Ma switch a capacitive proximity atha kugwiritsidwa ntchito polumikizana kapena kuzindikiritsa pafupifupi chilichonse. Ndi LANBAO's capacitive proximity sensor, ogwiritsa ntchito amatha kusintha kukhudzika komanso kulowa m'mitsuko yopanda zitsulo kapena zotengera kuti azindikire zakumwa zamkati kapena zolimba.
01 Chidule chaukadaulo
Capacitor yomwe ili ndi mbale ziwiri imapanga malo amagetsi pakati pa mbale pamene ikugwiritsidwa ntchito. Chilichonse chomwe chimalowa m'munda uno chimasintha mphamvu pakati pa mbale.
Capacitor imathanso kukhala ndi mbale. Pankhaniyi, "mbale" yachiwiri ndi waya pansi.
Masensa onse a capacitive ali ndi zigawo zofanana.
1.Enclosures - Mawonekedwe osiyanasiyana, makulidwe ndi zida zamapangidwe
2.Basic sensor element - imasiyanasiyana malinga ndi ukadaulo wogwiritsidwa ntchito
3.Kuzungulira kwamagetsi - kuwunika zinthu zomwe zapezeka ndi masensa
4.Kulumikizana kwamagetsi - Kumapereka mphamvu ndi zizindikiro zotulutsa
Pankhani ya ma capacitive sensors, gawo lozindikira m'munsi ndi capacitor imodzi yokha ndipo kugwirizana kwa mbale kumakhazikika. Pamene chandamale chimasunthira kumalo ozindikira sensa, mphamvu ya capacitance imasintha ndikusintha kwa sensor.

3.Kulowetsa pamwamba
02 Zinthu zomwe zimakhudza kutalika kwa sensor
Mtunda wopangidwa umatanthawuza mtunda wakuthupi womwe umapangitsa kusintha kwa kusinthako kusintha pamene chandamale chikuyandikira malo opangidwa ndi sensa mu axial direction.
Tsamba lazogulitsa zathu limatchula mtunda atatu osiyanasiyana:
Mtundu wa Sensingamatanthauza mtunda wadzina womwe umafotokozedwa mu chitukuko, chomwe chimakhazikitsidwa pa chandamale cha kukula kwake ndi zinthu.
The Real Sensing Rangeamaganizira chigawo chopatuka kutentha firiji. Choyipa kwambiri ndi 90% yamitundu yodziwika bwino.
Distance Yeniyeni Yogwirira Ntchitoimaganizira za kusintha kwa malo komwe kumachitika chifukwa cha chinyezi, kukwera kwa kutentha ndi zinthu zina, ndipo choyipitsitsa kwambiri ndi 90% ya mtunda womwe umakhalapo. Ngati mtunda wa inductive ndi wofunikira, uwu ndiye mtunda woti mugwiritse ntchito.
Pochita, chinthucho sichikhala chofanana kukula ndi mawonekedwe. Chikoka cha kukula kwa chandamale chikuwonetsedwa pansipa:
Ngakhale zochepa kwambiri kuposa kusiyana kwa kukula ndi kusiyana kwa mawonekedwe. Chithunzi chomwe chili pansipa chikuwonetsa zotsatira za mawonekedwe a chandamale.
Ndizovuta kupereka chowongolera chotengera mawonekedwe, kotero kuyesa kumafunika pamapulogalamu omwe mtunda wa inductive ndi wofunikira.
Pomaliza, chinthu chachikulu chomwe chimakhudza mtunda wopangidwa ndi dielectric pafupipafupi chandamale. Kwa masensa a capacitive level, kukwezeka kwa dielectric pafupipafupi, ndikosavuta kuti zinthu zizindikire. Monga lamulo la chala chachikulu, ngati dielectric nthawi zonse ndi yayikulu kuposa 2, zinthuzo ziyenera kudziwika. Zotsatirazi ndi ma dielectric constants a zinthu zina wamba kuti angogwiritsa ntchito.
03 Capacitive sensor yozindikira mulingo
Kuti mugwiritse ntchito bwino ma capacitive sensors kuti muzindikire mulingo, onetsetsani kuti:
Makoma a chotengeracho si achitsulo
Kunenepa kwa khoma lachidebe kuchepera ¼" -½"
Palibe zitsulo pafupi ndi sensa
Malo olowetsamo amaikidwa mwachindunji pakhoma la chidebecho
Equipotential maziko a sensa ndi chidebe
