Calibrating ib tug thermocouple txias junction compensator feem ntau yuav siv sij hawm 1.5 mus rau 3 teev, nyob ntawm seb tus naj npawb ntawm calibration cov ntsiab lus, hom khoom, thiab tus neeg teb xov tooj txawj. Rau tus qauv 5-point calibration (xws li, 20 degree, 25 degree, 30 degree, 40 degree, 50 degree), tus kws tshaj lij tuaj yeem ua tiav nws li ntawm 90 feeb hauv ib puag ncig tus qauv; suav nrog kev npaj, sau cov ntaub ntawv, thiab cov ntawv tshaj tawm, lub sijhawm tag nrho yog kwv yees li 2.5 teev.
I. Calibration Lub Sijhawm Kev Ua Haujlwm (Ua phau ntawv ntau-Point Comparison Method ua piv txwv)

Kev siv sijhawm |
Kev piav qhia |
|
1. Kev npaj ua ntej |
20-30 feeb |
Xws li kev hloov pauv ntawm ib puag ncig kub thiab av noo, cov khoom siv ua ntej cua sov (30 feeb rau kev them nyiaj lub zog-rau), tus qauv tus kheej- kuaj, kuaj kab, thiab lwm yam. |
|
2. Cold Junction Reference Point Calibration (0 degree) |
15-20 feeb |
Siv lub ntsuas dej khov nab kuab los tsim kom muaj 0℃siv taw tes thiab txheeb xyuas qhov tseeb ntawm qhov pib them nyiaj. Tos kom qhov kub thiab txias kom ruaj khov thiab nyeem ntawv. |
|
3. Multi-Tub kub Point Dynamic Calibration |
60-90 feeb |
Txhua qhov ntsuas kub yuav tsum tau teeb tsa, tswj qhov kub thiab txias (10-15 feeb / taw tes), ntsuas, thiab kaw. Tag nrho lub sij hawm rau 5 ntsiab lus yog lub ntsiab theem. |
|
4. Kev tsim cov ntaub ntawv thiab tshaj tawm |
20-30 feeb |
Xam qhov sib txawv, txiav txim siab ua raws, sau cov ntawv qhia txog kev ntsuas, cov ntawv sau, thiab cov ntaub ntawv khaws tseg. |
✅ Lub tswv yim: Yog tias siv lub tshuab ntsuas hluav taws xob tsis siv neeg (xws li lub tshuab hluav taws xob ntse txhawb Modbus kev sib txuas lus), lub sijhawm tuaj yeem ua kom luv dua li 60 feeb, vim qhov ntsuas kub thiab ntsuas cov ntaub ntawv tuaj yeem ua tiav tiav.
II. Yam tseem ceeb cuam tshuam rau lub sijhawm Calibration
Khoom siv:
Analog Choj Compensator: Yuav tsum tau hloov kho potentiometer, ua rau lub sij hawm calibration ntev dua.
Digital Intelligent Compensator: Txhawb tsis siv neeg scanning thiab parameter sau, muab kev ua tau zoo dua.
Number of Calibration Points:
Feem ntau, kev lag luam- qib calibration siv 3-5 ntsiab lus.
High -precision metrology- qib calibration tuaj yeem txuas ntxiv mus rau 7 lossis ntau dua cov ntsiab lus, nce lub sijhawm ntau dua 30%.
Environmental Stability: Qhov kub thiab txias hloov pauv ua kom ntev qhov kub thiab txias -tswj lub sijhawm tos. Hauv Wuhan qhov siab - qhov kub thiab txias ib puag ncig lub caij ntuj sov, txhim kho huab cua txias tswj yog tsim nyog.
Kev Paub Txog Tus Neeg Ua Haujlwm: Cov neeg ua haujlwm tshiab tuaj yeem ua rau rov ntsuas dua vim kev xaim tsis raug lossis kev nyeem ntawv yuam kev, ncua sijhawm tag nrho lub sijhawm ntsuas.
