Yuav ua li cas txiav txim siab qhov zoo ntawm lub pas dej piezoelectric nrog tus multimeter
Piezoelectric ceramics yog artificially synthesized piezoelectric cov ntaub ntawv. Thaum raug rau sab nraud siab, hluav taws xob cov nqi yog tsim rau ob qho chaw, nrog tus nqi them ncaj qha rau lub siab. Qhov tshwm sim no yog lub npe hu ua Piezoelectric nyhuv. Vim yog lawv cov nyhuv piezoelectric ceramic tuaj yeem tiv thaiv hauv qab sab nraud hluav taws xob teb, ua rau lawv haum rau siv raws li suab}}}}}}} compated ib yam.
Lub piezoelectric nyhuv ntawm piezoeltric kab ke tuaj yeem siv nrog ib tug muaj ntau yam kev txiav txim siab lawv ua haujlwm.
Ntawm no yog yuav sim lawv:
Txhuas tawm ob lub xov hlau los ntawm ob lub electrodes ntawm cov piezoelectric ceramic daim ntawv thiab muab cov ntawv tiaj tus rau ntawm ib lub rooj.
Txuas ob lub xaim rau ob qhov kev sim ntawm mottimeter, thiab teem ntau sib txuam rau qhov tsawg kawg nkaus tam sim no ntau yam.
Maj mam nias lub ceramic daim ntawv nrog lub lwv cov plaub hau ntawm tus xaum thiab saib xyuas lub zog ntawm lub zog ntawm lub qhov cub.
Yog hais tias pultimatatimeter poiner viav vias ho, cov ntawv ceramic yog lawm.
Yog tias tsis muaj qhov pom tau yooj yim, cov ntawv ceramic raug puas ntsoog.
