Zvinoenderana nechimiro chechinhu chakaonekwa, mashandisiro avo eMagnetic Hall effect sensor anogona kukamurwa kuita yakananga application uye isina kunanga application. Iyo yekutanga ndeyekuona zvakananga iyo magineti kana magineti maitiro echinhu chakaedzwa, uye chekupedzisira ndechekuona yakagadziriswa magineti pachinhu chakaedzwa. Iyi magnetic field ndiyo inotakura ruzivo rwakaonekwa. Kuburikidza naro, akawanda asiri emagetsi uye asiri magineti emuviri uwandu, senge kumhanya, kukurumidza, kona, angular velocity, revolutions, kutenderera kumhanya uye nguva iyo inoshanda shanduko inoshandurwa kuita huwandu hwemagetsi kuona uye kutonga.
Hall effect sensors yakakamurwa kuita dijitari uye analog mhando zvichienderana neinobuda chiratidzo.
Iyo inobuda voltage yedhijitari inobuda Hall effect sensors ine hukama hwemutsara nekusimba kweiyo yakaiswa magineti.
Analog inobuda Hall effect sensor ine Hall element, linear amplifier uye emitter muteveri, iyo inoburitsa analog uwandu.
Displacement Measurement
Iwo maviri anogara magineti akafananaNeodymium Magnetsakaiswa ne polarity yakafanana. Iyo digital Hall sensor inoiswa pakati, uye yayo magineti induction intensity i zero. Iyi poindi inogona kushandiswa sezero point yekutamisa. Kana iyo horo sensor ikaita kusimuka, sensor ine voltage inobuda, uye iyo voltage yakanangana nekutama.
Kuyera kwesimba
Kana maparameter akadai sekunetsana uye kudzvanywa akashandurwa kuita kutama, ukuru hwekunetsana uye kudzvanywa kunogona kuyerwa. Maererano nemusimboti uyu, simba re sensor rinogona kuitwa.
Angular Velocity Measurement
Namira chidimbu chesimbi yemagineti pamucheto wediski yeasiri magineti zvinhu, isa sensor horo padyo nemupendero wedhisiki, tenderedza dhisiki kune imwe kutenderera, iyo horo sensor inoburitsa pulse, kuitira kuti nhamba yekuchinja ( counter) inogona kuyerwa. Kana iyo frequency mita yakabatana, kumhanya kunogona kuyerwa.
Linear Velocity Measurement
Kana iyo switching Hall sensor inogara yakarongedzwa panjanji zvinoenderana nenzvimbo yakafanotemerwa, iyo pulse chiratidzo inogona kuyerwa kubva kuyeredhi redunhu kana inogara magineti yakafanana.Samarium Cobaltyakaiswa pamotokari inofamba inopfuura nayo. Kumhanya kwekufambisa kwemotokari kunogona kuyerwa zvichienderana nekugoverwa kwechiratidzo chepulse.
Kushandiswa kweHoro Sensor Tekinoroji muIndasitiri yeMotokari
Hall sensor tekinoroji inoshandiswa zvakanyanya muindasitiri yemotokari, kusanganisira simba, kudzora muviri, traction control uye anti lock braking system.
Iyo fomu yeHall sensor inosarudza mutsauko wekusimudzira wedunhu, uye kuburitsa kwayo kunofanirwa kuenderana neinodzorwa mudziyo. Ichi chinobuda chinogona kunge chiri analog, senge yekumhanyisa chinzvimbo sensor kana throttle chinzvimbo sensor; kana dhijitari, senge crankshaft kana camshaft chinzvimbo sensor.
Kana Hall element ichishandiswa analog sensor, sensor iyi inogona kushandiswa thermometer mune air conditioning system kana throttle chinzvimbo sensor mune simba rekudzora system. Iyo horo element yakabatana neyekusiyanisa amplifier, uye amplifier yakabatana neNPN transistor. Iyo magineti isingaperiNdFeB or SmCoinogadziriswa pane shaft inotenderera. Kana shaft ichitenderera, iyo magnetic field pane horo element inosimbiswa. Iyo Horo voltage inogadzirwa inoenderana nesimba remagineti.
Kana iyo horo yemukati ichishandiswa masaini edhijitari, senge crankshaft chinzvimbo sensor, camshaft chinzvimbo sensor kana mota yekumhanyisa sensor, dunhu rinofanirwa kushandurwa kutanga. Iyo horo element yakabatana neyekusiyanisa amplifier, iyo yakabatana neiyo Schmidt trigger. Mukugadzirisa uku sensor inoburitsa chiratidzo chekubatidza kana kudzima. Mumaseketi mazhinji emotokari, maHoro sensors ndeazvino anotora kana epasi masaini maseketi. Kuti upedze basa iri, NPN Transistor inoda kuve yakabatana nekubuda kweSchmitt trigger. Iyo magineti inopfuura nepakati peiyo horo element, uye blade pavhiri retrigger inopfuura pakati pemagineti uye horo element.
