Ekusetshenzisweni kwe-instrumentation, ngaphansi kwezimo ezijwayelekile, ukusetshenziswa kwama-transmitter kuyinto ebanzi kakhulu futhi ejwayelekile, ehlukaniswe cishe yaba ama-pressure transmitters kanye nama-different pressure transmitters.Ama-transmitters avame ukusetshenziselwa ukukala ingcindezi, ingcindezi ehlukile, i-vacuum, izinga le-liquid, njll.
Ama-transmitters ahlukaniswe abe uhlelo lwezintambo ezimbili (isignali yamanje) kanye nesistimu yezintambo ezintathu (isignali ye-voltage).Ama-transmitter anezintambo ezimbili (isignali yamanje) avame kakhulu;kukhona abahlakaniphile nabangenangqondo, futhi bayanda abadlulisi abahlakaniphe kakhulu;ngaphezu kwalokho , Ngokusho isicelo, kukhona intrinsically ephephile uhlobo kanye nokuqhuma-ubufakazi uhlobo;lapho ukhetha uhlobo, kufanele wenze ukukhetha okuhambisanayo ngokwezidingo zakho.
1. Ukuhambisana kwendawo ehloliwe
Lapho ukhetha uhlobo, cabangela umthelela we-medium kusixhumi esibonakalayo sokucindezela kanye nezingxenye ezibucayi, ngaphandle kwalokho i-diaphragm yangaphandle izogqwala ngesikhathi esifushane ngesikhathi sokusetshenziswa, okungase kubangele ukugqwala kwemishini nokuphepha komuntu siqu, ngakho-ke ukukhetha kwezinto baluleke kakhulu .
2. Umthelela wezinga lokushisa eliphakathi nendawo nokushisa kwe-ambient emkhiqizweni
Izinga lokushisa lendawo elinganisiwe kanye nezinga lokushisa elizungezile kufanele kucatshangelwe lapho kukhethwa imodeli.Uma izinga lokushisa liphezulu kunesinxephezelo sezinga lokushisa lomkhiqizo ngokwawo, kulula ukubangela ukuthi idatha yokulinganisa umkhiqizo ikhukhuleke.I-transmitter kufanele ikhethwe ngokuya ngendawo yokusebenza yangempela ukuze kugwenywe izinga lokushisa elibangela umgogodla ozwela ukucindezela.Isilinganiso asinembile.
3. Ukukhethwa kwebanga lokucindezela
Isilinganiso sokucindezela kwesidlulisi somfutho kufanele sihambisane nesilinganiso sokucindezela kocingo lapho lusebenza.
4. ukukhethwa kwesixhumi esibonakalayo sokucindezela
Enqubweni yokukhetha, usayizi wentambo ofanele kufanele ukhethwe ngokuya ngosayizi wembobo yokucindezela wemishini yangempela esetshenzisiwe;
5. Ukukhethwa kwesixhumi esibonakalayo sikagesi
Lapho ukhetha imodeli, kuyadingeka ukuqinisekisa ukusetshenziswa kwezindlela zokuthola isignali kanye nezimo zezintambo ezisendaweni.Isignali yenzwa kufanele ixhunywe kusixhumi esibonakalayo sokutholwa komsebenzisi;khetha inzwa yokucindezela ene-interface elungile kagesi kanye nendlela yesignali.
6. Ukukhetha uhlobo lokucindezela
Ithuluzi elikala ukucindezela okuphelele libizwa ngokuthi i-absolute pressure gauge.Kumageji okucindezela okujwayelekile kwezimboni, umfutho wegeji uyalinganiswa, okungukuthi, umehluko wengcindezi phakathi kwengcindezi ephelele kanye nomfutho womoya.Uma ukucindezela okuphelele kukhulu kunokucindezela komkhathi, ukucindezela kwegeji elinganisiwe kuhle, okubizwa ngokuthi i-positive gauge pressure;lapho ukucindezela okuphelele kungaphansi komfutho womkhathi, umfutho wegeji olinganisiwe unegethivu, obizwa ngokuthi i-negative gauge pressure, okungukuthi, izinga le-vacuum.Ithuluzi elikala izinga le-vacuum libizwa ngokuthi i-vacuum gauge.
