Lintho Tse Lumellanang
Khetha Letšoao le nepahetseng la Output
Sephetho sa transmitter se tlameha ho hokahana le sistimi ea hau ea taolo kapa ea ho beha leihlo:
- 4-20 mA: Tekanyetso ea lits'ebetso tsa indasteri, e tšepahalang bakeng sa phetiso ea mats'oao a malelele.
- 0-10 V: E loketse lits'ebetso tse thehiloeng ho li-voltage, tse sebelisoang hangata ho tlhophiso ea likoloi kapa tse nyane.
- Liphetho tsa Dijithale (mohlala, HART, Modbus): E ratoa bakeng sa litsamaiso tse bohlale tse hlokang tlhahlobo kapa tlhophiso e hole.
Netefatsa hore lets'oao la tlhahiso le tsamaisana le litlhoko tsa sistimi ea hau ho netefatsa khokahanyo e se nang moeli.
Hlahloba Litlhoko tsa Tikoloho le Polokeho
Li-transmitters tsa inline hangata li pepesetsoa maemo a phephetsang:
- Libaka tse Kotsi: Ts'ebelisong ea oli le khase (mohlala, liphaephe, libaka tsa ho hloekisoa), khetha li-transmitters tse thibelang ho phatloha kapa tse sireletsehileng ka tlhaho tse netefalitsoeng ho latela maemo a kang ATEX, FM, kapa CSA ho thibela likotsi tsa ho tima.
- Tšireletso ea Ingress (Litekanyetso tsa IP/NEMA): Bakeng sa tikoloho ea kantle kapa e mongobo, khetha transmitter e nang le boemo bo holimo ba IP (mohlala, IP67 kapa IP68) ho itšireletsa khahlanong le lerōle, metsi kapa oli e kenang.
- Mocheso Range: Netefatsa hore transmitter e sebetsa ka har'a meeli ea mocheso oa sistimi ea hau. Li-transmitter tsa inline lits'ebetsong tsa mocheso o phahameng (mohlala, tlhahlobo ea oli ea enjine) li hloka mamello e matla ea mocheso.
Khetha Khokahano e nepahetseng ea Ts'ebetso
Li-transmitter tsa inline li tlameha ho hokela ka mokhoa o sireletsehileng pompong:
- Khokahano e Mehala: Likhetho tse tloaelehileng joalo ka 1/4” NPT, G1/2, kapa likhoele tsa M20 li loketse lits'ebetso tse ngata tsa inline Etsa bonnete ba ho tiisa ka nepo (mohlala, O-rings kapa PTFE tape) ho thibela ho lutla.
- Flanged Connections: E sebelisoa ka liphaephe tse nang le khatello e phahameng kapa tse bophara bo boholo bakeng sa marotholi a tlaase a khatello le ho kenya ka mokhoa o sireletsehileng.
- Ho lumellana ha Pipe Size: Netefatsa hore khokahano ea transmitter e tsamaisana le bophara ba phaephe ea hau ho qoba lithibelo tsa phallo kapa mathata a ho kenya.
