1.ihame ryimikorere

Ihame ryakazi ryo kurwanya ibyuma byerekana ibipimo ni ibintu byerekana ko imbaraga zo kurwanya imbaraga zandikiwe ku bintu fatizo bihinduka hamwe no guhindura imashini, bikunze kwitwa ingaruka zo guhangana.Agaciro ko guhangana nicyuma gishobora kugaragazwa nuburyo bukurikira:

R = ρ

Aho: ρ-irwanya imiyoboro yicyuma (ω / m)

S—— Agace kambukiranya agace kayobora ()

Uburebure bwa L (m)

Reka dufate urugero rwo kurwanya insinga z'icyuma nk'urugero.Iyo insinga yicyuma ikorewe imbaraga ziva hanze, uburebure bwayo nubutaka bwambukiranya bizahinduka.Duhereye kuri formula yavuzwe haruguru, birashobora kugaragara byoroshye ko agaciro kayo ko guhangana kazahinduka.Niba insinga y'icyuma irambuwe n'imbaraga zo hanze, uburebure bwayo buziyongera kandi agace kambukiranya ibice bizagabanuka, kandi agaciro kayo ko kurwanya.Iyo insinga ihagaritswe n'imbaraga zo hanze, uburebure buragabanuka kandi igice cyambukiranya kikiyongera, kandi agaciro ko kurwanya kugabanuka.Igihe cyose hapimwe impinduka zurwanya (mubisanzwe voltage hejuru yurwanya irapimwa), ikibazo cyurugero rwinsinga zirashobora kuboneka.

Gushyira mu bikorwa

Umuyoboro wa ceramic wihanganira ruswa ntushobora kwanduza amazi, kandi umuvuduko ukora muburyo butaziguye hejuru yimbere ya diafragma ceramic, bigatuma diafragma ihinduka gato.Kurwanya firime ndende byacapwe hejuru yinyuma ya ceramic diaphragm hanyuma bigahuzwa kugirango bibe ikiraro cya Wheatstone (ikiraro gifunze).Bitewe n'ingaruka za piezoresistive ya piezoresistor, ikiraro gitanga ibimenyetso byumurongo wa voltage cyane ugereranije numuvuduko kandi bikagereranywa na voltage ishimishije.Ikimenyetso gisanzwe gihindurwa nka 2.0 / 3.0 / 3.3 mV / V ukurikije umuvuduko utandukanye.Binyuze muri kalibrasi ya laser, sensor ifite ubushyuhe bwo hejuru hamwe nigihe gihamye.Rukuruzi ifite ubushyuhe bwayo bwa 0 ~ 70 ℃ kandi irashobora guhura neza nibitangazamakuru byinshi.

Ceramic ni ibintu bizwi kandi byoroshye, birwanya ruswa, birwanya kwambara, birwanya ingaruka hamwe no kunyeganyega.Ubushyuhe bwumuriro bwibumba nubukonje bwa firime burashobora gutuma ubushyuhe bwakazi bukora kugeza kuri 40 ~ 135 and, kandi bifite ubunyangamugayo buhamye kandi buhamye mubipimo.Impamyabumenyi y'amashanyarazi> 2kV, ibimenyetso bisohoka bikomeye kandi bihamye igihe kirekire.Ibyuma bya Ceramic bifite ibimenyetso biranga nibiciro biri hasi bizaba icyerekezo cyiterambere cyumuvuduko.Mu Burayi no muri Amerika, hari inzira yo gusimbuza burundu ubundi bwoko bwa sensor.Mubushinwa, abakoresha benshi kandi benshi bakoresha ibyuma bya ceramic kugirango basimbuze ibyuma bya silikoni ikwirakwizwa.
