Isidlulisi sokuhluka kwengcindezi siyinzwa ejwayelekile, enezicelo ezithile ezimbonini ezahlukahlukene futhi futhi iyinzwa ejwayelekile. Ngakho-ke iyini umehluko wokudlulisa wengcindezi futhi uyini umgomo osebenzayo wokudlulisa umehluko wokucindezela? Lapha sizokwethula kumgomo wokusebenza womdluliseli wokudlulisa umehluko wengcindezi.
E-LefooUmkhiqizi wokudlulisa ingcindezi, Ngokuvamile ingcindezi ingaphansi noma ilingana nengcindezi ye-50 kPa ibizwa nge-micro-cindezi; umehluko phakathi kwalezi zingcindezi ezimbili ungaphansi noma ulingana nengcindezi yokuhlukanisa engu-50kPa ibizwa ngengcindezi encane, uhla lwengcindezi lwe-20 kPa noma ngaphansi, ngokukhishwa okubizwa nge-micro-differential pressure transmitter.
(A) isidlulisi sokuhlukanisa kwengcindezi emincane ngokwezindawo ezahlukahlukene zokulinganisa sihlukaniswe.
1. Isidlulisi sokucindezela kwebanga lezimboni umoya wengcindezi encane yokuhlukanisa, isilinganiso somoya.
2. I-Isidlulisi sokucindezela okuhlukileFuthi ukulinganisa akukhawulelwe.
(B) izici zokudlulisa ingcindezi emincane yokuhluka
1. Ingalinganisa ku-60Pa ibanga, nokuqinisekisa ukuthi izinkomba zokusebenza.
2. I-LCD noma i-LED ngokuzikhethela, kulula ukuthi abasebenzisi basebenzise kusayithi.
3. Amanje, okukhipha amandla okuzikhethela, ukudlulisa ingcindezi emibili kungaba ngomsebenzi we-HART.
Isidlulisi sokucindezela okuhlukile ngokuvamile sihlukaniswe ngamabanga amaningi, Ikhodi yebanga elijwayelekile 2 kuya ku-9, lapho ububanzi 2 bumele ingcindezi emincane yokuhlukanisa i-1.6 KPa; olunye uhla lwesi-3 lumele u-0 kuye ku-7KPa, ibanga 4 limele i-40KPa, ibanga lesi-5 limele i-180 KPa, njalonjalo; Ngoba uhla lwezidlulisi zokuhlukanisa kwengcindezi namabhodi wesifunda kunzima ukufeza, ngakho-ke ihlukaniswe.
Isidlulisi sokuhlukanisa kwengcindezi silinganise isilinganiso sezingcindezi ezimbili egumbini lokucindezela eliphakeme neliphansi, ukusebenza ngento ye- δ (i. e., into ebucayi) ezinhlangothini zombili ze-diaphragm yokuhlukanisa, ngeshidi lokuhlukanisa kanye noketshezi lokugcwalisa ngaphakathi kwento edluliselwe ezinhlangothini zombili ze-diaphragm yokulinganisa. I-diaphragm yokulinganisa nama-electrode eshidini lokuvikela izinhlangothi zombili ngalinye lakha i-capacitor.
Lapho ingcindezi ezinhlangothini zombili ingafani, okuholele ekufudusweni kwe-diaphragm yokulinganisa, umehluko wokufuduka nengcindezi ulingana, ngakho-ke amandla ezinhlangothini zombili akulingani, ngokusebenzisa isixhumanisi sokuxhumanisa nokudambisa, kuguqulwe saba isiginali ngokulingana nengcindezi. Umgomo osebenzayo wokudlulisa ingcindezi kanye nomdlulisi wengcindezi ophelele uyafana nokwehlukanisa kwengcindezi, umehluko ukuthi ingcindezi yekamelo eliphansi ingcindezi yomkhathi noma i-vacuum.
I-a / d iguqula i-demodulator yamanje ibe yisiginali yedijithali, inani elisetshenziswa yi-microprocessor ukunquma inani lokufaka kwengcindezi. I-microprocessor ilawula ukusebenza komthumeli.
Ngaphezu kwalokho, yenza umgqa wezinzwa, ingasebenzisa kabusha uhla lokulinganisa, ukuguqulwa kweyunithi yobunjiniyela, ukunciphisa, isikwele esivulekile, Ukunciphisa inzwa neminye imisebenzi, kanye nokuxilongwa nokuxhumana kwedijithali.
