Yuav ua li cas paub qhov txawv ntawm Thermocouple thiab Tus Phooj Ywg
Ua ntej tshaj plaws, cia peb qhia thermocouples. Thermocouples yog cov feem ntau siv cov cuab yeej kub hauv kev ntsuas kub. Lawv cov yam ntxwv tseem ceeb suav nrog kev ntsuas dav dav, cov qauv ruaj khov, thiab muaj peev xwm los hloov cov cim hluav taws xob remotely, ua rau nws yooj yim rau kev tswj hwm thiab tswj tau.

Qhov ntsuas kub ntsuas ntawm cov thermocokas yog raws li cov nyhuv thermoelectric nyhuv. Txuas ob tus neeg sib txawv lossis cov semiconductors rau hauv qhov chaw kaw, thaum qhov kub sib txawv ntawm ob lub junctionss tshwm sim, lub peev xwm thermoelectric yuav tshwm sim hauv Circuit Court. Qhov tshwm sim no hu ua thermoelectric nyhuv, tseem hu ua Showbeck nyhuv.

Lub thermoelectric peev xwm tsim nyob rau hauv ib tug kaw Circuit Court muaj ob hom hluav taws xob muaj peev xwm; Thermoelectric peev xwm thiab kev ua rog muaj peev xwm. Thermoelectric muaj peev xwm hais txog lub peev xwm hluav taws xob uas tshwm sim ntawm ob xaus ntawm tus neeg saib xyuas kev sib koom tes vim qhov ntsuas kub sib txawv. Cov neeg sib txawv muaj hluav taws xob sib txawv, yog li lawv cov peev xwm hluav taws xob tsis zoo li qub. Kev ua tsov ua rog, hais txog lub peev xwm hluav taws xob tsim thaum muaj ob tus neeg sib txawv ntawm kev ua tsov ua rog, vim muaj qhov sib txawv ntawm cov tshuab hluav taws xob. Thaum lawv mus txog ib qho kev sib txig sib luag, qhov ntau ntawm kev ua tsov ua rog nyob ntawm cov yam ntxwv ntawm ob tus neeg sib txawv thiab qhov kub ntawm lawv qhov kub ua tsov ua rog.

Muaj qhov ntsuas ntsuas rau cov thermocouples tam sim no uas tau muab faib ua yim qhov sib cais tau kub txog li minus 270 degrees Celsius rau siab li 1800 degrees Celsius. Ntawm lawv, B, R, thiab Syde rau lub platinum series thermoounles vim platinum yog ib qho khoom siv platinum thiab tseem paub tias yog cov khoom siv hlau thermoco.

Thiab tus so yog hu ua pheej yig hlau thermocouples. Muaj ob hom kev siv hluav taws xob thermocouple: hom dav dav thiab hom ua rog. Raug thermoco yog tsim tau ntau yam xws li cov hluav taws xob ntau li cov pa hluav taws kub, rwb thaiv tsev hlab, thiab cov thawv tshuam kev sib tshuam. Cov cuab yeej thermocoed thermoco yog kev sib xyaw ua ke ntawm thermocouple xaim, rwb thaiv tsev cov ntaub ntawv, thiab kev sib tsoo thiab ncab los ntawm kev ua.
