Koj puas paub lub ntsiab cai ntawm thermocouple kub ntsuas?

Kev tshawb fawb thiab kev txhim kho ntawm ib feem loj ntawm cov cuab yeej ntawm qhov zoo tshaj plaws-muag cov khoom siv kub ntawm kev ua lag luam yog raws li cov qauv ntawm cov thev naus laus zis thev naus laus zis.Thermocoupleyog qhov ntsuas kub siab thiab yog thawj qhov kev ntsuas uas tau ntsuas kub thiab hloov pauv qhov ntsuas kub mus rau qhov ntsuas kub los ntawm kev ntsuas hluav taws xob.

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, qhov tam sim no yuav dhau los ntawm lub voj. Lub sijhawm no, muaj ib lub peev xwm thermoelectric ntawm ob xaus, uas yog qhov thiaj li hu ua cov nyhuv pom.

Ob homogeneous tus neeg coj ntawm cov khoom sib txawv yog thermocouples. Qhov kawg nrog qhov kub siab dua yog qhov ua haujlwm tiav, thiab qhov kawg nrog qhov kub qis 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 rooj thermocouple kawm tiav; Cov rooj kawm tiav yog tau thaum kub ntawm qhov kawg ntawm qhov kawg yog 0 ℃. Sib txawv thermocouples muaj cov ntawv kawm tiav tiav.

Thaum ib qho khoom siv hlau txuas nrog lubthermocoupleVoj, ntev li ntev tau qhov kub ntawm ob lub junctionss ntawm cov khoom yog tib yam, lub thermoelecle yuav nyob twj ywm tsis hloov, uas yog, nws yuav tsis cuam tshuam los ntawm tus thib peb hlau txuas rau lub voj. Yog li ntawd, thaum ntsuas ntsuas ntsuas kub ntawm thermocouple, ntsuas ntsuas yuav tau txuas. Tom qab ntsuas qhov ntsuas hluav taws xob thermoelectric, qhov ntsuas kub ntawm qhov nruab nrab ntsuas tau tuaj yeem paub. Thermocouple Wels ob tus neeg coj lossis semiconductors A thiab B ntawm cov khoom sib txawv los ua lub voj kaw.

Thaum ob qho ntawm ob qho kev sib txawv yog txuas rau ntawm ob qho kawg los ua lub voj, thaum qhov kub ntawm lub zog hluav taws xob yuav tsim tawm hauv lub voj. Qhov tshwm sim no hu ua cov nyhuv thermoelectric, thiab lub zog hluav taws xob no hu ua lub peev xwm thermoelectric.Qhov cua ThermocoSiv lub ntsiab cai no ntsuas ntsuas kub. Ntawm lawv, qhov kawg ncaj qha siv los ntsuas qhov kub ntawm lub nruab nrab yog hu ua txoj haujlwm kawg, thiab lwm qhov kawg yog hu ua qhov kawg; Lub sijhawm txias txias tau txuas nrog cov twj paj nruag tso tawm los yog cov twj paj nruag sib piv, thiab cov twj paj nruag tso tawm yuav qhia tau tias yog Thermocouple. Thermocouple yog qhov tseeb ib lub zog hloov pauv uas converts tshav kub kub rau hauv hluav taws xob lub zog thiab siv cov khoom siv thermoelectric kub. Rau lub thermoelectric muaj peev xwm ntawm thermocouple, ntau yam teeb meem yuav tsum raug sau tseg. 

1. Cov thermoelectric muaj peev xwm ntawm thermocouple yog qhov sib txawv ntawm qhov kub thiab txias, tsis yog txoj haujlwm ntawm qhov kub ntawm qhov sib txawv ntawm cov thermocouple; 

2. Qhov loj me ntawm thermoelectric peev xwm tsim los ntawm thermocouple tsis muaj ib yam dab tsi los ntawm thermocouple khoom thiab qhov kub ntawm qhov sib txawv ntawm ob qho kawg; 

3. Thaum cov khoom muaj pes tsawg leeg ntawm ob lub qhov hluav taws xob thermocouple yog txiav txim siab ntawm thermocoupricuple yog tsuas muaj feem cuam tshuam rau qhov kub ntawm qhov sib txawv; Yog hais tias qhov ntsuas kub ntawm qhov txias txias kawg ntawm lub thermocouple yog key, lub peev xwm thermoellepric tsuas yog ib qho nuj nqis ntawm kev ua haujlwm sov.
