● Umyalelo Womkhiqizo
Inzwa yezinga lokushisa lamanzi ye-LF-0020 (i-transmitter) isebenzisa i-thermistor enembayo ephezulu njengengxenye yenzwa, enezici zokunemba kokulinganisa okuphezulu nokuzinza okuhle.I-transmitter yesiginali yamukela imodyuli edidiyelwe yesekethe ethuthukisiwe, engaguqula izinga lokushisa libe yi-voltage ehambisanayo noma isignali yamanje ngokuya ngezidingo ezahlukahlukene zabasebenzisi.Ithuluzi lincane ngosayizi, kulula ukulifaka futhi liyaphatheka, futhi linokusebenza okuthembekile;yamukela imigqa yokuphathelene, umugqa omuhle, umthamo oqinile wokulayisha, ibanga elide lokudlulisela, kanye nekhono eliqinile lokulwa nokuphazamiseka.Ingasetshenziswa kabanzi ukulinganisa izinga lokushisa emkhakheni we-meteorology, imvelo, ilabhorethri, imboni kanye nezolimo.

●Ifomula yokubala
Uhlobo lwe-voltage(0～5V):
T=V / 5 × 70 -20
(T inani lokushisa elilinganisiwe (℃), V i-voltage ephumayo (V), le fomula ihambisana nebanga lokulinganisa -20 ~ 50 ℃)
T=V / 5 × 150 -50
(T inani lokushisa elilinganisiwe (℃), V i-voltage ephumayo (V), le fomula ihambisana nebanga lokulinganisa -50 ~ 100 ℃)
Uhlobo lwamanje (4～20mA)
T=(I-4)/ 16 × 70 -20
(T izinga lokushisa lokulinganisa (℃), mina ngingumphumela wamanje (mA), lolu hlobo luhambisana nebanga lokulinganisa -20 ~ 50 ℃)
T=(I-4)/ 16 × 150 -50
(T yinani lokushisa elilinganisiwe (℃), mina ngingumphumela wamanje (mA), le fomula ihambisana nebanga lokulinganisa -50 ~ 100 ℃)
Qaphela: Amafomula wokubala ahambisana nemiphumela ehlukene yesiginali kanye nobubanzi obuhlukile bokulinganisa kudingeka abalwe kabusha!
