Capacitive chinzvimbo sensor

1.Capacitive chinzvimbo sensor chisiri-yekubika chinzvimbo sensor, iyo inowanzove nezvikamu zvitatu: nzvimbo yekuona, inodzivirira danda uye gogo. Ivo vanogona kuyera chinzvimbo chaicho chechinangwa, asi chinhu chete. Kana chinhu chakayerwa hachisi chekuita, zvichiri kubatsira kuyera kwaro kana density.

2.Kunyariswa chinhu chinofambisa, chiratidzo chekuburitsa hachina chekuita nezvinhu zvechinhu, nekuda kwekunetseka kwekudzikisira, vese mahekitori akafanana elekrode. Rudzi urwu rwe sensor runonyanya kushandiswa mu disk dhiraivha, Semiconductor tekinoroji uye yakakwirira-chaiyo maindasitiri kuyerwa, asi zvinoda kwazvo kurongeka kwakanyanya uye kuwanda kwekupedzisira. Kana ichishandiswa kuyera isiri-conders, chinzvimbo checomputive sensors zvinowanzoshandiswa kuona mavara, majasi uye kuyera ubvu hwepepa kana firimu.

3.Capapacitive chinzvimbo sensor yaishandiswa kuyera mutsara wekuturika kure, kubva pamamirimita akati wandei kune akati wandei nanometers, uye kuyerwa kwakapera pakushandisa maitiro emagetsi ekusaita. Iko kugona kwechinhu kuchitoro chinonzi chinonzi cacacitance. ANOTOR CAPACITE DIKLE YOKUDZIDZA KUCHINESA ICHI PLATE CAPACE. Kugona kweiyo Plate Capacitor kwakananga zvakananga kune iyo electrode nharaunda uye dielectric nguva dzose, uye zvakazara chikamu kusvika kure pakati pefalekitori. Naizvozvo, kana chinhambwe pakati pemamwe ma electrodes achinja, kugona kuchinja zvakare. Mune izwi, chinzvimbo chekema sensor chinoshandisa hunhu uhu kuti upedze chinzvimbo chinzvimbo.

1 Imwe electrode yeiyo sensor iplate yesimbi, uye imwe yeElectrode yeCapacititor inoumbwa nechinhu chinoda kuitwa. Kana voltage isishandiswe pakati pemapuranga e condukitori, munda wemagetsi unosimbiswa pakati pemapuranga, uye mahwendefa maviri akachengetedza mhosva dzakanaka uye zvakashata zvakashata zvakazara. Capcitive chinzvimbo sensor kazhinji inogamuchira ac voltage, iyo inoita kuti mutero papepa rekuchinja nguva dzose, saka shanduko yenzvimbo yekutarisa inogona kuongororwa nekuyera kugona pakati pemaplate maviri.

5.Kugona kutemwa nehurefu pakati pemapurati, iyo dielectric inogara ichidya iyo dielectric uye chinhambwe pakati pemaplate. Mune vazhinji sensors, nharaunda uye dielectric inogara ichishanduka pabhesi reElectrode haizoshanduke, chinhambwe chete chinokanganisa kugona pakati pealectrode uye chinhu chakanangwa. Naizvozvo, shanduko yeaccount inogona kuratidza iyo chinangwa chinzvimbo. Kuburikidza neCalibration, iyo yekuburitsa voltage chiratidzo che sensor ine mutsara wehukama nehukama pakati pekuonekwa kwebhodhi uye chinangwa. Uku ndiko kunzwira tsitsi kwe sensor. Iyo inoratidza iyo chiyero chekuburitsa voltage shanduko kune chinzvimbo chekuchinja. Iyo yuniti inowanzo kanumbowo 1V / micron, iyo, iyo yekuburitsa voltage shanduko 1V yega yega macors.

6.Vaisiri voltage yashandiswa kunzvimbo yekuona, munda wemagetsi wakasiyana uchagadzirwa pane yakaonekwa chinhu. Kuti uderedze kupindira, denderedzwa rinodzivirira rinowedzerwa. Inoshandisa iwo mamwe maitiro emagetsi emigumo emagumo emagetsi ekuona kuti idzivirire munda wemagetsi munzvimbo yekuona kubva kuClowing. Vafambisi vezvimwe nzvimbo dzekucherekedza vanogadzira munda wemagetsi neyemagetsi emagetsi uye haazopindire nemunda wemagetsi pakati pechinangwa uye nzvimbo yekuona. Nekuda kweiyo nzvimbo yekudzivirira, iyo emagetsi munda munzvimbo yekuona ndeye conical. Iyo nzvimbo yakafungidzirwa yemunda yemagetsi yakapihwa neyekuongororwa Electrode ndeye 30% yakakura kupfuura nzvimbo yekuona. Naizvozvo, iyo nzvimbo yedhisheni yechinhu chakaonekwa chinofanira kunge chingangoita 30% yakakura kupfuura nzvimbo yekuona yeiyo sensor.
