Kwimimandla ephambili efana nokuveliswa kweetshiphu ze-semiconductor kunye nokuhlolwa kwe-optical ngokuchanekileyo, ii-sensors ezichanekileyo kakhulu zezona zixhobo ziphambili zokufumana idatha ebalulekileyo. Nangona kunjalo, iindawo ezintsonkothileyo ze-electromagnetic kunye neemeko zomzimba ezingazinzanga zihlala zikhokelela kwidatha yokulinganisa engachanekanga. Isiseko segranite, esineempawu zayo ezingezizo zemagnethi, ezikhuselweyo kunye nozinzo oluphezulu lomzimba, sakha indawo yokulinganisa ethembekileyo ye-sensor.
Indalo engeyiyo imagnethi inqumla umthombo wokuphazamiseka
Izinzwa ezichanekileyo kakhulu ezifana nezinzwa zokufuduka ezibangela ukuguquka kunye nezikali zesikali semagnethi zinobuthathaka kakhulu kutshintsho olukwintsimi yemagnethi. Imagnethi yendalo yeziseko zesinyithi zemveli (ezifana nentsimbi kunye ne-aluminium alloy) inokudala intsimi yemagnethi ephazamisayo ejikeleze inzwa. Xa inzwa isebenza, intsimi yemagnethi ephazamisayo yangaphandle isebenzisana nentsimi yemagnethi yangaphakathi, enokubangela ukuphambuka kwedatha yokulinganisa ngokulula.
I-granite, njengelitye lendalo eliyi-igneous, yenziwe ngeeminerali ezifana ne-quartz, i-feldspar kunye ne-mica. Ulwakhiwo lwayo lwangaphakathi lubonisa ukuba ayinamagnetism konke konke. Faka i-sensor kwisiseko se-granite ukuze kupheliswe ukuphazamiseka kwe-magnetic kwesiseko ukusuka kwingcambu. Kwizixhobo ezichanekileyo ezifana nee-electron microscopes kunye ne-nuclear magnetic resonance, isiseko se-granite siqinisekisa ukuba i-sensor ibamba ngokuchanekileyo utshintsho oluncinci lwento ekujoliswe kuyo, iphephe iimpazamo zokulinganisa ezibangelwa kukuphazamiseka kwe-magnetic.
Iimpawu zesakhiwo zihambelana nokukhusela nge-electromagnetic
Nangona igranite ingenawo amandla okukhusela njengeentsimbi, ulwakhiwo lwayo olukhethekileyo lomzimba lunokunciphisa ukuphazamiseka kwe-electromagnetic. Igranite iqinile ngobume kwaye ixinene kwisakhiwo. Ulungiselelo oludibeneyo lweekristale zezimbiwa lwenza umqobo obonakalayo. Xa amaza e-electromagnetic angaphandle esasazeka kwisiseko, inxalenye yamandla ifunxwa yikristale kwaye iguqulwe ibe ngamandla obushushu, kwaye inxalenye iyabonakaliswa kwaye isasazeke kumphezulu wekristale, ngaloo ndlela kunciphisa amandla amaza e-electromagnetic afikelela kwi-sensor.
Kwimisebenzi ebonakalayo, iziseko zegranite zihlala zidityaniswe ne-metal shielding nets ukuze zenze izakhiwo ezidityanisiweyo. I-mesh yesinyithi ivimba amaza e-electromagnetic aphindaphindayo, kwaye i-granite iyenza buthathaka ngakumbi i-residue interference ngelixa inika inkxaso ezinzileyo. Kwii-workshops zoshishino ezizaliswe zii-frequency converters kunye nee-motors, olu dibaniso lwenza ukuba ii-sensors zisebenze ngokuzinzileyo nokuba kwindawo enamandla ye-electromagnetic.
Zinzisa iipropati zomzimba kwaye womeleze ukuthembeka kokulinganisa
I-coefficient yokwandiswa kobushushu begranite iphantsi kakhulu (kuphela (4-8) ×10⁻⁶/℃), kwaye ubungakanani bayo buyatshintsha kancinci xa ubushushu butshintshatshintsha, okuqinisekisa uzinzo lwendawo yokufakwa kwesensor. Ukusebenza kwayo okugqwesileyo kokudambisa kunokufunxa ngokukhawuleza ukungcangcazela kwendalo kwaye kunciphise impembelelo yokuphazamiseka koomatshini kwimilinganiselo. Kumlinganiselo ochanekileyo wokukhanya, isiseko segranite sinokuthintela ukususwa kwendlela yokukhanya okubangelwa kukuguquguquka kobushushu kunye nokungcangcazela, okuqinisekisa ukuchaneka kunye nokuphindaphinda kwedatha yokulinganisa.
Kwimeko yokufunyanwa kobukhulu be-wafer ye-semiconductor, emva kokuba ishishini elithile lithathe isiseko se-granite, impazamo yokulinganisa yehla ukusuka kwi-±5μm ukuya kwi-±1μm. Kwisimo kunye nokuhlolwa kokunyamezelana kweendawo ze-aerospace, inkqubo yokulinganisa esebenzisa isiseko se-granite iphucule ukuphindaphindwa kwedatha ngaphezulu kwe-30%. Ezi meko zibonisa ngokupheleleyo ukuba isiseko se-granite siphucula kakhulu ukuthembeka kokulinganisa kwee-sensors ezichanekileyo ngokuphelisa ukuphazamiseka kwe-electromagnetic kunye nokuzinzisa imeko-bume ebonakalayo, okwenza ukuba ibe yinxalenye ebalulekileyo kwintsimi yokulinganisa ngokuchanekileyo yanamhlanje.
