RS485 4-20MA OUTPUT LORA LORAWAN Sensor e ka khonehang ea Metsi a Mobu
Likarolo tsa Sehlahisoa
● Sesebediswa sa calibration sa othomathike se sebelisetsoa ho lekanya sensor ka bonngoe, 'me ho nepahala ho ntlafala haholo.
● Ha ho ho hoholeha ho bakoang ke ho senyeha ha thepa ea ceramic.
● Feela pata sensor, beha oache le nako ea ho lekanya, o ka qala ho bokella data ntle le ho etsa lenaneo.
● Epoxy resin over overlapping ente ente process e tiisa hore e loketse bakeng sa lipatlisiso tsa nako e telele tsa ho lekola masimo.
● E ka fana ka li-server le software, e ka kopanya LORA LORAWAN WIFI 4G GPRS, e ka sheba data ka liselefouno le PCS.
Tšebeliso ea lihlahisoa
● Ntlha ea pele, etsa qeto ea botebo ba ho kenya le boemo ba matla a metsi a mobu;
● Nka sampuli ea mobu sebakeng sa ho kenya, eketsa metsi le seretse ho sampuli ea mobu, 'me u tlatse seretse se khonang ho ntša metsi ka seretse;
● Sensor e koahetsoeng ka seretse e patoa sebakeng sa ho kenya, 'me mobu o ka khutlisetsoa morao.
Lisebelisoa tsa Sehlahisoa
Sehlahisoa sena se ka sebelisoa haholo ho nosetsa, ho ntša metsi, ho fana ka motheo oa saense bakeng sa kholo ea lijalo le libaka tse omeletseng, mobu o leqhoa, litsela le masimo a mang a lipatlisiso tsa metsi a mobu.

P: Ke litšobotsi life tse ka sehloohong tsa sensor ee ea mongobo oa mobu?
A: Ke lisebelisoa tsa ceramic mme li lekanya mefuta e mengata ea metsi a mobu ntle le tlhokomelo le ho lekanya, tiiso e ntle ka IP68 e sa keneleng metsi, e ka patoa ka botlalo mobung bakeng sa tlhahlobo e tsoelang pele ea 7/24.
P: Nka fumana disampole?
A: E, re na le thepa setokong ho u thusa ho fumana lisampole kapele kamoo re ka khonang.
P: Phepelo e tloaelehileng ea motlakase le tlhahiso ea lets'oao ke eng?
A: 5 ~ 24V DC (ha lets'oao la tlhahiso ke RS485)
12 ~ 24VDC (ha lets'oao la tlhahiso ke 4 ~ 20mA)
P: Nka bokella lintlha joang?
A: U ka sebelisa mochine oa hau oa data kapa mochine oa phetisetso ea waelese haeba u na le , re fana ka protocol ea puisano ea RS485-Mudbus. Re ka boela ra fana ka module ea phetisetso ea waelese ea LORA/LORANWAN/GPRS/4G e tsamaellanang ha o e hloka.
P: Bolelele bo tloaelehileng ba thapo ke bofe?
A: Bolelele ba eona bo tloaelehileng ke 2m.Empa e ka etsoa ka mokhoa o ikhethileng, MAX e ka ba limithara tse 1200.
P: Sensor ee e phela nako e kae?
A: Bonyane lilemo tse 3 kapa ho feta.
P: Nka tseba tiisetso ea hau?
A: E, hangata ke selemo se le 1.
P: Nako ea ho fihla ke mang?
A: Hangata, thepa e tla tlisoa matsatsing a 1-3 a ho sebetsa ka mor'a ho fumana tefo ea hau.Empa ho itšetlehile ka bongata ba hau.
