Ukushintshwa komhlanga kanye nezinzwa zomphumela wehholo
Izinzwa ezibucayi zisetshenziswa kukho konke kusuka ezimotweni kuya kumaselula. Yikuphi uzibuthe okufanele ngisebenzise inzwa yami kazibuthe? Ingabe kufanele ngisebenzise inzwa ye-hallf effect noma ukushintshwa komhlanga? Ngabe uzibuthe kufanele athathwe kanjani enzwa? Yini ukubekezelela okufanele ngikhathazeke ngayo? Funda kabanzi nge-K & J Hamba-ngokusebenzisa inhlanganisela inhlanganisela ye-Magnet-Sensor.

Yini i-Reed switch?

Izinzwa ezimbili ezithinta ihholo kanye nokushintshwa komhlanga. Ukushintshwa komhlanga kungakwesokudla.
I-Reed switch i-switch eshintshiwe kagesi esetshenziswa amandla kazibuthe asetshenzisiwe. Siqukethe othintana nabo oxhumana nabo ku-Ferrous Metal Reeds emvilophini yengilazi ye-Airtight. Oxhumana nabo bavame ukuvula, kungenzelanga ngogesi. Ukushintshwa kufakwe (kuvaliwe) ngokuletha uzibuthe eduze kwe-switch. Lapho uzibuthe ukhishwe, i-Reed switch izobuyela esimweni sayo sokuqala.

Yini inzwa ye-Hall Effect?
I-Hall Effect Sensor iyi-transducer ehlukahluka ngokuphuma kwamandla athile ngokuphendula ushintsho ku-magnetic field. Ngandlela-thile, izinzwa ze-Hall Effect zingagcina zenza umsebenzi ofanayo ne-Reed switch, kodwa ngaphandle kwezingxenye ezinyakazayo. Cabanga ngakho njengengxenye eqinile yombuso, okuhle kwezicelo zedijithali.

Yikuphi kwalezi zinzwa ezimbili ezilungele uhlelo lwakho lokusebenza kuncike ezintweni eziningi. Izici zifaka izindleko, ukuqondiswa kwama-magnet, ububanzi obuvame (ukushintshwa komhlanga ngokujwayelekile akusebenzi ngaphezulu kwe-10 KHZ), ukugoqa kwesiginali kanye nokwakhiwa komjikelezo we-logic ohambisana nawo.

Magnet - I-Sensor Orientation
Umehluko osemqoka phakathi kokushintshwa komhlanga kanye nezinzwa ze-Hall Effect Sensors kuyindlela efanelekile edingekayo kubunzi bokuvutha. Izinzwa ze-Hall Effect zisebenze lapho amandla kazibuthe athi inzwa ye-perpendicular eya enzwa eqinile yombuso. Iningi libheka iSouth Pole yaseSouth incane ukuba ibhekele indawo ekhonjisiwe enzwa, kepha hlola ishidi lokucacisa lenzwa yakho. Uma uvula izibuthe emuva noma eceleni, inzwa ngeke isebenze.

Ukushintshwa komhlanga kuyithuluzi elilungisiwe elinezingxenye ezinyakazayo. Siqukethe izintambo ezimbili ze-ferromagnetic ezihlukaniswe igebe elincane. Lapho ebusweni bukazibuthe obufana nalezo zintambo, bazothintana, benza ukuxhumana ngogesi. Ngamanye amagama, i-magnetic axis ye-magnet kufanele ihambisane ne-axis ende yokushintshwa komhlanga. UHamlin, umenzi we-Reed switch, unenothi elihle kakhulu lesicelo ngale ndaba. Kubandakanya imidwebo emikhulu ekhombisa izindawo nokuqondiswa lapho inzwa isebenza khona.
Ukuqondiswa kwe-Magnet okufanele: inzwa ye-hallf effect (kwesobunxele) vs switch (kwesokudla)
Kumele kwaziwe ukuthi okunye ukucushwa kungenzeka futhi kuvame ukusetshenziswa. Isibonelo, izinzwa ze-Hall Effect zikwazi ukubona ama-blades ensimbi "fan spinning". " Amabala ensimbi we-fan adlula phakathi kokumiswa kwezinzwa omile kanye nenzwa yokuma. Lapho insimbi iphakathi kwalokhu okubili, amandla kazibuthe aqondiswa kabusha ku-sensor (ivinjiwe) bese kuvulwa switch. Lapho insimbi ihamba ibangana, uzibuthe uvala ukushintshwa
