Maswichi ekudzivirira kuswedera pedyo anogona kushandiswa kuona chero chinhu chinenge chakabatana kana chisina kubatana. Nekushandisa sensor yeLANBAO's capacitive proximity, vashandisi vanogona kugadzirisa kunzwisisika uye kutopinda mumagaba kana mumidziyo isiri yesimbi kuti vaone mvura kana zvinhu zvakasimba zviri mukati.
01 Ongororo yeUnyanzvi
Capacitor ine maplate maviri inogadzira munda wemagetsi pakati pemaplate kana ichishandiswa. Chero chinhu chinopinda mumunda uyu chinoshandura simba riri pakati pemaplate.
Capacitor inogonawo kunge iine ndiro. Muchiitiko ichi, "ndiro" yechipiri iwaya yepasi.
Masensa ese e capacitive ane zvikamu zvakafanana zvekutanga.
1. Makomba - Maumbirwo akasiyana-siyana, saizi uye zvinhu zvekuvaka
2. Chinhu cheBasic sensor - chinosiyana zvichienderana netekinoroji inoshandiswa
3. Electronic circuit - inoongorora zvinhu zvakaonekwa nemasensa
4. Kubatana kwemagetsi - Kunopa masaini emagetsi uye emagetsi anobuda
Kana iri capacitive sensors, base sensing element ibhodhi rimwe chete capacitor uye imwe plate connection inenge yakamira. Kana chinangwa chikafamba kuenda kunzvimbo yekuona sensor, capacitance value inochinja uye sensor output switches.

02 Zvinhu zvinokanganisa daro rekunzwa kwesensor
Distance inokonzerwa inoreva daro remuviri rinoita kuti switch output ichinje kana chinangwa chasvika pamusoro pe sensor inokonzerwa ne sensor munzira ye axial.
Pepa rema parameter echigadzirwa chedu rinoratidza madaro matatu akasiyana:
Rudzi rweKunzwazvinoreva daro rezita rinotsanangurwa mukugadzirwa, iro rakavakirwa pachinangwa chehukuru hwakajairika nezvinhu.
Rudzi Rwechokwadi rweKunzwainofunga nezvekutsauka kwezvikamu patembiricha yemumba. Nyaya yakaipa zvikuru ndeye 90% yenzvimbo yekunzwa kwemazita.
Kureba Chaiko Kwekushandainoongorora kusvetuka kwenzvimbo yekuchinja kunokonzerwa nehunyoro, kukwira kwetembiricha nezvimwe zvinhu, uye nyaya yakaipisisa ndeye 90% yedaro chairo rinokonzerwa. Kana daro reinductive riri rakakosha, iri ndiro daro rekushandisa.
Mukuita, chinhu chacho hachiwanzo kuva nehukuru nechimiro zvakajairwa. Simba rehukuru hwechinangwa rinoratidzwa pazasi:
Musiyano wechimiro hauwanzoitiki pane musiyano wehukuru. Mufananidzo uri pazasi unoratidza mhedzisiro yechimiro chechinhu chauri kuda.
Zvakaoma kupa chinhu chinogadzirisa chimiro, saka kuyedza kunodiwa mumashandisirwo azvo uko daro remuchina wekuongorora (inductive distance) rakakosha.
Chekupedzisira, chinhu chikuru chinokanganisa daro rinokonzerwa idielectric constant yechinangwa. Kune masensa e capacitive level, dielectric constant yakakwira, zviri nyore kuona chinhu chacho. Semutemo wenguva dzose, kana dielectric constant yakakura kupfuura 2, chinhu chacho chinofanira kuonekwa. Izvi zvinotevera ma dielectric constant ezvimwe zvinhu zvakajairika zvekutarisa chete.
03 Sensor yekuona nhanho
Kuti ushandise zvinobudirira ma capacitive sensors pakuona level, iva nechokwadi chekuti:
Madziro echikepe haasi esimbi
Ukobvu hwemadziro emudziyo husingasviki ¼" -½"
Hapana simbi iri pedyo ne sensor
Nzvimbo yekupinza inoiswa zvakananga pamadziro emudziyo
Kuisa pasi kwesensa nechirongo mumidziyo
