Ama-pressure transmitters angamathuluzi abalulekile asetshenziswa kakhulu ukukala, ukuqapha kanye nokulawula ukuhluka kwengcindezi kumagesi, uketshezi noketshezi. Bangadlala indima ebalulekile ekuqinisekiseni ukuphepha, ukusebenza kahle, nokwethembeka kwezinqubo kuyo yonke imikhakha yezimboni eziningi. Ukuqonda ukuthi kuyini okuphumayo kwesidlulisi somfutho kuyadingeka kochwepheshe nabasebenzi abathembele ekufundweni kwengcindezi okunembile emsebenzini wabo.
Isidlulisi somfutho ngokuvamile siguqula isignali etholwe kunzwa yokucindezela ehlanganisiwe ibe isignali enkulu kagesi edluliselwa kusistimu yokulawula (PLC/DCS) yokuqapha nokulawulwa kwesikhathi sangempela. Ikakhulukazi, izinhlobo ezijwayelekile zokukhishwa kwesiginali zimi kanje:
Okukhiphayo kwamanje:Uhlobo olukhulu lokuphumayo oluvamile isignali yamanje, ngokuvamile esesimweni seluphu yamanje engu-4-20 mA. Okukhiphayo kunobudlelwano bomugqa nevelu yokucindezela ekhuphuka ngokulingana nokufundwa kwengcindezi. Isibonelo, ububanzi bokulinganisa bebha (0~10) bungase bubeke iphoyinti elinguziro njengo-4mA kuyilapho ukucindezela kuka-10bar kuhambisana no-20mA okwenza igrafu ewumugqa ngaphezu kwe-span. Lobu bubanzi buvumela ukutolika kalula kwevelu yengcindezi futhi busetshenziswa kabanzi ezinhlelweni zezimboni ngenxa yokuqina kwalo ngokumelene nomsindo kagesi.
Okukhiphayo Kwedijithali: Izidlulisi zengcindezi ezihlakaniphile zingahlinzeka ngokuphuma kwedijithali ngezindlela zokuxhumana ezihlakaniphile njenge-HART, Modbus-RTU noma ezinye izimiso. Okuphumayo kwedijithali kuletha izinzuzo ezifana nokunemba okuphezulu, ukuguqulwa kwendawo kanye nokuxilongwa, ulwazi olwengeziwe oludluliselwa ku-PLS/DCS, s kanye nokuncipha kokungenwa nomsindo. Le miphumela ehlakaniphile yedijithali iya ngokuya iduma ezinhlelweni zesimanje ezishintshayo.
I-Voltage Output:Amanye ama-pressure transmitters angahlinzeka ngokuphuma kwamandla kagesi, ngokuvamile esikhathini esingu-0-5V noma esingu-0-10V. Uhlobo lokukhipha amandla kagesi luvamile kancane kuneluphu yamanje kodwa lungaba usizo ikakhulukazi ezinhlelweni lapho amasignali kagesi ekhethwa kumasistimu okulawula.
Imvamisa okukhiphayo:I-frequency output isho ukuguqula ukufundwa kwengcindezi kube isignali yefrikhwensi. Nakuba isignali yefrikhwensi ingavamile ukusetshenziswa kuma-transmitter okucindezelayo ngenxa yezindleko eziphezulu nobunkimbinkimbi bobuchwepheshe, Ingase ibe nenzuzo ezinhlelweni ezithile lapho kudingeka khona ukudluliswa kwedatha ngesivinini esikhulu.
Ngemva kokukhetha isignali efanelekile yokuphumayo, ukunakwa kuzophinde kukhokhwe kwezinye izici ezingase zibe nomthelela ekuphumeni ekusebenzeni:
Ukulinganisa:Ukulinganisa okufanele kuyisidingo sokufundwa kwengcindezi okunembile. Ukulinganisa kwasefekthri kufanele kwenziwe ukuze kuqinisekiswe ukuthi okukhiphayo kuhambisana nokucindezela kwangempela kokulinganisa ngendlela efanele ngokuqhathanisa okuphumayo kwesidluliseli nezinga lengcindezi elaziwayo bese kulungiswa lapho kudingekile.
Imiphumela Yezinga Lokushisa:Izinga lokushisa lingaba nomthelela ekunembeni kokuphumayo. Isinxephezelo sezinga lokushisa lasefekthri singasiza ukulungisa umphumela wezinga lokushisa ongafuneki endaweni ezungezile, kodwa amazinga okushisa adlulele asengaphazamisa ukusebenza kwesidlulisi. Kubalulekile ukukhetha isidluliseli esilinganiselwe ngebanga elithile lokushisa lokusebenza.
Ukudlidliza kanye Nokwethuka:Ukudlidliza nokushaqeka kuzokwenzeka kwezinye izigaba phakathi kwezindawo zezimboni ezingaholela ekufundeni okungazinzile kanye nokulimala kwethuluzi. Kubalulekile ukukhetha idizayini eqinile engazweli nokudlidliza futhi usebenzise izinyathelo ezidingekayo zokudambisa ukudlidliza ukuze uvikele ubuqotho bensimbi.
Izici Ezimaphakathi:Imvelo yendlela yokulinganisa ingase ibe nomthelela ekuphumeni. Izinto ezifana ne-viscosity, ukugqwala, ukuhlukahluka kwezimo zendaba kanye nokuba khona kwezinhlayiya ezimisiwe kungase kuholele ekufundweni kwengcindezi echezukile. Ukukhetha uhlobo olulungile lwesidluliseli oluhambisana nezakhiwo ezithile zoketshezi oluthile lokulinganisa kubalulekile ekusebenzeni kahle kwensimbi.
Amafomu okukhipha isignali asuka kusidlulisi sokucindezela ayingxenye ebalulekile yokusebenza kwawo. Njengomkhiqizi wezinsimbi onolwazi emkhakheni wokulawula inqubo iminyaka engaphezu kwengu-20,Shanghai Wangyuaninikeza amathuluzi okulinganisa afakazelwe futhi anokwethenjelwa anolwazi oluningi kuzo zonke izinhlobo zamasiginali okukhiphayo kusukela ku-4~20mA evamile kanye nokuxhumana okuhlakaniphile kuye kokukhishwayo okwenziwe ngendlela oyifisayo. Uma unombuzo noma imfuneko kokuphumayo kwe-transmitter ungangabazi ukusithinta.
