LF-0020 sensor kutentha kwamadzi

LF-0020 sensa ya kutentha kwa madzi Yowonetsedwa Chithunzi

Kufotokozera Kwachidule:

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!

Malangizo ogwiritsira ntchito

Lumikizani sensa molingana ndi malangizo mu njira yolumikizira ma waya, ndiyeno ikani kafukufuku wa sensa m'nthaka kuti muyeze kutentha, ndikupereka mphamvu kwa osonkhanitsa ndi sensa kuti mupeze kutentha kwa madzi pamalo oyezera.

Kusamalitsa

1. Chonde yang'anani ngati zoyikazo sizili bwino ndikuwona ngati mtundu wa malondawo ukugwirizana ndi zomwe zasankhidwa.
2. Osalumikizana ndi magetsi, ndiyeno yatsani mukayang'ana mawaya.
3. Osasintha mosasamala zinthu kapena mawaya omwe adagulitsidwa pamene katunduyo achoka kufakitale.
4.Sensa ndi chipangizo cholondola.Chonde musamasule nokha kapena kukhudza pamwamba pa sensa ndi zinthu zakuthwa kapena zakumwa zowononga kuti mupewe kuwononga chinthucho.
5. Chonde sungani satifiketi yotsimikizira ndi satifiketi yogwirizana, ndipo mubwezereni ndi katunduyo pokonza.

Kusaka zolakwika

1.Zotsatira zikapezeka, chiwonetserochi chikuwonetsa kuti mtengo wake ndi 0 kapena wachoka.Onani ngati pali chotchinga kuchokera kuzinthu zakunja.Wosonkhanitsa sangathe kupeza zambiri molondola chifukwa cha vuto la waya.Chonde onani ngati mawayawo ndi olondola komanso olimba.
2.Ngati sizili zifukwa zomwe zili pamwambazi, chonde lemberani wopanga.
