Ukuthola ukunemba kwenhliziyo ephezulu kakhulu kwengcindezelo yengcindezelo, udinga isiginali yokuphuma engalimali kalula futhi inesinqumo esiphakeme kakhulu.
1. Yehlisa ukulahleka kwesiginali nokuphazamiseka
Isiginali yokuphuma yedijithali ayikhonjelwa ekulahlekelweni kwesiginali noma ukuphazamiseka njengesiginali ye-analog, ngaphandle kwalokho isiginali esingahleliwe sizodlula njengoba kwasekuqaleni kwavela inzwa yengcindezi. Noma cha.
Ukuthola ukulungiswa okuphezulu kusiginali yokuphuma, isiguquli esinamandla esinamandla esinedijithali esinesinqumo okungenani esingu-16 bits kuyadingeka ukufeza izinga lokunemba elingcono kune-0.01% yesilinganiso esigcwele.
2. Yehlisa amaphutha wokuguqula ama-analog-kuya-digital
Futhi, asikho isidingo sedijithali ukufakwa ku-analog kunoma yisiphi isigaba phakathi kwenzwa yokucindezela nokubonisa noma ukuqopha, njengoba kungaxhunywa kalula kwikhompyutha noma ikhadi lokutholwa kwedatha.
3. Isinxephezelo sephutha ledijithali
Enye inzuzo yesiginali yokuphuma yedijithali ukuthi i-microprocessor ngaphakathi kwe-Digital Pressure Sensor nayo ingasetshenziswa ukuze uhlole kahle inzwa yengcindezi yokucindezela kanye namaphoyinti okushisa. Cishe wonke amaphutha e-linearity aqediwe.
4. Sebenzisa ubuchwepheshe obuphindaphindekayo futhi obuzinzile
Kodwa-ke, ukunemba kokugcina kwenzwa yokungcwaba yedijithali kuzohlala kukhawulelwe yi-hysteresis kanye nokuphindaphindwa kobuchwepheshe bezinzwa obusetshenzisiwe. Izici ze-hysteresis kanye nokuphindaphindeka azilindelwe kakhulu futhi akukulula ukwenza uphawu.
Ngakho-ke, okukhishwa kwedijithali kunganikeza isibonakaliso esinembile kunazo zonke sohlobo oluthile lwezinzwa, kepha kufanele lusetshenziswe ngokubambisana nobuchwepheshe obuzinzile obuzinzile obuphansi obuphansi kakhulu futhi buphindeke. Unembe ngempela empilweni yayo.
