Izinzwa zokucindezela zivame ukulinganiswa futhi zichazwe yimingcele eminingana ejwayelekile. Ukuqonda okusheshayo kwemininingwane eyisisekelo kuzosiza kakhulu enkambisweni yokuthola noma yokukhetha inzwa efanele. Kufanele kuqashelwe ukuthi imininingwane ye-Instrumentations ingahluka phakathi kwabakhiqizi noma kuye ngezinhlobo zesici senzwa esisetshenzisiwe.
★ Uhlobo lokucindezela – uhlobo lokucindezela okulinganisiwe inzwa eyenzelwe ukusebenza. Izinketho ezivamile zivame ukufaka i-gauge, i-absolute, i-sealed, i-vacuum, i-negative kanye ne-differential pressure.
★ Uhla lwengcindezi yokusebenza – uhla lokulinganisa ingcindezi yokusebenza evamile yebhodi lesifunda ukuze kukhiqizwe umphumela wesignali ohambisanayo.
★ Ukucindezela okukhulu kakhulu – isilinganiso esiphezulu sokufunda sokuthi ithuluzi lingasebenza kahle ngaphandle kokulimaza i-chip yesensa. Ukudlula umkhawulo kungaholela ekungasebenzi kahle kwezinsimbi zomculo noma ekuwohlokeni kokunemba.
★ Isikali esigcwele – ububanzi kusukela ekucindezelweni okungu-zero kuya ekucindezelweni okuphezulu kokulinganisa.
★ Uhlobo lokukhipha – Uhlobo kanye nobubanzi bokukhipha isignali, ngokuvamile kube yi-milliampere noma i-voltage. Izinketho zokuxhumana ezihlakaniphile njenge-HART ne-RS-485 seziba yindlela ethandwayo.
★ Ukunikezwa kwamandla – Ukunikezwa kwamandla kagesi okuphakamisa ithuluzi elimelelwa yi-volt direct current/volt alternating current yenombolo ehleliwe noma ububanzi obamukelekayo. Isib. 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.
★ Isixazululo – umehluko omncane kakhulu otholakalayo kusignali yokukhipha.
★ Ukuzinza – ukuzulazula kancane kancane ngokuhamba kwesikhathi esimweni esilinganisiwe sesithumeli.
★ Izinga lokushisa lokusebenza – izinga lokushisa lendawo yokusebenzela lapho idivayisi yakhelwe ukusebenza kahle futhi ikhiphe ukufundwa okuthembekile. Ukusebenza njalo ngendawo yokusebenzela ngale kwemingcele yokushisa kungalimaza kakhulu ingxenye emanzi.
I-Shanghai WangYuan Instruments of Measurement Co., Ltd. iyinkampani yaseShayina enobuchwepheshe obuphezulu egxile kubuchwepheshe bokulawula izinqubo zezimboni kanye nemikhiqizo iminyaka engaphezu kwamashumi amabili. Singahlinzeka ngokupheleleimigqa yomkhiqizoyama-pressure transmitter ngokuhambisana nezidingo zamakhasimende kumapharamitha angenhla.
