1. Ungayikhetha kanjani ukudluliselwa kwengcindezelo? Okokuqala, kuyadingeka ukuqinisekisa ukuthi hlobo luni lwengcindezi yokulinganisa
Okokuqala, nquma inani eliphakeme lengcindezi elinganisiwe ohlelweni. Ngokuvamile, kuyadingeka ukukhetha i-transmitter enebanga lokucindezela elicishe libe yizikhathi eziyi-1.5 kunenani eliphakeme. Lokhu kungenxa yokuba khona kweziqongo kanye nokushintshashintsha okungajwayelekile okuqhubekayo ezinhlelweni eziningi, ikakhulukazi ekulinganiseni kwengcindezi yamanzi nokucutshungulwa. Lezi ziqongo ezisheshayo zingalimaza izinzwa zengcindezi. Amanani aphezulu wokucindezela okuphezulu noma okudlula kancane inani elilinganisiwe le-transmitter kuzonciphisa isikhathi sokuphila kwenzwa, futhi ukwenza kanjalo kuzoholela ekunciphiseni ngokunemba. Ngakho-ke i-buffer ingasetshenziswa ukunciphisa ama-Pressure Burrs, kepha lokhu kuzonciphisa ijubane lokuphendula inzwa. Ngakho-ke lapho ukhetha ukudlulisela, kubalulekile ukubheka ngokugcwele ububanzi bokucindezela, ukunemba, nokuqina.
2. Hlobo luni lwengcindezelo ephakathi
Ngabe ama-viscous ketshezi kanye nodaka oluzolulwa i-interface lengcindezi, futhi azoxazulula noma izinto ezilonakalisayo zilimaza izinto zokuxhumana ngqo nale midiya. Lezi zinto ezingenhla zizonquma ukuthi zikhetha ulwelwesi lokuhlukaniswa okuqondile nezinto zokwakha ezifika ekuxhumaneni ngqo ne-medium.
I-3. Kudingeka ukunemba okungakanani ukudluliselwa kwengcindezi (ukubalwa kokunemba kwengcindezi)
Izici ezinquma ukunemba kufaka ukunganakwa, i-hysteresis, ukungaphindwanga, izinga lokushisa, izinga le-zero offset, kanye nethonya lokushisa. Kepha ikakhulukazi ngenxa yokungakhethi, i-hysteresis, ukungaphindwanga, kukhuphuka ukunemba, kuphakama inani.
4. Uhla lokushisa lwengcindezelo yokudlulisa
Imvamisa, i-Transmitter izolinganisa amazinga okushisa amabili, okukodwa kwalokho okushisa okujwayelekile okusebenzayo kanti okunye kungukushisa kwesinxephezelo sokushisa. Ibanga elijwayelekile lokushisa elisebenzayo libhekisela ebuhlu lokushisa be-transmitter lapho ingalimali ngesikhathi sokusebenza. Uma kudlula uhla lwesinxephezelo lokushisa, kungenzeka kungahlangabezani nezinkomba zokusebenza kohlelo lokusebenza lwayo.
Ibanga lokunxeshezelwa kwezimali zokushisa liyibanga elijwayelekile elincane kunebanga lokushisa elisebenzayo. Ukusebenza ngaphakathi kwaleli banga, i-Transmitter nakanjani izofinyelela izinkomba zayo ezilindelekile zokusebenza. Ushintsho lokushisa luthinta okuphumayo kusuka ezicini ezimbili: zero drift kanye nokuphuma okugcwele. Isibonelo, + / - x% / ℃ esikalini esigcwele, + / - x% / ℃ yokufunda, + / - x% yesilinganiso esigcwele lapho kufinyelela ibanga lokushisa eliphansi. Ngaphandle kwalezi zinhlaka, kungaholela ekungaqiniseki ukuthi kusetshenziswe. Ushintsho ekutholeni kokudlulisela okubangelwa izinguquko zengcindezi noma izinguquko zokushisa. Umphumela wokushisa uyingxenye eyinkimbinkimbi yokuqonda indlela yokusebenzisa i-transmitter.
5. Isiphi isibonakaliso sokuphuma esidlulayo sidinga ukuthola
Ukukhethwa kokukhishwa kwedijithali kwe-MV, v, Ma, kanye nemvamisa kuya ngezici ezahlukahlukene, kufaka phakathi ibanga phakathi kwe-Transmitter kanye nesilawuli se-amplifiers, nendawo yezikhulisi. Kumadivayisi amaningi we-OEM anamabanga amafushane phakathi kwama-transmitters kanye nabalawuli, usebenzisa ama-MA akhipha ama-transmitters kuyindlela yezomnotho nesebenzayo.
Uma kudingeka ukukhulisa isinali yokuphuma, kunconyelwa ukusebenzisa i-Transmitter nge-Amplification eyakhelwe ngaphakathi. Ngokudluliswa okude noma amasiginali wokuphazamiseka we-elekthronikhi aqinile, kungcono ukusebenzisa ukuphuma kwe-MA level noma umphumela wemvamisa.
Uma endaweni enezikhombisi eziphezulu ze-RFI noma i-EMI, ngaphezu kokukhetha i-MA noma imvamisa okukhishwayo, ukuvikelwa okukhethekile noma izihlungi kufanele nazo kufanele zibhekwe.
6. Yikuphi ukukhulisa i-voltage okufanele kukhethwe ama-transmitters wengcindezi
Uhlobo lwesiginali yokuphuma lunquma ukuthi iyiphi i-voltage yokuvuselela okufanele uyikhethe. Ama-transmitter amaningi anamadivayisi we-voltage acternal, ngakho-ke uhla lwabo lwe-Voltage Voltage lukhulu. Amanye ama-transmitters ahlelwa ngobuningi futhi adinga amandla aqinile okusebenza. Ngakho-ke, i-voltage yokusebenza inquma ukuthi isebenzisa inzwa enomlawuli. Lapho ukhetha i-Transmitter, kufanele kunikezwe ukucatshangelwa okuphelele kwezindleko zokusebenza kanye nezindleko zohlelo.
7. Ngabe sidinga ama-transmitters ngokuhlangana
Nquma ukuthi ukudluliselwa okudingekayo kungazivumelanisa nezimo eziningi izinhlelo zokusebenzisa. Ngokuvamile, lokhu kubalulekile, ikakhulukazi ngemikhiqizo ye-OEM. Lapho umkhiqizo uthunyelwa kwikhasimende, izindleko zokulinganisa ikhasimende liyabonakala. Uma umkhiqizo unokushintshana okuhle, ngisho nokushintsha ukudluliselwa okusetshenzisiwe ngeke kuthinte ukusebenza kohlelo lonke.
8. I-Transmitter idinga ukugcina ukuqina ngemuva kokuhlinzwa isikhathi
Iningi labadlulisela lizothola "ukushayela" ngemuva kokusebenza ngokweqile, ngakho-ke kuyadingeka ukuqonda ukuqina komhambisi ngaphambi kokuthenga. Lo msebenzi wangaphambilini unganciphisa izinkathazo ezahlukahlukene ezingase zivele ekusebenziseni okuzayo.
9. Ukupakishwa kwama-transmitters wengcindezi
Ukupakishwa kwe-transmitter kuvame ukunganakwa ngenxa ye-rack yayo, kepha lokhu kuzodalula kancane kancane izithiyo zayo ekusetshenzisweni okuzayo. Lapho ukhetha ukudlulisela, kubalulekile ukucabanga ngemvelo yokusebenza yesikhathi esizayo, umswakama, izindlela zokufaka, nokuthi kuzoba nemithelela eqinile noma ukunyakaza.
