Imilinganiselo yolawulo lwempazamo yokulinganisa
Ngokwenza, isizathu sokuba kutheni impazamo yokulinganisa isikali, ngaphezu kwempembelelo yomgangatho wayo, kunye nokusebenza kwabasebenzi, inqanaba lobugcisa, njl.Okokuqala, umgangatho obanzi wabasebenzi bokuhlola uchaphazela ukuchaneka kokuhlolwa kwesikali, kumsebenzi wokutshekisha ukuba abasebenzi abazange basebenze ngokuhambelana neenkqubo eziqhelekileyo zokuhlola i-metrological, kulula ukukhokelela kumlinganiselo wesikali. imposiso yokujonga.Ngokomzekelo, xa uhlola ukusebenza kwe-push kunye nokulinganisela kwezikali, kulula kakhulu ukuba abahloli bangayihoyi ukuguquguquka kokujonga izikali ezingenanto.Okwesibini, izikali zisetyenziselwa ukulinganisa ubunzima bezinto, kwaye ngokusekelwe kwinqanaba lokusebenza, zinokwahlulwa zibe zilawulo zombane, iiseli zomthwalo, abalawuli bokubonisa ubunzima, njl. Ngophuhliso lwenzululwazi yezentlalo kunye nobuchwepheshe, izikali zisetyenziswa kakhulu. yokulinganisa ubunzima bezinto.Ngophuhliso lwenzululwazi yezentlalo kunye nethekhinoloji, inkqubo yokusebenza kwesikali iye yatshintsha kakhulu, kwaye yaphuhliswa ukusuka kumlinganiselo wemveli ukuya kwimodyuli kunye nobukrelekrele, kodwa ngenxa yokuba itekhnoloji yolawulo kufuneka iphuculwe, kusekho ukutenxa okukhulu kwinqanaba lokulinganisa. , uluhlu olusemgangathweni, njalo njalo.
Ukulinganisa izikali zombane, ngokuqhelekileyo zisetyenziswa kwiimarike zorhwebo kunye nezinye iindawo, ezibandakanya amanqaku amathandathu afana ne-5 g, 10 g, 20 g, ehambelana nempazamo evumelekileyo ye-± 0.1 g, ± 0.5 g, njl. xa usenza umlinganiselo kunye nokulinganisa izikali ze-elektroniki, abasebenzi bokulinganisa kufuneka bafake ukubaluleka okukhulu kwindawo yokulinganisa kunye nexabiso lempazamo elivumelekileyo, kunye neerekhodi ezicacileyo zedatha yobunzima obuqhelekileyo ngexesha lokulinganisa, ezinokulinganiswa ngempazamo yokulinganisa Izikali ze-elektroniki zinokulawulwa kwimida efanelekileyo.Oku kunokulawula impazamo yomlinganiselo wezikali zombane ngaphakathi koluhlu olufanelekileyo.Ngelo xesha, igosa eliqinisekisayo kufuneka ligcwalise "iSatifikethi seSatifikethi" ngokufanelekileyo kunye nemeko ye-electronic scale, kwaye ingenise isatifikethi kwisebe elinobuchule ukuze lihlolwe, elinokuphucula umphumo wokulinganisa umlinganiselo we-elektroniki.Okwangoku, kwinkqubo yokulinganisa okuphindaphindiweyo, ukuze kuphuculwe ukuchaneka kweziphumo zokulinganisa, abasebenzi bokulinganisa kufuneka babeke izixhobo zokulinganisa umlinganiselo we-elektroniki kwiimeko ezahlukeneyo zokulinganisa, kwaye emva koko benze umsebenzi omhle wokurekhoda idatha yokulinganisa, leyo. inokuphucula nokuchaneka kweziphumo zolungelelwaniso.
Umlinganiselo wophuhliso lwexesha elizayo loshishino lokulinganisa
Izikali zokulinganisa ziya kuguqulwa ukusuka kwisikali sombane we-analog ukuya kwizikali zombane zedijithali, kunye nophuhliso lwetekhnoloji ye-microelectronics, inkqubo yokuvelisa izivamvo zedijithali igqibelele ngakumbi, izikali zombane ze-analog ziya kutshintshwa ngempumelelo zizikali zombane zedijithali, izikali zombane zedijithali ngenxa ukuthembeka kweziphumo ezinamandla, ezilungileyo zokulinganisa, ngoko kuya kubonwa yimarike.Izikali ezingezizo ezizenzekelayo nazo ziya kuqhubeka nokuphuhlisa izikali ezizenzekelayo, kwaye isikali, isikali esisodwa siya kutshintshwa zizixhobo ezizenzekelayo, iinkqubo zokulinganisa.Ngophuhliso loshishino lwesikali sokulinganisa, ukusetyenziswa kweTshayina kwezikali zokulinganisa akusengomsebenzi omnye, kwaye kudityaniswe kulawulo, ulawulo kunye nokubeka iliso, njl. njl., amashishini okuvelisa nawo aya kwenza ukuveliswa kwezixhobo zokuhambisa kunye nokugcina.Ngokuphathelele itekhnoloji yokulinganisa iya kutshintsha ukusuka kwi-static yendabuko ukuya kubunzima obuguqukayo.Umlinganiselo ukusuka kumlinganiselo wokulinganisa i-analog ukuya kumlinganiselo wedijithali, umlinganiselo weparameter enye iya kuba yi-multi-parameter yokulinganisa, kunye nokusebenza kobugcisa bomlinganiselo kuya kuba ngokubhekiselele kwicala lozinzo oluqinileyo, ukuchaneka okuphezulu kunye nezinga elihle lophuhliso.Ukongeza, izikali zokulinganisa ziya kuthambekela ekwenzeni i-miniaturization, imodyuli, ukudibanisa kunye nesikhokelo esikrelekrele.Ngokusetyenziswa kwezikali zokulinganisa, ukuphuculwa, izixhobo zokulinganisa ziya kuqhubeka ukunciphisa ubungakanani, ukuphakama kuya kuncitshiswa, kodwa kubonisa kwakhona indibaniselwano yokwahlukana kwemodyuli.Ngaphantsi kwalo mkhwa, ukuthembeka kunye nokuguquguquka kweemveliso kuya kuphuculwa kakhulu, kwaye umgangatho wemveliso kunye nesiphumo seemveliso zesikali ziya kuqiniswa.
