Izidluliseli zoxinzelelo zizixhobo ezibalulekileyo ezisetyenziswa rhoqo ekulinganiseni, esweni kunye nokulawula ukwahluka koxinzelelo kwiigesi, ulwelo kunye nolwelo. Bangadlala indima ebalulekileyo ekuqinisekiseni ukhuseleko, ukusebenza kakuhle, kunye nokuthembeka kweenkqubo kumacandelo amaninzi oshishino. Ukuqonda ukuba yintoni umphumo we-pressure transmitter iyimfuneko kubachwephesha kunye nabaqhubi abaxhomekeke ekufundweni koxinzelelo oluchanekileyo kumsebenzi wabo.
Isidlulisi soxinzelelo ngokuqhelekileyo siguqula isignali efunyenwe kwinzwa yoxinzelelo edibeneyo ibe ngumqondiso omkhulu wombane othi emva koko udluliselwe kwinkqubo yokulawula (PLC/DCS) yokubeka iliso ngexesha lokwenyani kunye nolawulo. Ngokukodwa, iintlobo eziqhelekileyo zemveliso yomqondiso zimi ngolu hlobo lulandelayo:
Isiphumo sangoku:Olona hlobo luxhaphakileyo lwemveliso luphawu lwangoku, ngokuqhelekileyo kwimo ye-4-20 mA loop yangoku. Isiphumo sinobudlelwane bomgca kunye nexabiso loxinzelelo olunyuka ngokulinganayo kunye noxinzelelo lokufunda. Umzekelo, uluhlu lokulinganisa lwe-(0~10)bar lunokuthi luchaze inqaku elingu-zero njenge-4mA ngelixa uxinzelelo lwe-10bar luhambelana no-20mA okwenza igrafu yomgca ngaphezulu kwexesha. Olu luhlu luvumela ukutolika lula kwexabiso loxinzelelo kwaye lusetyenziswa ngokubanzi kwizicelo zoshishino ngenxa yokuqina kwayo ngokubhekiselele kwingxolo yombane.
Isiphumo seDijithali: Abathumeli boxinzelelo abakrelekrele banokubonelela ngemveliso yedijithali kwiindlela zonxibelelwano olulumkileyo njenge-HART, Modbus-RTU okanye ezinye iiprotocol. Iziphumo zedijithali zizisa iingenelo ezifana nokuchaneka okuphezulu, ukulungiswa kwendawo kunye nokuxilongwa, ulwazi olongezelelweyo olugqithiselwe kwi-PLS / DCS, kunye nokunciphisa ukungenwa kwingxolo. Ezi ziphumo zedijithali zithandwa kakhulu kwiinkqubo zangoku ezizenzekelayo.
IsiPhumo soMbane:Abanye abathumeli boxinzelelo banokubonelela ngemveliso yombane, ngokuqhelekileyo kwisithuba se-0-5V okanye i-0-10V. Uhlobo lwemveliso yombane aluqhelekanga kunelophu yangoku kodwa lunokuba luncedo ngakumbi kwizicelo apho iimpawu zombane zikhethwa kwiinkqubo zolawulo.
Ukuphuma rhoqo:Isiphumo sokuphindaphinda sibhekisa ekuguquleni ufundo loxinzelelo lube ngumqondiso wamaza. Nangona isignali yefrikhwensi ingasetyenziswanga kakhulu kwii-transmitters zoxinzelelo ngenxa yeendleko eziphezulu kunye nobunzima bobugcisa, kunokuba luncedo kwizicelo ezithile apho ukuhanjiswa kwedatha ngesantya esiphezulu kufuneka.
Emva kokukhetha umqondiso wesiphumo esifanelekileyo, ingqwalasela iya kuhlawulwa kwezinye izinto ezinokuchaphazela isiphumo ekusebenzeni:
Ulungelelwaniso:Ulungelelwaniso olufanelekileyo luyimfuneko yokufundwa koxinzelelo oluchanekileyo. Ulungelelwaniso lwefektri kufuneka lwenziwe ukuqinisekisa ukuba imveliso ihambelana nolona xinzelelo lokulinganisa ngendlela eyiyo ngokuthelekisa imveliso ye-transmitter kumgangatho owaziwayo woxinzelelo kunye nokulungelelanisa xa kuyimfuneko.
Iziphumo Zobushushu:Ubushushu bunokuba neempembelelo ekuchanekeni kwemveliso. Imbuyekezo yobushushu befektri inokunceda ukulungisa isiphumo sobushushu esingafunekiyo malunga ne-ambience, kodwa amaqondo obushushu agqithisileyo asenokuchaphazela ukusebenza kwesithuthi. Kubalulekile ukukhetha isidluliseli esilinganiswe kuluhlu oluthile lobushushu obusebenzayo.
Ukungcangcazela kunye nokothuka:Ukungcangcazela kunye nokuphazamiseka kuya kwenzeka kumacandelo athile phakathi kweemeko zoshishino ezinokukhokelela ekufundeni okungazinzanga kunye nomonakalo kwisixhobo. Kubalulekile ukukhetha ulwakhiwo oluqinileyo oluxhathisa ukungcangcazela kwaye usebenzise imilinganiselo eyimfuneko yokudambisa intshukumo ukukhusela isidima sesixhobo.
Iinkcazelo Ngeempawu eziPhakathi:Ubume bomlinganiselo wokulinganisa bunokuba nefuthe kwimveliso. Izinto ezifana ne-viscosity, ukubola, ukuhlukahluka ngokweemeko ze-matter kunye nobukho bamasuntswana axhonyiweyo kunokukhokelela ekufundweni koxinzelelo olutenxileyo. Ukukhetha uhlobo oluchanekileyo lokuhambisa oluhambelana neempawu ezithile zolwelo oluthile lokulinganisa lubalulekile ekusebenzeni kwesixhobo esifanelekileyo.
Iifom zemveliso yesignali ukusuka kwi-transmitter yoxinzelelo yinto ebalulekileyo yokusebenza kwayo. Njengomvelisi wesixhobo esinamava kwicandelo lolawulo lwenkqubo ngaphezulu kweminyaka engama-20,Shanghai Wangyuanibonelela ngezixhobo eziqinisekisiweyo nezithembekileyo zokulinganisa kunye nobutyebi bamava kuzo zonke iintlobo zeempawu zemveliso ukusuka kwi-4 ~ 20mA eqhelekileyo kunye nonxibelelwano oluhlakaniphile ukuya kwimveliso eyenziwe ngokwezifiso. Ukuba unawo nawuphi na umbuzo okanye imfuneko kwiziphumo zothumelo musa ukuthandabuza ukuqhagamshelana nathi.
