Izitshixi zokufikelela kwi-capacitive zingasetyenziselwa ukufumanisa phantse nayiphi na into edibanayo okanye engeyiyo edibanayo. Nge-LANBAO's capacitive proximity sensor, abasebenzisi banokulungisa uvakalelo baze bangene kwiibhokisi okanye kwiikhonteyina ezingezizo zesinyithi ukuze bafumane ulwelo lwangaphakathi okanye izinto eziqinileyo.
01 Isishwankathelo soBugcisa
I-capacitor equlathe iipleyiti ezimbini ivelisa intsimi yombane phakathi kweepleyiti xa isetyenziswa. Nasiphi na isixhobo esingena kweli ntsimi sitshintsha i-capacitance phakathi kweepleyiti.
I-capacitor isenokuba nepleyiti. Kule meko, "ipleyiti" yesibini yintambo yomhlaba.
Zonke ii-capacitive sensors zinezixhobo ezifanayo ezisisiseko.
1. Ii-Enclosures - Iindidi ngeendidi zeemilo, ubungakanani kunye nezinto zokwakha
2. Isixhobo senzwa esisisiseko - siyahluka ngokweteknoloji esetyenzisiweyo
3. Isekethe ye-elektroniki - ivavanya izinto ezifunyenwe zizinzwa
4. Uqhagamshelo lombane - Lubonelela ngemiqondiso yamandla kunye nemveliso
Kwimeko yee-capacitive sensors, i-base sensing element yi-capacitor yebhodi enye kwaye uqhagamshelo lwenye ipleyiti luphantsi komhlaba. Xa ithagethi isiya kwindawo yokufumanisa i-sensor, ixabiso le-capacitance liyatshintsha kwaye i-sensor output switches itshintshe.
1. i-capacitor
2. uqhagamshelo
3. Umphezulu wokungenisa
02 Izinto ezichaphazela umgama wokuziva we-sensor
Umgama obangelwayo ubhekisa kumgama obonakalayo obangela ukuba i-switch output itshintshe xa ithagethi isondela kumphezulu obangelwayo we-sensor kwicala le-axial.
Iphepha leeparameter zemveliso yethu lidwelisa imigama emithathu eyahlukeneyo:
Uluhlu lokuvaibhekisa kumgama oqhelekileyo ochazwe kwinkqubo yophuhliso, osekelwe kwithagethi yobukhulu obuqhelekileyo kunye nezinto.
Uluhlu Lokwenyani Lokuqondaiqwalasela ukuphambuka kwecandelo kubushushu begumbi. Imeko embi kakhulu yi-90% yoluhlu lokuva oluqhelekileyo.
Umgama Wokwenyani Wokusebenzaithathela ingqalelo ukushukuma kwe-switch point okubangelwa kukufuma, ukunyuka kwamaqondo obushushu kunye nezinye izinto, kwaye imeko embi kakhulu yi-90% yomgama obangelwayo. Ukuba umgama obangelwayo ubalulekile, lo ngumgama omele usetyenziswe.
Ngokwenyani, into leyo ayifane ibe nobukhulu obuqhelekileyo kunye nemilo eqhelekileyo. Impembelelo yobukhulu ekujoliswe kuyo iboniswe ngezantsi:
Umahluko kwimilo ongaqhelekanga kakhulu kunomahluko kubukhulu. Umfanekiso ongezantsi ubonisa isiphumo semilo yento ekujoliswe kuyo.
Kunzima ngokwenene ukubonelela ngesici sokulungisa esisekelwe kwimilo, ngoko ke uvavanyo luyafuneka kwiindawo apho umgama we-inductive ubalulekile.
Okokugqibela, into ephambili echaphazela umgama obangelwe yi-dielectric constant yethagethi. Kwii-sensors ze-capacitive level, kokukhona i-dielectric constant iphezulu, kokukhona kulula ukuyifumana le nto. Njengomgaqo jikelele, ukuba i-dielectric constant ingaphezulu kwe-2, le nto kufuneka ifumaneke. Ezi zilandelayo zii-dielectric constants zezinye izinto eziqhelekileyo ukuze zisetyenziswe kuphela.
03 Inzwa yokuchonga inqanaba
Ukuze usebenzise ngempumelelo ii-capacitive sensors ukufumanisa inqanaba, qinisekisa ukuba:
Iindonga zenqanawa azinazo isinyithi
Ubukhulu bodonga lwesikhongozeli bungaphantsi kwe-¼" -½"
Akukho sinyithi kufutshane nesenzi
Umphezulu wokungeniswa ubekwe ngqo eludongeni lwesikhongozeli
Ukufakwa kwezixhobo ze-sensor kunye nesikhongozeli
