Ukutshintsha kweCapacitive proximity kungasetyenziselwa ukudibana okanye ukubonwa okungaqhagamshelwanga phantse nayiphi na into. Nge-LANBAO's capacitive proximity sensor, abasebenzisi banokunyenyisa ubuntununtunu kwaye bangene kwiitoti ezingezizo ezentsimbi okanye izikhongozeli zokubona ulwelo lwangaphakathi okanye izinto eziqinileyo.
01 Isishwankathelo sobuGcisa
I-capacitor equkethe iipleyiti ezimbini ivelisa indawo yombane phakathi kwamacwecwe xa inikwe amandla. Nayiphi na impahla engena kule ntsimi itshintsha i-capacitance phakathi kwamacwecwe.
I-capacitor isenokuba nepleyiti. Kule meko, "ipleyiti" yesibini yintambo yomhlaba.
Zonke ii-capacitive sensors zineenxalenye ezisisiseko ezifanayo.
1.Ii-Enclosures - Iimilo ezahlukeneyo, ubukhulu kunye nezixhobo zokwakha
I-2.Basic sensor element - iyahluka ngokobuchwephesha obusetyenzisiweyo
3.Isekethe ye-elektroniki - ivavanya izinto ezifunyenwe ngamava
I-4.Uxhumo lombane - Inika amandla kunye neempawu zemveliso
Kwimeko ye-capacitive sensors, isiseko se-sensing element yi-capacitor yebhodi enye kunye nolunye udibaniso lweplate lusekelwe. Xa ithagethi ihambela kwindawo yokubona inzwa, ixabiso le-capacitance litshintsha kunye ne-sensor output switch.

02 Izinto ezichaphazela umgama wokuva wenzwa
Umgama owenziweyo ubhekiselele kumgama womzimba obangela ukuba ukutshintshwa kwesiphumo sitshintshe xa i-target isondela kwi-sensor induced surface kwi-axial direction.
Iphepha leparameter yemveliso yethu lidwelisa imigama emithathu eyahlukeneyo:
Uluhlu loVavanyoibhekisa kumgama oqingqiweyo ochazwe kwinkqubo yophuhliso, esekelwe kwithagethi yobungakanani obuqhelekileyo kunye nezinto eziphathekayo.
Uluhlu Lokwenyani Lweemvakaleloithathela ingqalelo ukutenxa kwinqanaba lobushushu begumbi. Eyona meko imbi kakhulu yi-90% yoluhlu lokuva okuqhelekileyo.
Owona Mgama wokuSebenzaithathela ingqalelo i-switch point drift ebangelwa kukufuma, ukunyuka kwamaqondo obushushu kunye nezinye izinto, kwaye eyona meko imbi kakhulu yi-90% yowona mgama owenziweyo. Ukuba umgama we-inductive ubalulekile, lo ngumgama oza kuwusebenzisa.
Ngokwesiqhelo, into ayifane ibe nobungakanani obuqhelekileyo kunye nemilo. Impembelelo yobukhulu ekujoliswe kuyo iboniswe ngezantsi:
Nokuba okungaphantsi kwesiqhelo kunomahluko wobungakanani ngumahluko wokumila. Lo mzobo ungezantsi ubonisa umphumo wemilo ekujoliswe kuyo.
Kunzima ngokwenene ukubonelela ngemeko yolungiso olusekwe kwimilo, ngoko ke uvavanyo luyafuneka kwizicelo apho umgama wokufundisa ubalulekile.
Ekugqibeleni, eyona nto iphambili echaphazela umgama owenziweyo yi-dielectric constant yethagethi. Kwi-capacitive level sensors, ukuphakama kwe-dielectric constant, kulula ukufumanisa izinto eziphathekayo. Njengomgaqo jikelele wesithupha, ukuba i-dielectric constant ingaphezulu kwe-2, izinto eziphathekayo kufuneka zibonwe. Oku kulandelayo zii-dielectric constants zezinye izinto eziqhelekileyo zokubhekisela kuphela.
03 Isivamvo esinamandla sokubona inqanaba
Ukuze usebenzise ngempumelelo i-capacitive sensors zokubona inqanaba, qinisekisa ukuba:
Iindonga zenqanawa aziyi-metallic
Ubukhulu bodonga lwesikhongozeli ngaphantsi kwe ¼" -½"
Akukho ntsimbi kufutshane nenzwa
Umphezulu we-induction ubekwe ngokuthe ngqo eludongeni lwesitya
I-equipotential grounding ye-sensor kunye ne-container
