Sensor ea Metsi a Mobu ea RS485 4-20MA LORA LORAWAN
Likarolo tsa Sehlahisoa
● Sesebelisoa sa ho lekanya ka boiketsetso se sebediswa ho lekanya sensor ka bonngoe, mme ho nepahala ho ntlafatswa haholo.
● Ha ho na ho thekesela ho bakoang ke ho senyeha ha thepa ea letsopa.
● Cheka sensor feela, beha nako ea oache le tekanyo, u ka qala ho bokella data ntle le ho e etsa mananeo.
● Ts'ebetso ea ho enta ente e kopaneng ea resin ea epoxy e netefatsa hore e loketse lipatlisiso tsa ho beha leihlo tšimo nako e telele.
● E ka fana ka li-server le software, e ka kopanya LORA LORAWAN WIFI 4G GPRS, e ka sheba data lifonong tsa thekeng le li-PCS.
Tšebeliso ea sehlahisoa
● Pele fumana botebo ba ho kenya le boemo ba matla a metsi a mobu;
● Nka sampole ea mobu sebakeng sa ho e kenya, eketsa metsi le seretse sampole ea mobu, 'me u tlatse sensor ea metsi a mobu ka seretse;
● Sensor e koahetsoeng ka seretse e patoa ho fihlela boemong ba ho kenngoa, 'me mobu o ka tlatsoa hape.
Lisebelisoa tsa Sehlahisoa
Sehlahisoa sena se ka sebelisoa haholo ho nosetseng, ho ntsha metsi, ho fana ka motheo oa saense bakeng sa kholo ea lijalo le libaka tse omileng, mobu o leqhoa, tsela le masimo a mang a lipatlisiso tsa metsi a mobu.

P: Litšobotsi tsa mantlha tsa sensor ena ea mongobo oa mobu ke life?
K: Ke thepa ea ceramic 'me e lekanya mefuta e mengata ea matla a metsi a mobu ntle le tlhokomelo le tlhahlobo, e ka koaloa hantle ka metsi a IP68, e ka patoa mobung ka botlalo bakeng sa tlhokomelo e tsoelang pele ea 7/24.
P: Na nka fumana disampole?
K: E, re na le thepa e teng setokong ho u thusa ho fumana disampole kapele kamoo re ka khonang.
P: Phepelo e tloaelehileng ea motlakase le tlhahiso ea lets'oao ke efe?
A: 5 ~ 24V DC (ha lets'oao la tlhahiso e le RS485)
12~24VDC (ha lets'oao la tlhahiso e le 4~20mA)
P: Nka bokella data joang?
K: O ka sebedisa mojule wa hao wa ho ngola data kapa wa phetiso ya waelese haeba o na le , re fana ka protocol ya puisano ya RS485-Mudbus. Re ka boela ra fana ka mojule wa phetiso ya waelese wa LORA/LORANWAN/GPRS/4G o tsamaellanang haeba o hloka.
P: Bolelele ba thapo e tloaelehileng ke bokae?
K: Bolelele ba yona bo tlwaelehileng ke 2m. Empa e ka fetolwa, MAX e ka ba dimithara tse 1200.
P: Sensor ena e phela nako e kae?
A: Bonyane dilemo tse 3 kapa ho feta.
P: Na nka tseba waranti ea hau?
K: E, hangata ke selemo se le seng.
P: Nako ea ho pepa ke efe?
K: Hangata, thepa e tla tlisoa matsatsing a 1-3 a mosebetsi kamora ho fumana tefo ea hau. Empa ho latela bongata ba hau.
