Yuav ua li cas txiav txim siab seb puas muaj cov nyhuv siv hluav taws xob xav tau calibration?
Oct 10, 2025| 1. Saib xyuas qhov ruaj khov ntawm cov paib kos npe.
Yog hais tias lub sensor cov paib tawm tsam tsis ruaj khov (piv txwv li, sib quas ntus lossis hloov kho ntau), ntsuas hluav taws xob yuav tsim nyog.
Siv ib qho oscilloscope kom saib cov teeb liab WaveForm. Yog tias cov nthwv hluav taws xob yog qhov txawv txav (piv txwv li, distorted lossis amplitude tsis raug), ntsuas hluav taws xob.
2. Ntsuas lub hwj huam muab voltage.
Siv lub zog loj los tshawb xyuas lub sensor lub zog hluav taws xob voltage. Yog tias nws tsis yog nyob rau hauv cov kev teev tseg (piv txwv li, 5V lossis 12V), hluav taws xob muaj zog xav tau kev hloov kho lossis ntsuas kom haum.
3. Kev soj ntsuam ua haujlwm.
Hlau Khoom Noj Qhov Kev Ntsuas Ntaus: Tom qab tshem lub sensor, nqa cov khoom siv hlau kom ze rau nws lub taub hau thiab ntsuas qhov hluav taws xob ntawm cov teeb liab. Yog tias hloov pauv ntawm 0V rau 5V (lossis tus nqi sib haum rau 12v fais fab mov) thaum cov khoom hlau yog kaw, txoj haujlwm yog qhov qub; Txwv tsis pub, ntsuas hluav taws xob lossis hloov chaw yog xav tau.
Kev ntsuas ntau: Siv cov teeb tsa Diode los ntsuas cov pins. Yog tias ib txwm voltage poob (piv txwv li, 1.7v lossis 0.5v) tsis tuaj yeem ntsuas, ntsuas hluav taws xob lossis hloov hluav taws xob.
4. Piv nrog tus qauv tseem ceeb.
Sib piv cov sensor nrog cov cuab yeej paub zoo. Yog hais tias ntsuas ntsuas tau rhuav tshem qhov ntau (piv txwv li, tam sim no lossis txoj haujlwm nrhiav yuam kev), ntsuas hluav taws xob.
5. Ib puag ncig kev cuam tshuam.
Yog hais tias lub sensor ua haujlwm nyob rau hauv lub zog sib nqus lossis siab -}}} kev ua kom muaj kev cuam tshuam lossis kev tiv thaiv kev ntsuas lossis kev tiv thaiv los ntawm qhov cuam tshuam los yog kev thaiv ntawm qhov cuam tshuam.
Calibration cov tswv yim:
Calibration yuav tsum ua raws cov qauv hauv ntiaj teb (xws li IEE cov qauv), siv cov qauv kev sim lossis sib nqus.
Rau siab - precision cov kev xav tau, kev ntsuas calimration xws li kev sib nqus resonance resonance yuav raug txiav txim siab.
