Umphumela olinganiswe umdlulisi wengcindezi ohlukile umehluko wengcindezi, okungukuthi, P = F / S. Lapho izinga lokushisa lishintsha, yize umthamo womkhiqizo kawoyela unweba noma uncipha, futhi izinga langempela loketshezi liyakhula noma liyancipha, ingcindezi etholwayo ihlala ifana. Uma umsebenzisi edinga ukubonisa izinga langempela likaketshezi, lingaxazululwa futhi ngokwethula isinxephezelo samazinga okushisa esiphakathi.
Ukukhipha izintambo ezimbili kuyindlela yokukhipha okuthuthukile ethekwini lamanje le-analog serial, enezinzuzo ezinkulu eziyisithupha:
1. Isidlulisi sokucindezela okuhlukile asithinteka kalula yi-thermocouples ye-parasitic kanye nokwehla kwamandla okumelana nokushisa i-e drift eceleni kocingo, ikakhulukazi ngaloIsidlulisi sokucindezela umehluko. Izintambo ezishibhile nezincane ezisontekile zingasetshenziswa.
2. Lapho ukumelana nokukhishwa komthombo wamanjeIsidlulisi sokucindezela okuhlukileInkulu ngokwanele, amandla kagesi angeniswe kwi-wire loop ngokuhlanganisa insimu kazibuthe ngeke abe nomthelela omkhulu. Ngoba amanje okubangelwa umthombo wokuphazamiseka incane kakhulu, ukusetshenziswa kwezintambo ezisontekile ngokuvamile kunganciphisa ukuphazamiseka.
3. Ukuphazanyiswa kokuphazamiseka kokudlulisa ingcindezi yohlukile kuzodala iphutha elihlobene nokumelana kwesamukeli. Nge-4-20 mA loop yezintambo ezimbili, ukumelana nokwamukela kokudlulisa kwengcindezi yokuhlukanisa imvamisa kungu-250 Ω (ukusakaza i-Uout = 1 ~ 5 V). Lokhu kumelana kuncane kakhulu ukuthi kungakhiqiza iphutha elibalulekile, ngakho-ke ubude bocingo obuvunyelwe bude futhi kude kunabo bohlelo lwe-telemetry lwe-voltage.
4. Idivayisi ngayinye yokubonisa noma yokurekhoda yomgcini wokudlulisa umfanekiso wengcindezi ingashintshwa phakathi kweziteshi ezahlukahlukene ezinobude obungalingani kocingo, futhi ngeke kube khona umehluko ekunembeni ngenxa yobude obungalingani kocingo;
5. Umdlulisi wengcindezi encane usebenzisa i-4mA ngezinga zero, okwenza kube lula kakhulu ukwahlulela ukuthi umugqa wokudlulisa uvulekile noma inzwa iyalimala (0mA state).
6. Isidlulisi sokucindezela okuhlukile kulula ukufaka ukuvikela ukunyusa kanye namadivayisi okuvikela umbani ku-wire emibili itheku, okuzuzisa ukuphepha, ukuvikelwa kombani nokuvikelwa kokuqhuma.
I-LEFOO ithuthukisa futhi ikhiqize ukulawulwa kwengcindezi ejwayelekile ephezulu kanye nemishini yokulawula izinga lokushisa, futhi ihlinzeka ngezixazululo nezinto ezintsha. Onjiniyela bethu abaqinisekisiwe bangakha izixazululo ezifanele zokuqeda cishe zonke izinhlelo zokuphathwa kwamanzi. Kusukela ekuhlaziyweni kombiko wokuhlinzekwa kwamanzi, imidwebo eningiliziwe kanye neziphakamiso zesabelomali, ama-prototypes. Uma unezidingo, sicela ukhululekile ukubonisana nathi.
