Cov laj thawj tseem ceeb vim li cas cov hlau hluav taws xob txheem yuav tsis ua haujlwm

1. Kev Sib Piv ntawm Cov Khoom Siv
- Cov thermocouples yog ua los ntawm cov khub hlau tshwj xeeb (piv txwv li.Hom Ksiv Chromel thiab Alumel,Hom Jsiv Hlau thiab Constantan).
- Siv cov xov tooj liab ib txwm yuav cuam tshuam lub voj voog thermoelectric, ua rau nyeem tsis raug.
2. Kev Tiv Thaiv Kub
- Cov thermocouples feem ntau ua haujlwm hauv qhov kub thiab txias heev (txij li -200 ° C mus txog 2300 ° C, nyob ntawm hom).
- Cov xov hlau txheem yuav oxidize, degrade, lossis yaj nyob rau hauv qhov kub siab, ua rau lub teeb liab distortion lossis ua tsis tiav.
3. Kev Ncaj Ncees ntawm Lub Teeb Liab & Kev Tiv Thaiv Suab Nrov
- Cov teeb liab thermocouple nyob rau hauv qhov ntau millivolt, ua rau lawv yooj yim rau kev cuam tshuam electromagnetic (EMI).
- Cov xov hlau thermocouple zoo suav nrog kev tiv thaiv (piv txwv li, braided lossis foil shielding) kom tiv thaiv suab nrov los ntawm kev cuam tshuam cov nyeem ntawv.
4. Kev Ntsuas Qhov Tseeb
- Txhua hom thermocouple (J, K, T, E, thiab lwm yam) muaj ib qho kab voltage-kub uas tau teeb tsa tus qauv.
- Kev siv cov xov hlau tsis sib xws hloov pauv qhov kev sib raug zoo no, ua rau muaj qhov yuam kev calibration thiab cov ntaub ntawv tsis txhim khu kev qha.

Hom Thermocouple Hlau

Muaj ob pawg tseem ceeb ntawm cov hlau thermocouple:
1. Hlau txuas ntxiv
- Ua los ntawm cov hlau sib xyaw zoo ib yam li lub thermocouple nws tus kheej (piv txwv li, Hom K txuas ntxiv hlau siv Chromel thiab Alumel).
- Siv los txuas lub teeb liab thermocouple mus deb heev yam tsis muaj qhov yuam kev.
- Feem ntau siv rau hauv qhov chaw kub nruab nrab (vim tias kub heev tseem tuaj yeem cuam tshuam rau kev rwb thaiv tsev).
2. Kev them nyiaj hlau
- Ua los ntawm cov ntaub ntawv sib txawv tab sis zoo sib xws thermoelectrically (feem ntau pheej yig dua li cov thermocouple alloys ntshiab).
- Tsim los kom phim cov thermocouple qhov tso zis ntawm qhov kub qis dua (feem ntau qis dua 200 ° C).
- Feem ntau siv rau hauv cov vaj huam sib luag tswj thiab cov cuab yeej siv uas qhov kub heev tsis yog qhov tseem ceeb.
Ob hom yuav tsum ua raws li cov qauv kev lag luam (ANSI/ASTM, IEC) kom ntseeg tau tias muaj kev sib xws thiab kev ua tau zoo.

Xaiv Cov Hlau Thermocouple Zoo

Thaum xaiv cov xov hlau thermocouple, xav txog:
- Hom Thermocouple (K, J, T, E, thiab lwm yam) - Yuav tsum phim hom sensor.
- Qhov Kub thiab Txias - Xyuas kom tseeb tias cov hlau tuaj yeem ua haujlwm tau raws li qhov xav tau.
- Cov Khoom Siv Rwb Thaiv Tsev - Fiberglass, PTFE, lossis ceramic rwb thaiv tsev rau cov ntawv thov kub siab.
- Cov Kev Cai Tiv Thaiv - Braided lossis foil shielding rau EMI tiv thaiv hauv cov chaw ua haujlwm.
- Kev Ywj Pheej & Kev Ruaj Khov - Cov xov hlau khi rau cov khoov nruj, cov tub ntxhais khov kho rau kev teeb tsa ruaj khov.
