Ukuchaneka kwe-gauge yoxinzelelo kubonakaliswa ngokuyinhloko kwinqanaba lokuchaneka kwayo.
Ibakala lokuchaneka liyipharamitha ephambili yokulinganisa uxinzelelo, ebonisa ukuchaneka kweziphumo zayo zokulinganisa. Ngokuqhelekileyo, ibakala lokuchaneka limelwe linani, elifana no-1.0, 1.6, okanye 2.5. Eli nani limele eyona mpazamo inkulu evumelekileyo yegeyiji yoxinzelelo njengepesenti yoluhlu lokulinganisa.
Ngokomzekelo, ukuba i-Class 1.0 ye-pressure gauge inoluhlu lwe-0-10 MPa, impazamo yayo ephezulu evumelekileyo luluhlu (10 MPa) luphindwe ngepesenti ehambelana nebakala lokuchaneka (1.0%), eliyi-0.1 MPa. Oku kuthetha ukuba phezu koluhlu lonke lokulinganisa, impazamo yokulinganisa le gauge yoxinzelelo ayiyi kudlula ± 0.1 MPa.
Ibakala lokuchaneka komlinganiselo woxinzelelo lichongwa ngexesha loyilo kunye nenkqubo yokuvelisa. Ixhomekeke ikakhulu kwizinto ezininzi, kubandakanywa ukwakheka kwegeyiji, iimpawu zento enwebekayo, ukuchaneka kwendlela yokuhambisa, kunye nenkqubo yokwenziwa kwemveliso. -Iigeyiji zoxinzelelo oluchanekileyo ziqhele ukusebenzisa izinto ezilastiki ezichanekileyo, njengeityhubhu zeBourdon ezenziwe ngealloyi ezikhethekileyo. Ezi zinto zibonelela ngeempawu ezizinzileyo nezichanekileyo, kwaye indlela yokuhambisa iyilwe kwaye yenziwe ngokuchaneka okuphezulu, oko kunciphisa iimpazamo zokulinganisa.
Inqanaba lokuchaneka liboniswa ngokuqhelekileyo kwi-dial gauge dial, mhlawumbi kwi-nameplate okanye kwindawo yokumakisha ehambelanayo. Oku kuvumela abasebenzisi ukuba bahlole ukuthembeka kokufunda uxinzelelo ngokusekelwe kwinqanaba lokuchaneka. Umzekelo, izicelo ezifuna{2}}umlinganiselo woxinizelelo oluchanekileyo oluphezulu, olufana nemifuniselo yenzululwazi kunye nolawulo oluphezulu{3}}loluchanekileyo lwenkqubo yoshishino, lufuna iigeyiji zoxinzelelo ezinamanqanaba aphezulu achanekileyo ukuqinisekisa idatha yomlinganiselo ochanekileyo.
Ngaphezu koko, ukuchaneka komlinganiselo woxinzelelo kunokuchaphazeleka kwindawo yokusebenza. Ngokomzekelo, ukuguquguquka kweqondo lokushisa kunokubangela ukuba i-elastic modulus ye-elastic element itshintshe, ichaphazela ukuchaneka komlinganiselo. Ngoko ke, kwizicelo ezifuna ukuchaneka okuphezulu kakhulu, kuyimfuneko ukuqwalasela imbuyekezo yeqondo lokushisa kunye namanye amanyathelo okugcina ukuchaneka kwe-pressure gauge.
