Ngoku kuxhaphake ngakumbi ukusebenzisa i-elektronikiizikali zelori. Ngokumalunga nokulungiswa kunye nokugcinwa ngokubanzi kwezikali zelori zombane/ibhulorho yokulinganisa, masithethe ngolu lwazi lulandelayo njengomthengisi webhulorho enobunzima:
Isikali selori ye-elektroniki ikakhulu yenziwe ngamacandelo amathathu: i-loadcell, ulwakhiwo kunye nesekethe. Ukuchaneka kuvela kwi-1/1500 ukuya kwi-1/10000 okanye ngaphantsi. Ukusetyenziswa kwe-double integral A / D ukuguqulwa kwesekethe kunokuhlangabezana neemfuno zokuchaneka kwaye kunenzuzo yobuchule obunamandla bokuchasana nokuphazamiseka kunye neendleko eziphantsi. Ekuphunyezweni kwemimiselo ye-metrology kazwelonke, iimpazamo zesikali selori ye-elektroniki ngokwayo kunye neempazamo ezongezelelweyo ezisetyenziswayo yimiba ekufuneka abavelisi kunye nabasebenzisi banikele ingqalelo kuyo.
Okokuqala, indlela yokunciphisa iimpazamo kuyilo kunye nokuveliswa kwe-weighbridge ye-elektroniki:
1. Isiqinisekiso sezalathi zobugcisa ze-loadcell
Isitshixo sokuqinisekisa umgangatho wesikali selori ye-elektroniki ukukhetha ii-loadcells ezinezalathisi ezahlukeneyo zobugcisa ezihlangabezana neemfuno zokuchaneka. I-linearity, i-creep, i-coefficient yokushisa engekho umthwalo kunye ne-sensitivity yeqondo lokushisa zizibonakaliso ezibalulekileyo ze-loadcells. Kwibhetshi nganye yee-loadcells, ukuhlolwa kweesampuli kunye novavanyo oluphezulu noluphantsi lobushushu kufuneka lwenziwe ngokuhambelana nezinga lesampulu elifunwa yimigangatho kazwelonke efanelekileyo.
2. Iqondo lomlinganiso wesekethe yesikali selori ye-elektroniki
Uhlalutyo lwethiyori kunye novavanyo lungqina ukuba i-coefficient yobushushu bokumelana nokufakwa kweamplifier kunye nokumelana nempendulo zizinto ezibalulekileyo ezichaphazela i-coefficient yobushushu be-electronic coefficients sensitivity, kunye nesixhobo sokumelana nefilimu yentsimbi enomlinganiso wobushushu we-5 × 10-6. kufuneka kukhethwe. Uvavanyo lobushushu obuphezulu kufuneka lwenziwe kwisikali ngasinye selori ye-elektroniki eveliswayo. Kwezinye iimveliso ezinomlinganiselo omncinci we-coefficient yokushisa ngaphandle kokunyamezela, i-resistors yefilimu yensimbi ene-coefficient yokushisa engaphantsi kwe-25 × 10-6 ingasetyenziselwa ukubuyisela. Ngexesha elifanayo novavanyo oluphezulu lweqondo lokushisa, imveliso yayiphantsi kokuguga kweqondo lokushisa ukuphucula ukuzinza kwemveliso.
3. Imbuyekezo engeyiyo yomgca wesikali selori ye-elektroniki
Phantsi kweemeko ezifanelekileyo, ubungakanani bedijithali yesikali selori ye-elektroniki emva koguqulo lwe-analog ukuya kwidijithali kunye nobunzima obubekwe kwisikali selori ye-elektroniki kufuneka bungqamane. Xa usenza ulungelelwaniso oluchanekileyo ngexesha lenkqubo yokuvelisa, sebenzisa inkqubo yangaphakathi yekhompyuter yokulinganisa inqaku elinye. Bala ukuthambeka phakathi kwenani kunye nobunzima ngokomgca othe ngqo ofanelekileyo kwaye uwugcine kwinkumbulo. Oku akunako ukoyisa imposiso engeyiyo yomgca eyenziwe sisiva kunye nesihlanganisi. Ukusebenzisa i-multi-point correction, ukusebenzisa imigca ethe tye emininzi ukuqikelela igophe ngokufanelekileyo kunciphisa impazamo engeyiyo yomgca ngaphandle kokunyusa ixabiso le-hardware. Ngokomzekelo, isikali selori ye-elektroniki kunye ne-1 / 3000 ngokuchanekileyo ithatha ukulinganisa kwe-3-point, kunye nesikali selori ye-elektroniki kunye ne-1 / 5000 echanekileyo ithatha i-5-point calibration.
