S5-200 S5-200 stainless steel 304 tank level sensor e nang le tlhahiso ea 4-20mA ke tharollo e tšoarellang haholo le e ts'epahalang e etselitsoeng likoloi tsa khoebo ka ho khetheha, lisebelisoa tsa jenereithara le lits'ebetso tse felletseng tsa taolo ea likoloi tsa likoloi. E etselitsoe ho fana ka tlhahlobo e tsoelang pele le e nepahetseng ea boemo ba mokelikeli, sensor ena e hokahana ka mokhoa o ts'oanang le meaho ea sejoale-joale ea telematics le taolo ea indasteri. Ka ho fana ka lintlha tse nepahetseng tsa mafura, e thusa basebetsi ba likepe ho ntlafatsa tšebeliso ea mafura, ho lemoha mefokolo, le ho ntlafatsa katleho ea ts'ebetso libakeng tse fapaneng tsa thomello.
Kaho ea tšepe e sa tsitsang ea 304 e matsutla
E entsoe ka tšepe ea boleng bo holimo ea 304, sensor ena e fana ka khanyetso e ntle ea kutu le ho tšoarella ka mokhoa o ikhethang oa mochini. Lisebelisoa tsa indasteri le lisebelisoa tsa mehala hangata li sebetsa maemong a thata moo litanka tsa mafura li lulang li pepesehetse maemo a leholimo a feteletseng, ho thothomela ho matla, le litšila tse matla tsa mokelikeli. Ntlo e matla ea tšepe e sa hloekang ea 304 e tiisa hore sensor e boloka botšepehi ba eona ba sebopeho le ho nepahala ha tekanyo ea nako e telele ea ts'ebetso, ho fokotsa haholo tlhokahalo ea tlhokomelo ea khafetsa le ho theola litšenyehelo tsohle tsa beng ba lihlopha tsa thepa.
PCB e hahiloeng ho The Head Unit & 4-20mA Output
Monyetla oa bohlokoa oa theknoloji oa sensor ea boemo bona ke PCB e hahelletsoeng hloohong. Ka ho aha lisebelisoa tsa elektroniki tse sebetsanang le matšoao ka kotloloho ka har'a yuniti ea hlooho e kopaneng, moralo o holisa bokhoni ba sebaka ha o ntse o sireletsa likarolo tse hlokolosi khatellong ea kantle ea tikoloho. Mokhoa ona o kopantsoeng o tiisa phetoho ea matšoao hang-hang mohloling. Ho feta moo, tlhahiso e tloaelehileng ea indasteri ea 4-20mA e fana ka phetisetso ea data ea analog e tsitsitseng haholo libakeng tse telele. Loop ea hajoale ea 4-20mA ka tlhaho e hanana le ho kena-kenana le motlakase (EMI) le ho theoha ha motlakase, e netefatsa hore li-Programmable Logic Controllers (PLCs) kapa li-dashboard tsa ho latela likepe li fumana lipalo tse sa sitisoeng, tsa boemo bo phahameng ba mafura.
Tšebeliso e Tloaelehileng le Maemo a Kopo
Ka lebaka la moralo oa eona o feto-fetohang le tlhahiso e tšepahalang ea lets'oao, sensor ea boemo bona e khona ho ikamahanya le maemo a fapaneng a lisebelisoa tsa indasteri, tsa khoebo le tsa mehala. Lisebelisoa tse tloaelehileng li kenyelletsa:
- Litanka tsa polokelo ea lik'hemik'hale, litsi tsa mafura le libaka tsa phetisetso ea lipeipi: Ho fana ka tlhahlobo ea bohlokoa ea thepa le ho thibela ho phalla ha thepa ea oli le khase.
- Lisebelisoa tsa ho hloekisa metsi, liliba tsa metsi, le liliba tse kolobileng tsa ho phahamisa metsi: Ho netefatsa taolo e nepahetseng ea boemo ba metsi le ts'ebetso e ts'eptjoang litsing tsa tsamaiso ea metsi ea 'masepala kapa indastering.
- Litanka tsa letsatsi la diesel bakeng sa li-gensets le li-rigs tsa offshore moo EMI e leng matla: Ho fana ka matšoao a tsitsitseng a analog esita le libakeng tse laoloang ke lerata le phahameng la motlakase le mechine e boima.
- Li-silos tsa lijo le lino tse nang le lisebelisoa tsa bohloeki tsa tri-clamp: Ho ts'ehetsa litlhoko tsa ts'ebetso ea bohloeki ha u ntse u boloka tekanyo e nepahetseng le e tsoelang pele ea molumo.
- Setsi sa mehala (baepolli, li-locomotives) se fepang PLC kapa SCADA DCS ka likarete tsa analoge tsa 4–20 mA: Ho kopanya ntle le matsapa litsamaisong tsa taolo ea lisebelisoa tse boima ho ntlafatsa tšebeliso ea mafura le ho ntlafatsa ho lateloa ha thepa ea mohala.
Hore na o ntse o ntlafatsa lits'ebeletso tsa polokelo ea liindasteri tse emeng kapa o kenya tšebetsong marang-rang a tsoetseng pele a taolo ea likoloi tsa makoloi, sensor ena ea 4-20mA e fana ka ts'epo, botsitso ba tikoloho, le botsitso ba matšoao ho ts'ehetsa liqeto tsa bohlokoa tsa ts'ebetso.
