Kwiinkalo ezinqamlekileyo ezifana nokuveliswa kwe-chip ye-semiconductor kunye nokuhlolwa ngokuchanekileyo kwe-optical, ii-sensor ezichanekileyo zixhobo eziphambili zokufumana idatha ephambili. Nangona kunjalo, iimeko ezintsonkothileyo ze-electromagnetic kunye neemeko zomzimba ezingazinzanga zihlala zikhokelela kwidatha yokulinganisa engachanekanga. Isiseko se-granite, kunye ne-non-magnetic, iipropathi ezikhuselekileyo kunye nozinzo olubalaseleyo lomzimba, lwakha indawo ethembekileyo yokulinganisa inzwa.
Ubume obungeyo-magnetic busika umthombo wokuphazamiseka
Abenzi boluvo abachaneke kakhulu abanje nge-inductive displacement sensors kunye ne-magnetic scale scales zinovakalelo olugqithisileyo kutshintsho kwi-magnetic field. Umazibuthe okhoyo weziseko zentsimbi zemveli (ezifana nentsimbi kunye nealloyi ye-aluminiyam) unokudala umhlaba ophazamisayo wamagnetic ojikeleze inzwa. Xa isivamvo sisebenza, uphazamiso lwangaphandle lwemagnethi lusebenzisana nendawo yangaphakathi yamagnetic, enokubangela lula ukutenxa kwedatha yomlinganiselo.
I-Granite, njengelitye lendalo elivuthayo, liqulunqwe ngamaminerali afana ne-quartz, i-feldspar kunye ne-mica. Ubume bayo bangaphakathi bumisela ukuba ayinayo imagnethi konke konke. Faka inzwa kwisiseko segranite ukuphelisa ukuphazamiseka kwamagnetic kwesiseko ukusuka kwingcambu. Kwizixhobo ezichanekileyo ezifana ne-electron microscopes kunye ne-nuclear magnetic resonance, isiseko segranite siqinisekisa ukuba inzwa ibamba ngokuchanekileyo utshintsho olufihlakeleyo lwento ekujoliswe kuyo, ukuphepha iimpazamo zokulinganisa ezibangelwa ukuphazamiseka kwamagnetic.
Iimpawu zesakhiwo zilungelelaniswa kunye ne-electromagnetic shielding
Nangona igranite ingenaso isakhono sokukhusela njengesinyithi, ubume bayo obukhethekileyo bomzimba bunokwenza buthathaka ukuphazamiseka kombane. I-Granite ilukhuni ngokuthungwa kwaye ixinene kwisakhiwo. Ilungiselelo elidibeneyo leekristale zamaminerali zenza umqobo womzimba. Xa amaza ombane angaphandle esasazeka kwisiseko, inxalenye yamandla ifunxwa yikristale kwaye iguqulwe ibe ngamandla obushushu, kwaye inxalenye ibonakaliswa kwaye isasazeke kumphezulu wekristale, ngaloo ndlela inciphisa ubunzulu bamaza ombane afikelela kwinzwa.
Kwizicelo ezisebenzayo, iziseko zegranite zihlala zidibaniswa kunye nenetha zokukhusela isinyithi ukwenza izakhiwo ezidibeneyo. Umnatha wesinyithi uvimba amaza e-electromagnetic aphezulu, kwaye igranite yenza buthathaka ngakumbi uphazamiseko olushiyekileyo ngelixa ibonelela ngenkxaso ezinzileyo. Kwiindibano zocweyo zemizi-mveliso ezizaliswe ziziguquli ezihamba rhoqo kunye neenjini, le ndibaniselwano yenza ukuba abenzi boluvo basebenze ngokuzinzileyo nakwindawo eyomeleleyo ye-electromagnetic.
Zinzisa iipropati zomzimba kunye nokwandisa ukuthembeka komlinganiselo
I-coefficient yokwandiswa kwe-thermal ye-granite iphantsi kakhulu (kuphela (4-8) × 10⁻⁶/℃), kwaye ubukhulu bayo butshintsha kakhulu xa ubushushu buguquka, buqinisekisa ukuzinza kwendawo yokufakela inzwa. Ukusebenza kwayo okugqwesileyo kokudambisa kunokufunxa ngokukhawuleza ukungcangcazela kokusingqongileyo kunye nokunciphisa impembelelo yokuphazamiseka koomatshini kwimilinganiselo. Kwimilinganiselo echanekileyo ye-optical, isiseko se-granite sinokuthintela i-optical path offset ebangelwa yi-thermal deformation kunye ne-vibration, iqinisekisa ukuchaneka kunye nokuphindaphinda kwedatha yokulinganisa.
Kwimeko yokubhaqwa kobukhulu be-wafer ye-semiconductor, emva kokuba ishishini elithile lamkele isiseko segranite, impazamo yokulinganisa yehla ukusuka ku-±5μm ukuya ngaphakathi kwe-±1μm. Kwifom kunye nokuhlolwa kokunyamezela kwendawo yamacandelo e-aerospace, inkqubo yokulinganisa usebenzisa isiseko se-granite iphucule ukuphindaphinda kwedatha ngaphezu kwe-30%. Ezi meko zibonisa ngokupheleleyo ukuba isiseko segranite siphucula ngokubonakalayo ukuthembeka komlinganiso weenzwa ezichanekileyo ngokususa uphazamiseko lwe-electromagnetic kunye nokuzinzisa okusingqongileyo okubonakalayo, kuyenza ibe licandelo elibalulekileyo eliyimfuneko kwinkalo yokulinganisa ichanekile yanamhlanje.
