Izinzwa zokucindezela zivame ukulinganiswa futhi zichazwe ngamapharamitha ambalwa ajwayelekile. Ukugcina ukuqonda okusheshayo kokucaciswa okuyisisekelo kuzosiza kakhulu inqubo yokuthola noma ukukhetha inzwa efanele. Kufanele kuqashelwe ukuthi ukucaciswa Kwezinsimbi kungahluka phakathi kwabakhiqizi noma kuye ngezinhlobo ze-elementi yenzwa esetshenzisiwe.
★ Uhlobo lokucindezela - uhlobo lokucindezela okulinganiselwe inzwa eyenzelwe ukusebenza. Okukhethwa kukho okujwayelekile kuvame ukubandakanya igeji, i-absolute, ivalwe, i-vacuum, ingcindezi engemihle kanye nomehluko.
★ Uhla lwengcindezi yokusebenza – uhla lokulinganisa ingcindezi yokusebenza evamile yebhodi lesifunda ukuze kukhiqizwe umphumela wesignali ohambisanayo.
★ Ubukhulu bengcindezi yokugcwala ngokweqile - isilinganiso esiphezulu sokufunda ithuluzi elingasebenza ngokuzinzile ngaphandle kokulimaza i-chip yezinzwa. Ukweqa umkhawulo kungase kubangele ukungasebenzi kahle kwezinsimbi okungenakulungiseka noma ukonakala kokunemba.
★ Isikali esigcwele - ibanga ukusuka ku-zero kuya kumfutho wokulinganisa omkhulu.
★ Uhlobo lokukhiphayo - Imvelo nobubanzi bokukhishwa kwesignali, ngokuvamile kufanele kube i-milliampere noma i-voltage. Izinketho zokuxhumana ezihlakaniphile njenge-HART ne-RS-485 seziba umkhuba odumile.
★ Ukunikezwa kwamandla kagesi - Ukunikezwa kwamandla kagesi ukuze kunikwe amandla ithuluzi elimelelwa i-volt eqondile yamanje/volt eshintshashintshayo yamanje yenombolo engaguquki noma ububanzi obamukelekayo. Isb 24VDC(12~36V).
★ Ukunemba – ukuphambuka phakathi kokufunda kanye nenani langempela lokucindezela elimelelwa yiphesenti lesikali esigcwele. Ukulinganiswa kwefektri kanye nokunciphisa izinga lokushisa kungasiza ekuhloleni nasekuthuthukiseni ukunemba kwedivayisi.
★ Ukulungiswa - umehluko omncane obonakalayo kusignali yokuphumayo.
★ Ukuzinza - ukukhukhuleka kancane kancane ngokuhamba kwesikhathi esimweni esilinganiselwe sesithumeli.
★ Izinga lokushisa elisebenzayo - izinga lokushisa eliphakathi nendawo lapho idivayisi yakhelwe ukuthi isebenze kahle futhi ikhiphe ukufundwa okuthembekile. Ukusebenza njalo ngesilinganiso esingaphezu kwesilinganiso sokushisa kungalimaza ingxenye emanzisiwe kakhulu.
I-Shanghai WangYuan Instruments of Measurement Co., Ltd. iyibhizinisi laseShayina lobuchwepheshe obuphezulu eligxile kubuchwepheshe bokulawula inqubo yezimboni kanye nemikhiqizo iminyaka engaphezu kwamashumi amabili. Singanikeza okupheleleimigqa yomkhiqizoyezidlulisi zengcindezi ngokuhambisana nezimfuno zamakhasimende kumapharamitha angenhla.
