Amageyiji obukhulu angamathuluzi anamandla okulinganisa ubukhulu bezinto ezahlukahlukene, kodwa ukusebenza kwawo kuncike ezimweni ezithile. Ukuqonda izimo lapho la mathuluzi engafaneleki kubalulekile ukuze kugwenywe izilinganiso ezinganembile nemiphumela engathembekile.
Umkhawulo owodwa oyinhloko uvela lapho kusetshenzwa ngezinto ezingahambisani nomgomo wokulinganisa wegeji. Isibonelo, amageji obukhulu be-ultrasonic athembele ekudlulisweni nasekubonisweni kwamagagasi e-ultrasonic ngezinto. Uma izinto zinokumuncwa okuphezulu kakhulu kwamagagasi e-ultrasonic, njengezinto ezinezimbobo eziningi njenge-aerogels noma izinhlobo ezithile zamagwebu amunca umsindo, amagagasi e-ultrasonic azoncipha kakhulu noma angene ngokuphelele ngaphambi kokufinyelela endaweni engemuva ukuze kuboniswe. Ezimweni ezinjalo, igeji ayikwazi ukuthola izimpawu ze-echo ezidingekayo ukuze kubalwe ukujiya ngokunembile, okwenza kungasebenzi. Ngokufanayo, amageji obukhulu obusekelwe ku-electromagnetic, asebenza ngesimiso sokungeniswa kwe-electromagnetic noma ama-eddy currents, awafaneleki ezintweni ezingezona ezokuhambisa umoya. Njengoba izinto ezingezona ezokuhambisa umoya zingasebenzisani nezinsimu ze-electromagnetic ngendlela edingekayo, la mageji awakwazi ukunikeza izilinganiso zobukhulu ezinengqondo.
Esinye isimo lapho amageyiji okujiya engasebenzi khona yilapho ubuso bezinto busesimweni esibi kakhulu. Izindawo ezimageyiji, ezingalingani, noma ezibolile kakhulu zingaba yizinselele ezinkulu. Kumageyiji okujiya ohlobo lokuxhumana, njenge-micrometer noma amageyiji okudayela, ubuso obungalingani kwenza kube nzima ukuqinisekisa ukuthintana nokuqondana okufanele, okuholela ekufundweni okungahambisani nokunganembile. Ngisho nakumageyiji angathintani njenge-laser noma amageyiji okujiya okubonakalayo, ubuso obungajwayelekile kakhulu bungabangela ukuthi umsebe wokulinganisa uhlakazeke noma ubonakale ngezindlela ezingalindelekile, kuvimbele ukunqunywa okunembile kobukhulu. Ngaphezu kwalokho, uma ubuso bungcoliswe ungqimba olujiyile lokungcola, amafutha, noma ezinye izinto, kungaphazamisa inqubo yokulinganisa. Isibonelo, esimweni samageyiji e-ultrasonic, ubuso obungcolile bungaphazamisa ukuhlangana phakathi kwe-transducer nezinto, kuthinte ukudluliselwa kwamagagasi e-ultrasonic futhi kuholele ekulinganisweni okunganembile.
Izimo zemvelo nazo zidlala indima ebalulekile ekusetshenzisweni kwama-geuge obukhulu. Izindawo ezinokushisa okuphezulu zingadala izinkinga ezinhlotsheni eziningi zama-gauge. Amanye ama-gauge, ikakhulukazi lawo anezingxenye ze-elekthronikhi noma izingxenye zemishini, angase abhekane nokwanda kokushisa noma ukuwohloka kwezinto emazingeni okushisa aphezulu, okushintsha ukulinganiswa nokunemba kwazo. Isibonelo, izakhi ze-piezoelectric kuma-transducer e-ultrasonic zingalahlekelwa ukusebenza kwazo noma zishintshe izici zazo zokusebenza uma zivezwa ekushiseni okuphezulu isikhathi eside. Ezimweni zokushisa okuphansi kakhulu, izinto zingase zibe buthaka noma zishintshe izakhiwo zazo zomzimba, okungathinta nemiphumela yokulinganisa. Ngaphezu kwalokho, ezindaweni ezinomswakama ophezulu, umswakama ungalimaza izingxenye zangaphakathi zama-geuge obukhulu be-elekthronikhi noma uthinte ukuhlanganiswa kwama-geuge e-ultrasonic, okwenza zingathembeki.
Uma i-geometry yento ezolinganiswa iyinkimbinkimbi noma ingafinyeleleki, amageyiji okujiya angase angakwazi ukusebenza kahle. Isibonelo, ukukala ukujiya kwezingxenye zangaphakathi esakhiweni esiyinkimbinkimbi, esivalekile lapho igeyiji ingakwazi ukufinyelela khona iphuzu lokulinganisa akunakwenzeka. Futhi, ezintweni ezinezingxenye ezincane kakhulu noma ezincane eziphambeneyo ezincane kunobubanzi bokulinganisa obuncane begeyiji, ukunqunywa kobukhulu obunembile kuba yinto engenakwenzeka. Amanye amageyiji okujiya adinga indawo ethile eyisicaba nezinzile yokulinganisa, futhi uma into inesimo esiyingqayizivele esingahlangabezani nalezi zidingo, igeyiji ayikwazi ukusetshenziswa ngempumelelo.
Ekuphetheni, nakuba amageyiji okujiya eyithuluzi eliwusizo lokusetshenziswa okubanzi, kunezimo eziningi lapho zingasetshenziswa khona. Lokhu kufaka phakathi ukungalingani kwezinto, izimo eziphezulu kakhulu, izici zemvelo ezimbi, kanye namajiyomethri ayinkimbinkimbi noma angafinyeleleki. Ukuqaphela le mikhawulo kubalulekile ekukhetheni izindlela zokulinganisa ezifanele nokuqinisekisa ukuthembeka kwedatha ehlobene nokujiya.
