Mfundo ya vibrating string pressure sensor

Sensa yothamanga ya zingwe ndi kachipangizo kakang'ono kafupipafupi, muyeso wafupipafupiwu uli ndi kulondola kwakukulu,
chifukwa nthawi ndi mafupipafupi ndi magawo a thupi omwe angayesedwe molondola, ndipo chizindikiro chafupipafupi chikhoza kunyalanyazidwa mu njira yotumizira kukana kwa chingwe, inductance, capacitance ndi zina.
Panthawi imodzimodziyo, chojambulira chachitsulo chogwedeza chingwe chimakhalanso ndi mphamvu zotsutsana ndi kusokoneza, kusuntha kwazing'ono zero, kutentha kwabwino, mawonekedwe osavuta, kusamvana kwakukulu, ntchito yokhazikika, kufalitsa deta, kukonza ndi kusunga, kosavuta kuzindikira digito. chida, kotero kugwedera chingwe kuthamanga kachipangizo angagwiritsidwenso ntchito monga mmodzi wa mayendedwe a kuzindikira chitukuko luso.

Chinthu chodziwika bwino cha kugwedezeka kwa sensa ya waya ndi chingwe chachitsulo, ndipo ma frequency achilengedwe a chinthu chodziwika bwino amagwirizana ndi mphamvu yamphamvu.
Kutalika kwa chingwe kumakhazikitsidwa, ndipo kusintha kwa kugwedeza kwafupipafupi kwa chingwe kungagwiritsidwe ntchito kuyeza kukula kwa kugwedezeka, ndiko kuti, kulowetsako ndi chizindikiro cha mphamvu, ndipo zotsatira zake ndi chizindikiro chafupipafupi.Kunjenjemera waya mtundu kuthamanga kachipangizo lagawidwa magawo awiri, m'munsi chigawo chimodzi makamaka osakaniza zigawo zikuluzikulu tcheru.
Chigawo chapamwamba ndi chipolopolo cha aluminiyamu chomwe chili ndi module yamagetsi ndi terminal, yomwe imayikidwa muzipinda ziwiri zazing'ono kuti kulimba kwa chipinda cha module chamagetsi sichimakhudzidwa pamene waya.
Sensa yothamanga ya waya imatha kusankha mtundu waposachedwa komanso mtundu wamtundu wa frequency.Kugwedezeka kwa chingwe cholumikizira chingwe chikugwira ntchito, chingwe chogwedezeka ndi ma frequency a resonant chimapitirizabe kugwedezeka, pamene kupanikizika koyezera kumasintha, ma frequency adzasintha, chizindikiro chafupipafupi ichi kupyolera mu chosinthira chikhoza kusinthidwa kukhala chizindikiro cha 4 ~ 20mA.
