Manje sekuya ngokuya kuvame ukusebenzisa i-electronicizikali zamaloli. Mayelana nokulungiswa nokugcinwa okuvamile kwezikali/ibhuloho lika-elekthronikhi, ake sikhulume nge-informaton elandelayo njengomnikezeli webhuloho elinesisindo:
Isikali samaloli e-elekthronikhi sakhiwe ikakhulukazi izingxenye ezintathu: i-loadcell, isakhiwo kanye nesekhethi. Ukunemba kusuka ku-1/1500 kuye ku-1/10000 noma ngaphansi. Ukusetshenziswa kwesekethe yokuguqula ye-A/D ebalulekile ephindwe kabili kungahlangabezana nezidingo zokunemba futhi kunezinzuzo zekhono eliqinile lokulwa nokuphazamiseka kanye nezindleko eziphansi. Ekusetshenzisweni kwemithetho ye-metrology kazwelonke, amaphutha esikali samaloli e-elekthronikhi ngokwaso kanye namaphutha engeziwe asetshenziswayo yizindaba okumele abakhiqizi nabasebenzisi bazinake.
Okokuqala, indlela yokunciphisa amaphutha ekwakhiweni nasekukhiqizeni ibhuloho lokukala le-elekthronikhi:
1. Isiqinisekiso sezinkomba zobuchwepheshe ze-loadcell
Kuwukhiye wokuqinisekisa ikhwalithi yesikali samaloli e-elekthronikhi ukukhetha ama-loadcell anezinkomba ezihlukahlukene zobuchwepheshe ezihlangabezana nezidingo zokunemba. I-linearity, i-creep, i-coefficient yokushisa engalayishiwe kanye ne-coefficient yezinga lokushisa lokuzwela yizinkomba ezibalulekile zama-loadcells. Eqeqebeni ngalinye lama-loadcells, ukuhlolwa kwesampula kanye nokuhlolwa kwezinga lokushisa eliphezulu neliphansi kufanele kwenziwe ngokuvumelana nesilinganiso samasampula esidingwa izindinganiso zikazwelonke ezifanele.
2. I-temperature coefficient yesekethe yesikali samaloli kagesi
Ukuhlaziywa kwethiyori nokuhlola kufakazela ukuthi i-coefficient yezinga lokushisa lokumelana okokufaka kwe-amplifier yokufaka kanye nokumelana nempendulo yizici ezibalulekile ezithinta i-coefficient yokushisa yokuzwela kwesikali seloli ye-elekthronikhi, kanye nokumelana nefilimu yensimbi ene-coefficient yokushisa engu-5 × 10-6. kufanele kukhethwe. Ukuhlolwa kwezinga lokushisa eliphezulu kufanele kwenziwe kuzo zonke izikali zamaloli e-elekthronikhi ezikhiqizwayo. Kweminye imikhiqizo enenani elincane le-coefficient yokushisa engaphandle kokubekezelelana, izithasiselo zefilimu zensimbi ezine-coefficient yokushisa engaphansi kuka-25 × 10-6 zingasetshenziswa ukunxephezela. Ngesikhathi esifanayo nokuhlolwa kokushisa okuphezulu, umkhiqizo wawungaphansi kokuguga okushisa ukuze kuthuthukiswe ukuzinza komkhiqizo.
3. Isinxephezelo esingaqondile sesikali samaloli kagesi
Ngaphansi kwezimo ezikahle, inani ledijithali lesikali seloli le-elekthronikhi ngemva kokuguqulwa kwe-analog kuya kudijithali kanye nesisindo esibekwe esikalini seloli le-elekthronikhi kufanele sihambisane. Lapho wenza ukulinganisa okunembayo phakathi nenqubo yokukhiqiza, sebenzisa uhlelo lwangaphakathi lwekhompuyutha ukulinganisa iphuzu elilodwa. Bala ukuthambeka phakathi kwenombolo nesisindo ngokomugqa oqondile okahle bese uwugcina kumemori. Lokhu akukwazi ukunqoba iphutha elingelona umugqa elikhiqizwe inzwa nesihlanganisi. Ukusebenzisa ukulungisa amaphuzu amaningi, ukusebenzisa imigqa eqondile eminingi ukulinganisa ijika kunciphisa ngempumelelo iphutha elingelona umugqa ngaphandle kokwenyusa izindleko zehadiwe. Isibonelo, isikali seloli le-elekthronikhi esinokunemba okungu-1/3000 sithatha ukulinganisa kwamaphuzu angu-3, futhi isikali seloli le-elekthronikhi esinokunemba okungu-1/5000 sithatha ukulinganisa kwamaphoyinti angu-5.
