Isebenza Kanjani I-Rosemount Pressure Transmitter?

Ama-Rosemount pressure transmitters aphakathi kwamadivayisi asetshenziswa kakhulu emhlabeni wezinsimbi zenqubo yezimboni. Aqashelwa ngokuthembeka kwawo kanye nokunemba ekukaleni uketshezi nomfutho wegesi ezimbonini ezihlukahlukene, ezifana nowoyela negesi, ezemithi, nokwelapha amanzi. Le bhulogi ihlinzeka ngokubheka okujulile kokuthi i-Rosemount pressure transmitter isebenza kanjani, iqinisekisa ukuthi ochwepheshe nonjiniyela bayayiqonda imigomo nezingxenye ezivumela laba bathumeli ukuthi basebenze ngempumelelo.

Yiziphi Izingxenye Eziyinhloko Ze-Rosemount Pressure Transmitter?

Ukuqonda izingxenye eziyinhloko ze-Rosemount pressure transmitter kubalulekile ukuze uqonde ukuthi idivayisi ikala kanjani ingcindezi futhi iyiguqule ibe isignali esebenzisekayo.

Imojuli yenzwa yokucindezela

Imojula yenzwa yokucindezela iyingxenye eyinhloko enesibopho sokuthola ingcindezi yoketshezi lwenqubo noma igesi. Ngokuvamile iqukethe inzwa ye-piezoresistive noma capacitive, esabela ezinguqukweni zengcindezi ngokushintsha izici zayo zikagesi. Inzwa ithola lolu shintsho bese iyiguqulela isignali kagesi.

I-Transmitter Electronics

I-transmitter electronics icubungula isignali eluhlaza evela kunzwa bese iyiguqulela ekuphumeni okujwayelekile, ngokuvamile okungu-4-20 mA noma iphrothokholi yedijithali efana ne-HART. Lo mjikelezo uvamise ukufaka isimo sesignali, ukuhlunga, nezigaba zokukhulisa ukuze kuqinisekiswe ukuthi okukhiphayo kokugcina kunembile futhi kuzinzile.

Ukuxhumana Kwezindlu Nezinqubo

Izindlu ze-transmitter zivikela izingxenye zangaphakathi ezindaweni ezinokhahlo. Ukuxhumana kwezinqubo kuxhumanisa isidluliseli epayipini noma emkhunjini, kuqinisekisa ukudluliswa okunembile nokuthembekile kwengcindezi yenqubo kwinzwa.

I-Rosemount Pressure Transmitter ikala kanjani futhi iyidlulisele kanjani idatha yokucindezela?

I-Rosemount pressure transmitter isebenza ngokulandelana kwezinyathelo ezibandakanya ukuzwa, ukucutshungulwa kwesignali, nokudluliswa kwedatha. Ngasinye salezi zinyathelo sidlala indima ebalulekile ekuqinisekiseni izilinganiso zokucindezela ezinembile.

Izwa Izinguquko Zengcindezi

Isicelo Sokucindezela: Uma ukucindezela kwenqubo kusetshenziswa kumojula yenzwa yokucindezela, into ezwayo ngaphakathi isabela kumandla omshini asetshenziswa uketshezi lwenqubo noma igesi.

Inzwa Impendulo: Kuye ngohlobo lwenzwa (i-piezoresistive noma i-capacitive), isici sokuzwa sishintsha umzimba. Ku-sensor ye-piezoresistive, ukumelana kuyashintsha, kuyilapho ku-sensor capacitive, i-capacitance iyahlukahluka ngenxa yokucindezela okusetshenzisiwe.

Ukukhiqizwa Kwesiginali Kagesi: Ukuguqulwa komshini kuhunyushwa kusignali kagesi, emele ubukhulu bengcindezi esetshenzisiwe.

Ukucubungula Okumaka

Isimo Sesignali: Isignali kagesi eluhlaza ifakwe esimweni ukuze ihlunge umsindo futhi ilungise izinga lesignali ukuze kuqhutshekwe nokucubungula.

Ukukhulisa nokuguqulwa: Isignali enesimo iyakhuliswa futhi iguqulelwe kufomu elifanele ukudluliselwa, ngokuvamile isignali yamanje engu-4-20 mA noma iphrothokholi yokuxhumana yedijithali efana ne-HART.

Isinxephezelo Sokushisa: Amasekhethi esinxephezelo alungisa isignali ngokusekelwe kuzinga lokushisa lokusebenza ukuze kuqinisekiswe ukunemba okungaguquki.

Ukuhanjiswa kwedatha

Isizukulwane Sokuphuma Kwesiginali: Isignali ecutshunguliwe iguqulelwa ekuphumeni kokugcina, kungaba kufomu le-analog (4-20 mA loop yamanje) noma ifomu ledijithali (kusetshenziswa izivumelwano ezifana ne-HART, FOUNDATION Fieldbus, noma i-Modbus).

Ukuxhumana Okukude: Amaphrothokholi edijithali anika amandla isidlulisi ukuthi sixhumane ngokuqondile namasistimu okulawula noma izikali eziphathwa ngesandla ukuze zicushwe, ziqashwe, futhi zihlolwe.

Zisebenza Kanjani Izinhlobo Ezihlukene Ze-Rosemount Pressure Transmitters?

I-Rosemount ikhiqiza izinhlobo ezahlukene zama-pressure transmitters, ngayinye yakhelwe izinhlelo zokusebenza ezithile kanye nezigaba zokucindezela. Nansi indlela uhlobo ngalunye olusebenza ngayo.

I-Differential Pressure Transmitter

Ukusebenza Isimiso: Ikala umehluko wengcindezi phakathi kwamaphoyinti amabili isebenzisa ukuxhumana okubili okuhlukene kwenqubo. Inzwa ithola umehluko wengcindezi futhi iyiguqule ibe isignali kagesi.

Izicelo: Okuvame ukusetshenziselwa ukulinganisa ukugeleza kwamapayipi, ukuqapha izinga lethangi, nokuhlola isimo sokuhlunga.

I-Absolute Pressure Transmitter

Ukusebenza Isimiso: Ikala ingcindezi ephelele yoketshezi noma igesi ngokuhlobene ne-vacuum ephelele (i-zero reference pressure). Inokuxhumana kwenqubo eyodwa, futhi inzwa ivalwe ngesivalu esiyisithenjwa.

Izicelo: Iwusizo ekuqaphelweni kwesistimu ye-vacuum kanye nezinhlelo zokusebenza lapho ukuhlukahluka komfutho womkhathi kungase kuthinte izilinganiso.

I-Gauge Pressure Transmitter

Ukusebenza Isimiso: Ikala ingcindezi ehlobene nomfutho womoya. Inzwa ithola umehluko phakathi kwengcindezi yenqubo kanye nengcindezi ye-ambient, isebenzisa uxhumano lwenqubo eyodwa.

Izicelo: Ilungele izinhlelo zokusebenza ezifana nokuqapha iphampu, lapho ukucindezela kubhekiselwa ku-ambient atmospheric pressure.

Isiphetho

I-Rosemount pressure transmitter iyithuluzi eliklanywe kakhulu elihlanganisa ubuchwepheshe bokuzwela obuthuthukisiwe nokucubungula amasignali ukuze kuhlinzekwe izilinganiso zengcindezi ezinembile nezithembekile ezindaweni ezifunwa kakhulu zezimboni. Ngokuqonda izingxenye kanye nezimiso zokulinganisa zezinhlobo ezihlukene zokudlulisa ukucindezela, ochwepheshe bangakhetha kangcono futhi bagcine idivayisi efanelekile yohlelo lwabo lokusebenza oluthile.
