov kho kev kho mob

Txij li qhov ntsuas kub-thermoelectric muaj peev xwm nkhaus (thermocouple vease ntawm qhov ntsuas yuav tsum raug kho. Yog tias qhov kawg kub kawg ntawm Thermocouple yog t, thiab txias txias txias yog tn hloov ntawm {}} muaj peev xwm ntawm thermocouple yog e (t, tn). Raws li cov kev cai ntsuas kub hauv nruab nrab E (T, {{{} {{{{{{{{{{{{{ Nws yuav tsum tau sau tseg tias vim tsis muaj kev cuam tshuam ntawm cov thermocouple kub muaj peev xwm nkhaus, qhov sib ntxiv los ntawm kev sib ntxiv ntawm thermoelectric muaj peev xwm, tsis yog qhov yooj yim ntxiv.

Piv txwv li: thaum siv npib tsib xee-chromium-Npib-Silicon Thermocouple los ntsuas kub, qhov txias txias ntawm thermocouple yog tn {}}} degree. Lub thermoelectric muaj peev xwm e (t, tn)=40. 347 MV yog ntsuas thaum txias txias yog 3 {{{}} degree. Lub thermoelectric muaj peev xwm e (tn, {{{{{} {= 1. Tom qab ntawd e (t, o) {12}} e (t, tn) + e (347 + 1. 203) mv {}}. 55 MV. Ib yam li ntawd, t {20}}} degree yog pom los ntawm nplai.

Tus txheej txheem yooj yim ntawm thermocouple kub ntsuas yog tias ob tug cwj pwm ntawm cov khoom sib txawv ua ib lub voj kaw. Thaum muaj qhov ntsuas kub ntawm ob qho kawg, tam sim no yuav ntws los ntawm lub voj. Nyob rau lub sijhawm no, muaj lub zog hluav taws xob ntawm ob xaus - Thermoelectric lub zog hluav taws xob lub zog, uas yog qhov thiaj li hu ua cov nyhuv pom. Ob homogeneous kev coj ntawm cov khoom sib txawv yog thermocouples. Qhov kawg nrog qhov kub siab dua yog qhov ua haujlwm kawg, thiab qhov kawg nrog qhov kub qis dua yog qhov kawg. Qhov kawg xaus feem ntau yog nyob rau ntawm qhov kub tsis tu ncua. Raws li kev sib raug zoo ntawm thermoelectric muaj peev xwm thiab kub, lub ntsuas cua sov yog tsim; Cov nplai tau txais thaum kawg xaus kub yog 0 degree, thiab sib txawv thermocouces muaj cov nplai sib txawv.

Thermocoter yog sensors uas ntsuas kub raws li cov nyhuv thermoelectric thiab siv tau siv ntsuas kub hauv qhov ntsuas kub. Cov tsos ntawm ntau thermocouples feem ntau sib txawv vim yog xav tau, tab sis lawv cov qauv theem pib yog ntxig tib yam. Lawv feem ntau yog tsim ntawm qhov tseem ceeb xws li thermoounters, insulating tes tiv thaiv txoj hlab, cov ntaub ntawv digital, sau cov cuab yeej siv thiab tshuab hluav taws xob.
