Masensa eHoro anoenderana neHoro maitiro. Iyo Horo mhedzisiro inzira yekutanga yekudzidza zvimiro zve semiconductor zvinhu. Iyo Horo coefficient yakayerwa neHall effect kuyedza inogona kuona zvakakosha paramita senge conductivity mhando, mutakuri wemutakuri uye mutakuri wekufamba kwe semiconductor zvinhu.
Classification
Masensa eHoro akakamurwa kuita mutsara Hall sensors uye chinja Hall masensa.
1. Linear Hall sensor ine Hall element, linear amplifier uye emitter muteveri, uye zvinobuda analogi uwandu.
2. The switch-type Hall sensor inoumbwa ne voltage regulator, Hall element, differential amplifier, Schmitt trigger uye inobuda nhanho, uye inobuda digitaalinen uwandu.
Zvinhu zvakagadzirwa ne semiconductor zvinhu zvichibva paHoro mhedzisiro zvinonzi Hall zvinhu. Iyo ine zvakanakira kuve nehanya kune magineti minda, yakapusa muchimiro, diki muhukuru, yakafara mukupindura frequency, yakakura mukubuda kwevoltage kusiyanisa uye kureba muhupenyu hwesevhisi. Naizvozvo, yakashandiswa zvakanyanya mundima dzekuyera, otomatiki, komputa uye ruzivo tekinoroji.
Main application
Hall effect sensors anoshandiswa zvakanyanya senzvimbo sensors, kutenderera kumhanya kuyerwa, muganhu switch uye kuyerwa kwekuyerera. Mimwe michina inoshanda yakavakirwa paHararo mhedzisiro, yakadai seHall effect current sensors, Hall effect leaf switch, uye Hall effect magnetic field simba sensors. Tevere, iyo chinzvimbo sensor, inotenderera yekumhanyisa sensor uye tembiricha kana kudzvanywa sensor zvinonyanya kutsanangurwa.
1. Sensor yenzvimbo
Hall effect sensors inoshandiswa kunzwa kutsvedza kufamba, mune iyi mhando ye sensor pachave neyakadzora yakanyatso kudzora pakati peiyo horo element uye magineti, uye iyo induced magineti inoshanduka sezvo magineti inofamba ichidzoka nekudzoka pane yakagadziriswa gap. Kana chinhu chacho chiri pedyo nechokuchamhembe, munda uchave usina kunaka, uye kana chinhu chiri pedyo nechekumaodzanyemba, magnetic field ichava yakanaka. Aya ma sensors anonziwo proximity sensors uye anoshandiswa kune chaiyo chinzvimbo.
2. Speed sensor
Mukumhanya kunzwa, iyo Hall effect sensor inoiswa yakanyatsotarisana negineti inotenderera. Iyi magineti inotenderera inogadzira iyo magineti inodiwa kushandisa sensor kana Hall element. Kurongeka kwemagineti anotenderera kunogona kusiyana, zvichienderana nekunaka kwekushandisa. Zvimwe zvezvirongwa izvi ndezvekuisa magineti imwe chete pashaft kana hub kana kushandisa magineti emhete. Iyo Hall sensor inoburitsa inobuda pulse pese painotarisana nemagineti. Pamusoro pezvo, aya mapurusi anodzorwa ne processor kuona uye kuratidza kumhanya muRPM. Aya masensa anogona kuve edhijitari kana mutsara analog yekubuda ma sensors.
3. Temperature kana pressure sensor
Hall effect sensors inogonawo kushandiswa sekumanikidza uye tembiricha sensors, ma sensors aya anosanganiswa nekumanikidza kunobvisa diaphragm ine magineti akakodzera, uye magineti kuungana kwemabhero kunobata Horo mhedzisiro chinhu kumashure nekudzoka.
Muchiitiko chekuyerwa kwekumanikidza, mabhero ari pasi pekuwedzera uye kuputika. Shanduko mumabhero anoita kuti gungano remagineti riswedere pedyo neHoro effect element. Naizvozvo, iyo inokonzeresa yekubuda voltage inoenzanirana neyakaiswa pressure.
Panyaya yezviyero zvetembiricha, gungano remabhero rakavharwa negasi rine hunhu hunozivikanwa hwekuwedzera kupisa. Kana kamuri ichipisa, gasi riri mukati memhepo rinowedzera, izvo zvinoita kuti sensor igadzire voltage yakaenzana nekushisa.
