Isivamvo sesikhundla esinamandla

I-1.Capacitive position sensor is a non-contact position position, ehlala iqulethwe ngamacandelo amathathu: indawo yokufumanisa, umgca wokukhusela kunye negobolondo. Banokulinganisa indawo ngqo ekujoliswe kuyo, kodwa kuphela into. Ukuba into elinganisiweyo ayiqhubeki, kuseluncedo ukulinganisa ubukhulu okanye ubuninzi bayo.

2.Xa ulinganisa into eqhubayo, isignali yokuphuma ayinanto yakwenza nezinto zento, kuba i-capacitive displacement sensor, zonke ii-conductor ziyi-electrode efanayo. Olu hlobo lwenzwa lusetyenziswa kakhulu kwi-disk drive, itekhnoloji ye-semiconductor kunye nomlinganiselo ochanekileyo weshishini, kodwa ifuna ukuchaneka okuphezulu kakhulu kunye nokuphendula rhoqo. Xa isetyenziselwa ukulinganisa i-non-conductors, i-capacitive position sensors idla ngokusetyenziselwa ukufumanisa iilebula, iingubo kunye nokulinganisa ubukhulu bephepha okanye ifilimu.

I-3.Capacitive position sensor ekuqaleni yayisetyenziselwa ukulinganisa umgama wokufuduka komgca, ukusuka kwiimilimitha ezininzi ukuya kwii-nanometers ezininzi, kwaye umlinganiselo wagqitywa ngokusebenzisa iimpawu zombane ze-conductivity. Ukukwazi kwento ukugcina intlawulo kubizwa ngokuba yi-capacitance. Isixhobo esiqhelekileyo se-capacitor yokugcina intlawulo yi-plate capacitor. I-capacitance ye-plate capacitor ihambelana ngokuthe ngqo kwindawo ye-electrode kunye ne-dielectric constant, kunye ne-inversely proportional kumgama phakathi kwe-electrode. Ngoko ke, xa umgama phakathi kwee-electrodes utshintsha, i-capacitance nayo iyatshintsha. Ngegama, i-capacitive position sensor isebenzisa olu phawu ukugqibezela ubhaqo lwendawo.

I-4.I-sensor ye-capacitive isikhundla esiqhelekileyo iquka i-electrode ezimbini zetsimbi, ezinomoya njenge-dielectric. Enye i-electrode ye-sensor yintsimbi yensimbi, kwaye enye i-electrode ye-capacitor yenziwe yinto eqhubayo ukuba ibonwe. Xa i-voltage isetyenziswe phakathi kwamacwecwe e-conductor, intsimi yombane isekwe phakathi kwamacwecwe, kwaye iiplati ezimbini zigcina iintlawulo ezintle kunye neentlawulo ezimbi ngokulandelanayo. I-sensor ye-Capacitive position idla ngokuthatha i-voltage ye-AC, eyenza intlawulo kwi-plate itshintshe i-polarity rhoqo, ngoko ke utshintsho lwendawo ekujoliswe kuyo lunokubonwa ngokulinganisa i-capacitance phakathi kwamacwecwe amabini.

I-5.I-capacitance inqunywe ngumgama phakathi kwamacwecwe, i-dielectric constant ye-dielectric kunye nomgama phakathi kwamacwecwe. Kwiinzwa ezininzi, indawo kunye ne-dielectric constant ye-electrode plate ayiyi kutshintsha, kuphela umgama uya kuchaphazela i-capacitance phakathi kwe-electrode kunye nento ekujoliswe kuyo. Ngoko ke, utshintsho lwamandla lungabonisa indawo ekujoliswe kuyo. Ngokusebenzisa ukulinganisa, umqondiso we-voltage ophumayo we-sensor unobudlelwane bomgca kunye nomgama phakathi kwebhodi yokufumanisa kunye nokujoliswe kuyo. Olu luvakalelo loluvo. Ibonisa umlinganiselo wokutshintsha kombane ophumayo kutshintsho lwendawo. Iyunithi idla ngokuba yi-1V/micron, oko kukuthi, i-voltage ephumayo itshintsha i-1V nganye kwi-100 microns.

6.Xa i-voltage isetyenziswe kwindawo yokufumanisa, indawo yombane edibeneyo iya kuveliswa kwinto efunyenweyo. Ukuze kuncitshiswe ukuphazamiseka, umgca wokukhusela uyongezwa. Isebenzisa amandla afanayo e-electromotive kuzo zombini iziphelo zendawo yokukhangela ukukhusela intsimi yombane kwindawo yokukhangela ukuba ingavuzi. Abaqhubi abangaphandle kwezinye iindawo zokufumanisa baya kwenza intsimi yombane kunye noluhlu olukhuselayo kwaye aluyi kuphazamisa indawo yombane phakathi kokujoliswe kuyo kunye nommandla wokufumanisa. Ngenxa yoluhlu olukhuselayo, intsimi yombane kwindawo yokufumanisa i-conical. Ummandla ocetywayo wommandla wombane okhutshwe yi-electrode yokufumanisa i-30% enkulu kunommandla wokufumanisa. Ngoko ke, indawo yobubanzi bento efunyenweyo kufuneka ibe ubuncinane i-30% enkulu kunommandla wokubona inzwa.
