● Malangizo a Zamalonda
LF-0020 sensa ya kutentha kwa madzi (transmitter) imagwiritsa ntchito thermistor yolondola kwambiri ngati chigawo chomverera, chomwe chimakhala ndi miyeso yolondola kwambiri komanso kukhazikika kwabwino.Ma transmitter amatengera gawo lapamwamba lophatikizika, lomwe lingasinthe kutentha kukhala voteji yofananira kapena chizindikiro chapano malinga ndi zosowa zosiyanasiyana za ogwiritsa ntchito.Chidacho ndi chaching'ono, chosavuta kukhazikitsa ndi kunyamula, ndipo chimakhala ndi ntchito yodalirika;imatenga mizere ya eni ake, mzere wabwino, mphamvu yonyamula katundu, mtunda wautali wotumizira, ndi mphamvu zotsutsana ndi kusokoneza.Itha kugwiritsidwa ntchito kwambiri pakuyeza kutentha m'magawo a meteorology, chilengedwe, labotale, mafakitale ndi ulimi.

●Kuwerengera Formula
Mtundu wamagetsi (0 ~ 5V):
T=V / 5 × 70 -20
(T ndi kuyeza kutentha mtengo (℃), V ndi linanena bungwe voteji (V), chilinganizo ichi chikufanana muyeso osiyanasiyana -20 ~ 50 ℃)
T=V / 5 × 150 -50
(T ndiye mtengo woyezera kutentha (℃), V ndi mphamvu yotulutsa (V), chilinganizochi chikufanana ndi muyeso wosiyanasiyana -50 ~ 100 ℃)
Mtundu wapano (4～20mA)
T=(I-4)/ 16 × 70 -20
(T ndi muyeso kutentha mtengo (℃), Ine linanena bungwe panopa (mA), mtundu uwu limafanana muyeso osiyanasiyana -20 ~ 50 ℃)
T=(I-4)/ 16 × 150 -50
(T ndiye mtengo woyezera kutentha (℃), ine nditulutsa pano (mA), fomula iyi imagwirizana ndi muyeso woyezera -50 ~ 100 ℃)
Zindikirani: Ma formula owerengera omwe amafanana ndi ma siginoloji osiyanasiyana komanso miyeso yosiyanasiyana yoyezera ayenera kuwerengedwanso!
