ʻO nā ʻāpana excavator Hitachi EX200-2/3/5 kaomi hoʻololi sensor 4436271

Mekini hana

1) Ka hopena magnetoelectric

Wahi a ke kānāwai o Faraday no ka hoʻokomo electromagnetic, ʻo ka nui o ka ikaika electromotive i hoʻokomo ʻia i loko o ka coil e pili ana i ka loli o ka flux magnetic e hele ana i ka coil i ka wā e neʻe ai ka N-turn coil i ke kahua magnetic a ʻoki i ka laina mana magnetic ( a i ʻole ka hoʻololi ʻana o ka hoʻololi ʻana o ke kahua magnetic kahi i loaʻa ai ka coil).

ʻO ka mea ʻike magnetoelectric neʻe laina

ʻO ka linear neʻe magnetoelectric sensor aia i kahi magnet mau, kahi coil a me kahi hale sensor.

I ka wā e haʻalulu ai ka pūpū me ke kino vibrating e ana ʻia a ʻoi aku ka kiʻekiʻe o ke alapine vibration ma mua o ke alapine maoli o ka ʻike, no ka mea palupalu ka pūnāwai a ʻoi aku ka nui o ka nui o ka neʻe ʻana, ua lōʻihi loa ka ʻāpana neʻe. e haʻalulu (kū mālie) me ke kino haʻalulu. I kēia manawa, kokoke ka wikiwiki o ka neʻe ʻana ma waena o ka magnet a me ka coil i ka wikiwiki o ka vibrator.

ʻAno rotary

Hoʻopaʻa ʻia ka hao palupalu, coil a me ka magnet mau. Hoʻokomo ʻia ka mea ana i hana ʻia me nā mea conductive magnetic ma ke kino wili i ana ʻia. I kēlā me kēia manawa e hoʻololi ʻia ka niho, ua hoʻololi ʻia ka pale ʻana o ke kaapuni magnetic ma waena o ka mea ana a me ka hao palupalu i hoʻokahi manawa, a hoʻololi hoʻi ka puʻu magnetic i hoʻokahi manawa. ʻO ke alapine (helu o nā pulses) o ka ikaika electromotive i hoʻokomo ʻia i loko o ka coil ua like ia me ka huahana o ka helu o nā niho ma ke ana ana a me ka wikiwiki o ka huli ʻana.

Ka hopena hale

Ke hoʻokomo ʻia kahi semiconductor a i ʻole metala foil i loko o kahi māla magnetic, i ka wā e kahe ai kahi au (ma ke kuhikuhi mokulele o ka foil perpendicular to the magnetic field), hoʻokumu ʻia kahi mana electromotive ma ke ala e pili ana i ka māla magnetic a me ke au. Kapa ʻia kēia hanana ʻo Hall effect.

ʻElemu Hale

ʻO nā mea Hall maʻamau i hoʻohana ʻia he germanium (Ge), silicon (Si), indium antimonide (InSb), indium arsenide (InAs) a pēlā aku. N-type germanium mea maʻalahi e hana a he maikai Hall coefficient, wela hana a me linearity. P-type silicon ka maikaʻi loa linearity, a me kona Hall coefficient a me ka wela hana e like me ka N-type germanium, akā, kona electron neʻe haʻahaʻa a me kona hoʻoili ukana 'ilihune, no laila, ia mea maʻamauʻaʻole hoʻohana 'ia e like me hoʻokahi Hale. ʻeleʻele.
