Ezinhlelweni zanamuhla zezimboni, izinzwa ezivundisayo zokuthola isikhundla zibalulekile. Uma kuqhathaniswa nezinkinobho zomshini, zingadala izimo ezicishe zifaneleke kakhulu: ukutholwa kokungathintani, ukungagugi, imvamisa yokushintsha ephezulu kanye nokunemba kokushintsha okuphezulu. Ngaphezu kwalokho, azizweli ekudlidlizeni, uthuli kanye nomswakama. Izinzwa ezivundisayo zingabona zonke izinsimbi ezingewona othintana nazo. Zaziwa nangokuthi izinkinobho zokusondelana ezivundisayo noma izinzwa ezivundisayo.
Isetshenziswa kabanzi futhi inganciphisa ukuqoqwa kwempahla
Izinzwa ezivundisayo zinezinhlelo zokusebenza eziningi, ikakhulukazi ekutholeni nasekuqapheni izindawo zezingxenye zensimbi. Izinzwa ezivundisayo zifaneleka kakhulu embonini yezimoto, embonini yokudla, embonini yamathuluzi omshini, njll. Izinkinobho zokusondela ezivundisayo zingasetshenziswa ezindaweni eziyingozi. Ubuchwepheshe bayo be-NAMUR noma i-casing eqinile kungaqinisekisa izinga elithile lamandla okumelana nokuqhuma.
Izinto zokwakha izinzwa ezisebenzisa i-inductive ngokuvamile ziyi-alloy ye-nickel-copper noma insimbi engagqwali. Phakathi kwazo, lokhu kokugcina kufaneleka kakhulu ezindaweni ezinomswakama ophezulu noma ezigqwalisayo. Ngesakhiwo sazo esiqinile kanye nesimiso sokusebenza esingagugi, lezi zinzwa zingasetshenziswa njengezixazululo ezinokwethenjelwa ezinhlelweni eziningi. Ezinhlelweni zokusebenza lapho kukhona khona i-slag spatter, izinzwa ezisebenzisa i-inductive nazo zingambozwa ngezingubo ezikhethekile, njenge-PTFE coating noma izinto ezifanayo.
Umgomo wokusebenza wezinzwa ezikhuthazayo
Izinzwa ezivundisayo zenza ukutholwa kwezinto zensimbi ngaphandle kokuthintana ngokuthola izinguquko emasimini kagesi. Zisebenza ngokusekelwe esimisweni sokungeniswa kwe-electromagnetic: lapho insimu yamagnetic ishintsha, kukhiqizwa i-voltage ebangelwayo kumqhubi.
Ubuso bokuzwa balesi sinzwa bukhipha amasimu kagesi asebenza ngesivinini esiphezulu. Uma into yensimbi isondela, insimu yamagnetic yesinzwa izothinteka yinto kanye noshintsho. Lolu shintsho luzotholwa yisisi bese luguqulwa lube isignali yokushintsha ukuze kuboniswe ukuba khona kwento.
Imiklamo yezinzwa ezisebenzisa i-inductive iyahlukahluka, futhi amabanga azo okushintsha ahambisanayo nawo ayahlukahluka. Uma ibanga lokushintsha lilikhulu, ububanzi bokusetshenziswa kwenzwa buyanda. Isibonelo, ingasetshenziswa ezinhlelweni zokusebenza lapho inzwa ingenakufakwa ngqo eduze kwento.
Ekuphetheni, izinzwa ezisebenzisa i-inductive zisebenza ngokunemba okuphezulu futhi zithembekile. Ngenxa yesimiso sazo sokusebenza esingathintani kanye nezinhlobo ezahlukene zokuklama, ziyimishini ebalulekile ezinhlotsheni eziningi zokusebenza ezenzakalelayo zezimboni.

Imiklamo ehlukahlukene ivumela ukutholwa okuguquguqukayo
Ngenxa yokubekezelela okuncane kokulinganisa, izinzwa ezikhuthazayo zingaqinisekisa ukutholwa okuthembekile. Ibanga lokushintshana kwezinzwa ezikhuthazayo liyahlukahluka kuye ngomklamo. Isibonelo, ibanga lokushintshana lezinzwa ezinkulu ezikhuthazayo lingafinyelela ku-70mm. Izinzwa ezikhuthazayo ziza ngezinhlobo ezahlukene zokufaka: Izinzwa ezikhuthazayo ziyaguquguquka endaweni yokufaka, kuyilapho izinzwa ezingezona ezikhuthazayo ziphuma ngamamilimitha ambalwa, zifinyelela ibanga elikhulu lokushintshana.
Ibanga lokubona lama-inductive sensors lithintwa yi-coefficient yokulungisa, kanti ibanga lokushintsha izinsimbi ngaphandle kwensimbi lincane. I-LANBAO ingahlinzeka ngama-inductive sensors anganciphiswanga ane-correction factor engu-1, ane-switching range efanayo yazo zonke izinsimbi. Ama-inductive sensors ngokuvamile asetshenziswa njenge-PNP/NPN evame ukuvula noma ukuvala oxhumana nabo. Amamodeli anomphumela we-analog angahlangabezana nezidingo ezikhethekile kakhulu.

Iqinile futhi ithembekile - Izinga eliphezulu lokuvikela elifanele izindawo ezinzima
Njengoba zinobubanzi bokushisa bokusebenza kanye nezinga eliphezulu lokuvikelwa, lezi zinzwa zifaneleka kakhulu ukusetshenziswa ezindaweni zezimboni ezinzima. Phakathi kwazo, izinzwa ezikhuthazayo ezinezinga lokuvikelwa le-IP68 zisebenza kahle kakhulu ekuvaleni nasekusetshenzisweni okukhulu ezimbonini ezifana nokudla, imithi, kanye nemishini yokwakha. Izinga lokushisa lazo lokusebenza lingafinyelela ku-85 °C okungenani.
Isixhumi se-M12 siqinisekisa ukufakwa okulula
Isixhumi se-M12 siyindlela ejwayelekile yokuxhuma izinzwa ngoba singaqinisekisa ukufakwa okusheshayo, okulula nokunembile. I-LANBAO iphinde inikeze izinzwa zokungenisa ezinokuxhumeka kwekhebula, ezivame ukufakwa ezinhlelweni zokusebenza ezinesikhala esilinganiselwe. Ngenxa yokusetshenziswa kwayo okubanzi kanye nokuthembeka okuphezulu, izinzwa zokungenisa ziyizingxenye ezibalulekile kubuchwepheshe besimanje bokuzenzakalela futhi zisetshenziswa emikhakheni eminingi yezimboni.
