● Fa'atonuga o oloa
LF-0020 vai vevela sensor (transmitter) faʻaaogaina le thermistor maualuga maualuga e fai ma vaega faʻalogo, o loʻo i ai uiga o le saʻo maualuga ma le mautu lelei.O le transmitter faailoilo e faʻaaogaina le faʻaogaina o le eletise eletise, lea e mafai ona liua le vevela i le voltage tutusa poʻo le faʻailoga o loʻo iai nei e tusa ai ma manaʻoga eseese o tagata faʻaoga.O le meafaigaluega e laʻititi i le lapopoa, faigofie ona faʻapipiʻi ma feaveaʻi, ma e iai le faʻatinoga faʻalagolago;e faʻaaogaina laina faʻapitoa, laina lelei, malosi malosi o le uta, mamao mamao faʻasalalau, ma malosi malosi faʻalavelave faʻalavelave.E mafai ona faʻaaogaina lautele mo le fuaina o le vevela i fanua o le meteorology, siosiomaga, falesuesue, alamanuia ma faatoaga.

●Fua Fa'atatau
Ituaiga Volta (0～5V):
T=V / 5 × 70 -20
(T o le fuaina o le vevela (℃), V o le voluma gaosiga (V), o lenei fua faʻatatau i le fua faʻatatau -20 ~ 50 ℃)
T=V / 5 × 150 -50
(T o le fuaina o le vevela (℃), V o le voluma gaosiga (V), o lenei fua faʻatatau i le fua faʻatatau -50 ~ 100 ℃)
Ituaiga o iai nei(4~20mA)
T=(I-4)/ 16 × 70 -20
(T o le fuaina o le vevela (℃), o aʻu o le gaosiga o loʻo i ai nei (mA), o lenei ituaiga e fetaui ma le fua faʻatatau -20 ~ 50 ℃)
T=(I-4)/ 16 × 150 -50
(T o le fuaina o le vevela (℃), o aʻu o le gaosiga o loʻo i ai nei (mA), o lenei fua faʻatatau i le fua faʻatatau -50 ~ 100 ℃)
Fa'aaliga: E mana'omia le toe fa'atatauina o fua fa'atatau e fetaui ma fa'ailoga fa'ailoga eseese ma va'aiga eseese!
