Kodi Masiwichi a Magnetic Proximity Amagwira Ntchito Bwanji?

Kusinthana kwa maginito ndi mtundu wakusinthana kwapafupi, komwe ndi imodzi mwamitundu yambiri m'banja la sensa. Amapangidwa ndi mfundo yogwirira ntchito yamagetsi komanso ukadaulo wapamwamba, ndipo ndi mtundu wa sensor yamalo. Itha kusintha kuchuluka kwamafuta osagwiritsa ntchito magetsi kapena kuchuluka kwa ma elekitiromu kukhala chizindikiro chamagetsi chomwe mukufuna kudzera pakusintha kwa ubale pakati pa sensa ndi chinthucho, kuti mukwaniritse cholinga chowongolera kapena kuyeza.

Kusintha kwa maginito oyandikira kumatha kukwaniritsa mtunda wodziwikiratu kwambiri ndi voliyumu yaying'ono yosinthira. Imatha kuzindikira zinthu zamaginito (nthawi zambiri maginito okhazikika), kenako imatulutsa chiwopsezo chosinthira chizindikiro. Popeza mphamvu ya maginito imatha kudutsa muzinthu zambiri zomwe sizikhala ndi maginito, njira yoyambitsira sikutanthauza kuti chinthu chomwe mukufuna kuti chikhale pafupi ndi malo opangira maginito oyandikira maginito. M'malo mwake, mphamvu ya maginito imatumizidwa kumtunda wautali kudzera pa maginito conductor (monga chitsulo). Mwachitsanzo, ma signature amatha kutumizidwa ku switch ya maginito oyandikira kutentha kwambiri kuti apange chizindikiro choyambitsa.

Mfundo yogwiritsira ntchito maginito oyandikana nawo:

Kusintha kwa maginito oyandikira kumatha kukwaniritsa mtunda wodziwikiratu kwambiri ndi voliyumu yaying'ono yosinthira. Imatha kuzindikira zinthu zamaginito (nthawi zambiri maginito okhazikika), kenako imatulutsa chiwopsezo chosinthira chizindikiro. Popeza mphamvu ya maginito imatha kudutsa muzinthu zambiri zomwe sizikhala ndi maginito, njira yoyambitsira sikutanthauza kuti chinthu chomwe mukufuna kuti chikhale pafupi ndi malo olowera maginito oyandikira maginito, koma imatumiza mphamvu ya maginito kudzera mu kondakitala maginito (monga chitsulo). ) mpaka mtunda wautali. Mwachitsanzo, chizindikirocho chikhoza kutumizidwa ku maginito oyandikira maginito kupyolera mu kutentha kwakukulu kuti apange chizindikiro choyambitsa chinthu.

Zimagwira ntchito ngati cholumikizira cholumikizira cholumikizira, chokhala ndi LC oscillator, choyambitsa chizindikiro, ndi cholumikizira chosinthira, komanso amorphous, cholowera kwambiri chachitsulo chachitsulo chomwe chimayambitsa kuwonongeka kwa eddy ndikuchepetsa mayendedwe ozungulira. Ngati aikidwa mu mphamvu ya maginito (mwachitsanzo, pafupi ndi maginito okhazikika), pachimakecho amapangidwa kuti achepetse mafupipafupi a dera la oscillation. Panthawiyi, kuwonongeka kwa eddy komwe kumakhudza kuchepetsedwa kwa dera la oscillation kudzachepetsedwa, ndipo dera la oscillation silidzachepetsedwa. Chifukwa chake, mphamvu yogwiritsidwa ntchito ndi maginito oyandikira maginito imawonjezeka chifukwa cha kuyandikira kwa maginito osatha, ndipo choyambitsa chizindikiro chimatsegulidwa kuti chipange chizindikiro. Ili ndi ntchito zambiri, monga: ikhoza kudutsa mu chidebe cha pulasitiki kapena ngalande kuti izindikire chinthucho; Kuzindikira kwa chinthu kumalo otentha kwambiri; Njira yothetsera zinthu; Gwiritsani ntchito maginito kuti muzindikire manambala, ndi zina.
