Muminda yemazuva ano yakadai sekugadzira machipisi e semiconductor uye kuongorora kwe optical kwakanyatsojeka, masensa e high-precision ndiwo midziyo mikuru yekuwana data rakakosha. Zvisinei, nharaunda dzakaoma dze electromagnetic uye mamiriro emuviri asina kugadzikana zvinowanzo tungamira ku data rekuyera risina kururama. Hwaro hwe granite, hune hunhu hwayo husina simba remagineti, hwakachengetedzwa uye kugadzikana kwakanaka kwemuviri, hunovaka nharaunda yekuyera yakavimbika yesensa.
Hunhu husina simba remagineti hunobvisa chikonzero chekupindira
Masensa ane kunyatsojeka akadai semasensa ekudzikisa magetsi einductive displacement uye ma magnetic scale scales anonyanya kunzwa shanduko mumunda wemagineti. Magnetism inowanikwa mumabhesi esimbi echinyakare (akadai sesimbi nealuminium alloy) inogona kugadzira simba remagineti rinopindirana rakatenderedza sensor. Kana sensor iri kushanda, simba remagineti rinopindirana neinternal magnetic field, izvo zvinogona kukonzera kutsauka kwedata rekuyera.
Granite, sedombo rechisikigo reigneous, inoumbwa nezvicherwa zvakaita se quartz, feldspar ne mica. Maumbirwo ayo emukati anoratidza kuti haina magnetism zvachose. Isa sensor pachigadziko chegranite kuti ubvise kupindirana kwemagineti kwechigadziko kubva pamudzi. Muzvishandiso zvemagineti zvakaita se electron microscopes uye nuclear magnetic resonance, base yegranite inoita kuti sensor inyatsobata shanduko dzisinganzwisisike dzechinhu chakanangana nacho, ichidzivirira zvikanganiso zvekuyera zvinokonzerwa nekupindirana kwemagineti.
Hunhu hwechivakwa hunobatanidzwa ne electromagnetic shielding
Kunyangwe granite isina simba rekudzivirira kufambisa mhepo sesimbi, chimiro chayo chemuviri chakasiyana chinogonawo kuderedza kupindira kwemagetsi. Granite yakaoma muchimiro uye yakakora muchimiro. Kurongeka kwemakristaro emaminerari kunoumba chipingamupinyi chemuviri. Kana mafungu emagetsi ekunze akapararira kusvika pasi, chikamu chesimba chinotorwa nekristaro uye chinoshandurwa kuita simba rekupisa, uye chikamu chinoratidzwa uye chinopararira pamusoro pekristaro, nokudaro zvichideredza kusimba kwemafungu emagetsi anosvika pasensor.
Mukushandiswa kwazvinoita, mabhesi egranite anowanzo sanganiswa nemambure ekudzivirira esimbi kuti agadzire zvivakwa zvakasanganiswa. Mesh yesimbi inovhara mafungu emagetsi ane frequency yakakwira, uye granite inowedzera kushayisa simba kupindira kwasara uku ichipa rutsigiro rwakagadzikana. Mumafekitori eindasitiri akazadzwa nema frequency converters nemamota, musanganiswa uyu unogonesa masensa kushanda zvakadzikama kunyangwe munzvimbo ine electromagnetic yakasimba.
Gadzirisa hunhu hwemuviri uye wedzera kuvimbika pakuyera
Kuwanda kwekuwedzera kwegranite mukupisa kwakaderera zvikuru (chete (4-8) ×10⁻⁶/℃), uye saizi yayo inochinja zvishoma kana tembiricha ichichinja-chinja, zvichiita kuti nzvimbo yekuisa sensor igare yakasimba. Kushanda kwayo kwakanaka kwekudzivirira mvura kunogona kukurumidza kupinza kudengenyeka kwezvakatipoteredza uye kuderedza simba remakanika pakuyera. Mukuyera kwakanyatsojeka, granite base inogona kudzivirira nzira ye optical inokonzerwa nekushanduka kwekupisa uye kudedera, ichivimbisa kururama uye kudzokorora kwedata rekuyera.
Muchiitiko chekuona ukobvu hwe semiconductor wafer, mushure mekunge rimwe bhizinesi ratora granite base, kukanganisa kwekuyera kwakadzikira kubva pa ± 5μm kusvika mukati me ± 1μm. Mukuongorora kwechimiro uye chinzvimbo chezvikamu zvemuchadenga, sisitimu yekuyera inoshandisa granite base yakavandudza kugona kudzokororwa kwedata neinopfuura 30%. Nyaya idzi dzinoratidza zvizere kuti granite base inowedzera zvakanyanya kuvimbika kwekuyera kwemasensa ane hungwaru hwepamusoro nekubvisa kupindira kwemagetsi uye kugadzikana kwenzvimbo, zvichiita kuti ive chinhu chakakosha mumunda wekuyera kwehungwaru hwemazuva ano.
