Dab tsi yog cov ntsiab cai ua haujlwm ntawm thermocouples thiab thermal resistors?

1. Thermocouple

Thaum ob tus neeg sib txawv lossis cov semiconductors A thiab nws ob xaus tau sib txawv los yog qhov kawg ntawm lub t, nws yog qhov kawg ntawm t, nws yog qhov kawg ntawm lub zog hluav taws xob yuav tsim tawm hauv Circuit Court, thiab Kev taw qhia thiab qhov ntau ntawm lub zog hluav taws xob muaj feem xyuam rau cov khoom ntawm tus neeg xyuas pib thiab ntsuas kub ntawm ob lub nodes.

Qhov tshwm sim no hu ua "Thermoelectric nyhuv", thiab lub Circuit Court tsim ntawm ob tus cwj pwm hu ua "thermocouple". Ob tug cwj pwm no hu ua "Thermoelectric ncej", thiab cov tsim hluav taws xob hauv hluav taws xob yog hu ua "thermoelectric peev xwm".

2. Thermal Kuj

Qhov ntsuas kub ntawm kev ua haujlwm ntawm thermal tiv thaiv yog raws cov yam ntxwv uas cov kev hloov pauv ntawm cov ntsuas kub kom ntsuas kub thiab kub hais txog qhov ntsuas kub thiab txias. Tus cua kub feem ntau yog ua los ntawm cov ntaub ntawv hlau ntshiab, nrog platinum thiab tooj tau dav siv. Tam sim no, cov khoom siv xws li npib tsib xee, manganese, thiab rhodium tau txais yuav los ua cov cua sov. Tus cua sov feem ntau yuav tsum tau kis tus kab mob los ntawm kev tawm tsam los ntawm kev coj mus rau lub computer tswj khoom lossis lwm yam kev ntsuas theem nrab.

Cov Ntaub Ntawv Ntxiv:

Qhov sib txawv ntawm thermocouples thiab thermal resistors:

1, rau ntawm qhov chaw txiav txim hauv kev ua haujlwm

Thermocouces muaj cov kab lis zoo thiab tsis zoo thiab them cov xov hlau kuj muaj cov qauv zoo thiab tsis zoo. Ua ntej, xyuas kom muaj kev sib txuas tau zoo thiab kev teeb tsa hauv kev ua haujlwm. Cov uas muaj xws li Circuit Court, qhib Circuit Court, kev sib cuag tsis zoo (kev txiav txim los ntawm kev sib txuam nrog), thiab detheration (txheeb xyuas los ntawm cov xim saum npoo).

Thaum kuaj xyuas, Thermocouple yuav tsum tau sib cais los ntawm cov meterary theem ob. Siv ib qho cuab yeej ua kom luv luv ntawm cov xaim hluav taws xob cov xaim hluav taws xob ntawm cov meterary meter. Lub ntsuas ntsuas yuav tsum qhia lub chav tsev kub, thiab tom qab ntawd Circuit Court lub thermocouple wiring davhlau ya nyob twg. Lub ntsuas ntsuas yuav tsum qhia tau qhov kub qhov twg qhov thermocouple yog nyob (yog tias tsis yog, cov xaim hluav taws xob yog faulty). Siv ib tug sib ntau sib luag ntawm kev kwv yees kwv yees lub peev xwm thermoelectric (yog tias ib txwm, thov tshawb xyuas cov txheej txheem).

Lub motiveter tuaj yeem siv los tshawb xyuas cov kab luv luv thiab qhib cov voj voog hauv thermal resistors. Hauv kev ua haujlwm, yog tias muaj kev xav tsis thoob, tsuas yog tshem cov hlau xaus los ntawm lub resistor kawg thiab tshawb xyuas cov twj tso tawm. Yog tias nws mus txog ib tus nqi loj, lub thermal resistor yuav luv-corrcuitacter rov qab los, thiab thaum muaj kev sib txuas lus luv luv, qhia tau tias lub raj tiv thaiv qis dua, muaj qhov tsis muaj dej nyab thiab cov zaub yuav loj heev. Lub thermal thaiv cov hluav taws xob yuav tso tawm ib qho me me luv cellCuitcuit.

2, los ntawm cov khoom pom zoo, thermal kuj yog ib hom khoom siv hlau uas rhiab rau qhov kub hloov. Thermocouples yog cov ntaub ntawv bimetallic, uas muaj ob qho sib txawv tsim cov peev xwm sib txawv ntawm ob lub xov hlau sib txawv vim qhov ntsuas kub.

3, cov kub li cas thiaj pom los ntawm ob lub sensors sib txawv. Thermal kuj feem ntau kuaj qhov kub ntawm 0-150 thermorotures tuaj yeem ntes qhov kub ntawm {2}} degrees (lossis siab dua). Yog li ntawd, cov qub yog rau kev kuaj ntsuas qis, thaum tom kawg yog rau kev kuaj kom kub siab.
