Dab tsi yog qhov sib txawv ntawm ntau hom kev ntsuas kub?

Nyob rau hauv lub sector ntawm qhov kub thiab txias, ob peb gadgets muaj, txhua tus nrog nws tus kheej cov yam ntxwv. Daim duab ntau lub panorama ntawm cov txheej txheem kev lag luam, kev sim kho mob, thiab cov kev pabcuam tsis tu ncua, suav nrog cov cuab yeej ntsuas kub sib txawv. To taub qhov txawv ntawm cov gadgets yog qhov tseem ceeb rau kev xaiv kom raug.
Thermocouples yog ib qho ntawm cov khoom siv ntsuas kub uas feem ntau siv. Lawv paintings feem ntau raws li tag nrho ntawm cov lus qhuab qhia ntawm Seebeck nyhuv, nyob rau hauv uas ib tug voltage yog generated whilst txawv hlau yog koom nyob rau hauv txawv kub. Thermocouples raug lees paub rau nws qhov kub thiab txias ntau yam, durability, thiab cov nqi sib piv. Piv txwv li, hom K thermocouples tuaj yeem ntsuas qhov kub ntawm -200 degree txog 1372 degree . Lawv tau siv tsis tu ncua nyob rau hauv cov chaw lag luam uas muaj qhov kub thiab txias ntau dhau thiab ib puag ncig siab phem.
Resistance temperature detectors (RTDs) ua haujlwm ntawm cov lus qhuab qhia hais tias qhov hluav taws xob tsis kam ntawm cov hlau hloov nrog qhov kub thiab txias. RTDs yog qhov tseeb thiab ruaj khov, nthuav qhia kev nyeem ntawv tshwj xeeb tshaj li cov thermocouples hauv ntau qhov xwm txheej. Lawv kuj raug tsim txom ntau dua los ntawm kev hloov kho hauv ib puag ncig. Txawm li cas los xij, RTDs feem ntau yog tus nqi qis dua thiab muaj qhov nqaim ntau yam. Piv txwv li, platinum RTDs feem ntau yog siv hauv chav kuaj thiab cov kev pab cuam me me.
Infrared thermometers degree qhov kub thiab txias ntawm txoj kev ntawm kev kuaj xyuas infrared hluav taws xob tawm ntawm txoj kev ntawm ib yam khoom. Lawv yog cov khoom siv uas tsis yog kov, uas ua rau lawv zoo tshaj plaws rau kev ntsuas qhov ntsuas kub ntawm kev hloov khoom siv lossis hauv cov xwm txheej uas kov cov khoom tsis tuaj yeem ua tau. Cov ntsuas kub infrared yog luv thiab huv si siv txawm li cas los xij yuav tsis raug raws li cov thermocouples lossis RTDs hauv ob peb kis. Lawv tsis tu ncua siv rau qhov chaw ntsuas qhov kub thiab txias lossis hauv cov haujlwm uas qhov nrawm nrawm yog qhov tseem ceeb.
Thermistors yog cov khoom siv hluav taws xob semiconductor uas nws hloov kho nrog qhov kub thiab txias. Thermistors yog qhov kov heev thiab tuaj yeem muab kev txiav txim siab ntsuas kub ntau dhau. Txawm li cas los xij, lawv muaj qhov kub thiab txias ntau yam thiab yuav tsis zoo li RTDs lossis thermocouples. Thermistor yog siv tsis tu ncua hauv cov khoom siv hluav taws xob thiab ob peb qhov kev pab cuam kub. Hauv kev xaus, qhov txawv ntawm qhov ntsuas kub ntsuas gadgets zoo li thermocouples, RTDs, infrared thermometers, thiab thermistors muaj qhov zoo ntawm cov kab lus ntawm qhov kub thiab txias, qhov tseeb, ruaj khov, nqi, thiab kev ceeb toom haum. Kev nkag siab txog cov kev hloov pauv no tuaj yeem pab txiav txim siab txog cov cuab yeej tsim nyog rau qhov kev xav tau xaiv.
