Kodi cell cell ndi chiyani?
Dongosolo la mlatho wa Wheatstone (lomwe limagwiritsidwa ntchito kuyeza kupsyinjika pamwamba pa chinthu chothandizira) lidasinthidwa ndikutchuka ndi Sir Charles Wheatstone mu 1843 ndi lodziwika bwino, koma mafilimu opyapyala omwe adayikidwa mudera lakale lomwe layesedwa komanso loyesedwa Kugwiritsa ntchito sikumveka bwino. pa. Njira zowonetsera mafilimu ocheperako si zachilendo kumakampani. Njirayi imagwiritsidwa ntchito pazinthu zambiri, kuyambira pakupanga ma microprocessors ovuta kupanga ma resistor olondola a ma gage ovuta. Kwa ma gage oponderezana, ma gage amafilimu ocheperako omwe amatsatiridwa molunjika pagawo lopanikizika ndi njira yomwe imachotsa zovuta zambiri zomwe zimakumana ndi "magalasi ophatikizika" (omwe amadziwikanso kuti ma gage a foil, ma gage osasunthika, ndi ma geji a silicon).
Kodi chitetezo chochulukira cha cell cholemetsa chimatanthauza chiyani?
Selo iliyonse yonyamula katundu idapangidwa kuti izisokoneza pansi pa katundu molamulidwa. Akatswiri amawongolera kupotoza uku kuti kukulitsa chidwi cha sensa ndikuwonetsetsa kuti kapangidwe kake kamagwira ntchito m'dera lake "elastic". Katunduyo akachotsedwa, kapangidwe kachitsulo kamene kamasokonekera ndi dera lake lotanuka, kamabwerera ku chiyambi chake. Zomangamanga zomwe zimadutsa dera lotanukali zimatchedwa "zodzaza". Sensa yodzaza ndi "pulasitiki yosinthika," momwe kapangidwe kake kamasokonekera, osabwereranso ku chikhalidwe chake choyambirira. Ikasinthidwa pulasitiki, sensayo siperekanso mzere wofanana ndi katundu womwe wagwiritsidwa ntchito. Nthawi zambiri zimakhala zowonongeka komanso zosasinthika. "Overload Protection" ndi kapangidwe kamene kamapangitsa kuti sensa ikhale yocheperako pang'onopang'ono m'munsi mwa malire ake olemetsa, potero imateteza sensa ku katundu wosayembekezeka kapena wosunthika womwe ungayambitse kupunduka kwa pulasitiki.
Momwe mungadziwire kulondola kwa cell cell?
Kulondola kwa sensa kumayesedwa pogwiritsa ntchito magawo osiyanasiyana ogwiritsira ntchito. Mwachitsanzo, ngati sensa yanyamula katundu wake wochuluka, ndiyeno katunduyo amachotsedwa, mphamvu ya sensa yobwereranso kumalo omwewo omwe ali ndi zero pazochitika zonsezi ndi muyeso wa "hysteresis". Magawo ena akuphatikiza Nonlinearity, Repeatability, ndi Creep. Iliyonse mwa magawowa ndi yapadera ndipo ili ndi zolakwika zake. Timalemba magawo onsewa mu datasheet. Kuti mumve zambiri zaukadaulo wamawu awa, chonde onani glossary yathu.
Kodi muli ndi njira zina zotulutsira ma cell anu onyamula katundu ndi masensa opanikizika pambali pa mV?
Inde, ma board opangira ma siginecha a alumali akupezeka ndi mphamvu mpaka 24 VDC ndipo mitundu itatu ya zosankha zilipo: 4 mpaka 20 mA, 0.5 mpaka 4.5 VDC kapena I2C digito. Nthawi zonse timapereka ma board ogulitsidwa ndipo amasinthidwa kukhala max load sensor. Mayankho achikhalidwe amatha kupangidwa pa protocol ina iliyonse.
