Thaum nws los txog rau qhov ntsuas, txhua tus yuav tsis xav tias tsis paub. Lawv ua tau zoo heev hauv kev ntsuas qhov hnyav hauv lub neej txhua hnub. Cov nplais feem ntau suav nrog cov nplai hauv chav ua noj, hluav taws xob lub cev nplai, thiab cov nplais lub cev. Yog li, dab tsi yog cov ntsiab lus tseem ceeb uas yuav tsum tau kuaj xyuas thiab cov kev xeem twg yuav tsum tau ua thaum kuaj cov khoom? Peb vam tias cov ntsiab lus no yuav pab tau koj!
Txoj cai ua haujlwm
Thaum ib yam khoom muab tso rau ntawm qhov ntsuas, lub siab yog siv rau lub sensor, uas deforms, ua rau muaj kev hloov pauv hauv impedance. Nyob rau tib lub sijhawm, qhov excitation voltage yog siv los hloov thiab tso tawm cov teeb liab simulated ntawm kev hloov. Lub teeb liab yog amplified los ntawm ib tug amplification Circuit Court thiab tso zis rau ib tug analog-rau-digital converter. Hloov mus rau hauv cov txheej txheem digital yooj yim thiab tso tawm rau CPU rau kev tswj hwm kev ua haujlwm. CPU tso tawm qhov tshwm sim no rau cov saib raws li cov lus txib thiab cov kev pab cuam. Kom txog thaum qhov tshwm sim no tshwm sim.
