Izinzwa zoxinzelelo zihlala zilinganiswa kwaye zichazwe ziiparameter ezininzi ngokubanzi. Ukuqonda ngokukhawuleza iinkcukacha ezisisiseko kuya kuba luncedo kakhulu kwinkqubo yokufumana okanye ukukhetha inzwa efanelekileyo. Kufuneka kuqatshelwe ukuba iinkcukacha zeZixhobo zinokuhluka phakathi kwabavelisi okanye kuxhomekeke kwiintlobo zezinto zenzwa ezisetyenzisiweyo.
★ Uhlobo loxinzelelo – uhlobo loxinzelelo olulinganisiweyo oluyilwe yi-sensor. Iindlela eziqhelekileyo zihlala ziquka i-gauge, i-absolute, i-sealed, i-vacuum, i-negative kunye ne-differential pressure.
★ Uluhlu loxinzelelo olusebenzayo – uluhlu lokulinganisa uxinzelelo oluqhelekileyo lokusebenza lwebhodi yesekethe ukuvelisa isiphumo sesignali esihambelanayo.
★ Uxinzelelo oluphezulu kakhulu – isibonelelo esiphezulu sokufunda sokuba isixhobo sinokusebenza ngokuzinzileyo ngaphandle kokulimaza itshiphu yesensa. Ukudlula umda kunokukhokelela ekungasebenzi kakuhle kwesixhobo okanye ekuwohlokeni kokuchaneka kwaso.
★ Isikali esipheleleyo – ubude ukusuka kuxinzelelo oluyi-zero ukuya kuxinzelelo lokulinganisa oluphezulu.
★ Uhlobo lokukhupha – Uhlobo kunye noluhlu lokukhupha isignali, ngokuqhelekileyo yi-milliampere okanye i-voltage. Iindlela zonxibelelwano ezikrelekrele ezifana ne-HART kunye ne-RS-485 ziya zithandwa kakhulu.
★ Umbane – Umbane onika amandla isixhobo esimelwe yi-volt direct current/volt alternating current yenombolo emiselweyo okanye uluhlu olwamkelekileyo. Umzekelo, i-24VDC(12~36V).
★ Ukuchaneka – ukuphambuka phakathi kokufunda kunye nexabiso loxinzelelo lokwenyani elimelwe yipesenti yesikali esipheleleyo. Ukulinganiswa kwefektri kunye nokulungiswa kobushushu kunokunceda ukuvavanya nokuphucula ukuchaneka kwesixhobo.
★ Isisombululo – umahluko omncinci kakhulu obonakalayo kwisignali yesiphumo.
★ Uzinzo – ukushukuma kancinci kancinci ngokuhamba kwexesha kwimeko yokulinganisa yesixhobo sokudlulisa.
★ Ubushushu bokusebenza – uluhlu lobushushu besixhobo esiyilelwe ukuba sisebenze ngokufanelekileyo kwaye sikhuphe ukufundwa okuthembekileyo. Ukusebenza rhoqo ngesixhobo esingaphezulu kwemida yobushushu kunokonakalisa kakhulu indawo emanzi.
