Tom qab calibration, qhov tseeb ntawm qhov txias junction them module yuav tsum tau xyuas los ntawm kev sib piv benchmark, multi-channel sib xws, ntev -lub sij hawm stability, thiab dynamic teb kev ntsuam xyuas kom paub meej tias qhov system kub ntsuas qhov yuam kev yog tswj nyob rau hauv ± 1℃.
1. Kev Txheeb Xyuas Qhov Chaw Sib Piv (Core Method)
Muab cov thermocouple kub hlws ris thiab tus qauv platinum tiv thaiv tus pas ntsuas kub (piv txwv li, PT100) sab -los ntawm- sab hauv da dej kub tas li, thiab sib piv cov kev nyeem ntawm qhov ntsuas kub tseem ceeb xws li 0℃(qhib da dej), 25℃, 100℃, thiab 300℃.
Qhov sib txawv ntawm tus qauv qhia tus nqi thiab tus qauv tus nqi yuav tsum tsawg dua lossis sib npaug li ± 1 degree, qhov zoo tshaj tsis tshaj ± 0.5 degree.
High- cov cuab yeej siv tau raug pom zoo raws li qhov ntsuas ntsuas: FLUKE 71830 qhov chaw kub thiab txias los yog ConST326 ntse calibrator.
Piv txwv li: Hauv 100.0℃roj da dej, yog tias qhov kev nyeem ntawv module yog 100.3 degree, qhov sib txawv ntawm +0.3℃yog nyob rau hauv qhov kev pom zoo.
2. Multi-channel Consistency Verification: Txuas ntau lub thermocouples ntawm tib hom nyob rau hauv tib qhov kub thiab txias ib puag ncig thiab soj ntsuam qhov sib txawv ntawm kev nyeem ntawv thoob plaws.
Tso cai sib txawv<0.8°C; if individual channels show significant drift, check for loose wiring or module malfunction.
Nyob rau hauv qhov kub thiab av noo ib puag ncig ntawm Wuhan, nws raug nquahu kom kuaj xyuas oxidation ntawm cov hlau txuas, uas yuav cuam tshuam rau kev sib cuag.
3. Ntev-Lub Sijhawm Ua Haujlwm Kev Ruaj Ntseg: Ua haujlwm tsis tu ncua rau 8-24 teev nyob rau hauv qhov kub thiab txias tsis tu ncua thiab kaw qhov kub hloov pauv.
Cov txheej txheem dhau los: Tsis muaj kev nruam txuas ntxiv (piv txwv li, siab dua ± 2 degree), tsis muaj kev dhia ib ntus lossis qib - zoo li kev hloov pauv.
Cov ntaub ntawv keeb kwm tuaj yeem raug xa tawm siv lub tshuab computer software los txheeb xyuas qhov sib luag.
4. Dynamic Response thiab Anti-Interference Capability Test:
Kev cuam tshuam ntawm kev sib tshuam txias: Kub lub module casing los ntawm txhais tes los yog txias nws nrog ib tug kiv cua thiab saib seb cov nyiaj them system yuav sai sai kho rau lag.
Electromagnetic compatibility test: Khiav lub module nyob ze qhov chaw muaj zog cuam tshuam xws li zaus converters thiab motors thiab xyuas cov ntaub ntawv hloov pauv. Nws raug nquahu kom siv cov hlau thaiv kev tiv thaiv thiab xyuas kom muaj kev ruaj ntseg hauv av.
5. Software Diagnostics thiab Log Traceability
High-end modules (xws li Husky Altanium™) txhawb nqa tiag tiag- lub sijhawm tso saib ntawm qhov tsis xws li qhov kub thiab txias qhov hluav taws xob thiab cov nyiaj them poob haujlwm, thiab cov ntawv teev tuaj yeem xa tawm mus rau kev tshuaj xyuas ntawm lub tshuab computer.
Xyuas kom tseeb tias cov ntaub ntawv calibration tsis ntev los no yog nyob rau hauv 6 lub hlis dhau los los xyuas kom meej traceability.
Thaum siv cov qauv zoo li MAX31855 / MAX6675, qhov kub ntawm qhov sib txuas sab hauv tuaj yeem nyeem tau ntawm SPI interface los txheeb xyuas nws qhov sib xws nrog ntsuas qhov ntsuas kub.
Tswv yim pom zoo: Ua ntej thawj zaug khiav tom qab calibration, ua tiav tus kheej - kuaj kom paub meej tias kev sib txuas lus ib txwm thiab tsis muaj lub tswb los ntawm SF lub teeb.
