Mabaka a Bohlokoa a Hore na ke Hobaneng Terata e Tloaelehileng ea Motlakase e sa Sebetse

1. Ho lumellana ha thepa
- Li-thermocouple li entsoe ka lipara tse itseng tsa tšepe (mohlala.Mofuta oa Ke sebelisa Chromel le Alumel,Mofuta oa Je sebelisa Iron le Constantan).
- Ho sebelisa terata e tloaelehileng ea koporo ho ka sitisa potoloho ea thermoelectric, e leng se tla lebisa ho lipalo tse fosahetseng.
2. Khanyetso ea Mocheso
- Hangata li-thermocouple li sebetsa maemong a feteletseng a mocheso (ho tloha ho -200°C ho ea ho feta 2300°C, ho latela mofuta).
- Lithapo tse tloaelehileng li ka oxidation, tsa senyeha, kapa tsa qhibiliha tlas'a mocheso o phahameng, tsa baka ho sisinyeha kapa ho hloleha ha lets'oao.
3. Botšepehi ba Letšoao le Khanyetso ea Lerata
- Matšoao a thermocouple a hodimo ho di-millivolt, e leng se etsang hore a be kotsing ya ho kenngwa kgahlanong le motlakase (EMI).
- Terata e nepahetseng ea thermocouple e kenyelletsa tšireletso (mohlala, tšireletso e lohiloeng kapa ea foil) ho thibela lerata ho sotha lipalo.
4. Ho nepahala ha Tekanyo
- Mofuta o mong le o mong oa thermocouple (J, K, T, E, jj.) o na le mothapo o tloaelehileng oa motlakase le mocheso.
- Ho sebelisa terata e sa tsamaellaneng ho fetola kamano ena, e leng se lebisang liphosong tsa tlhahlobo le data e sa tšepahaleng.

Mefuta ea Thermocouple Terminal

Ho na le mefuta e 'meli e meholo ea terata ea thermocouple:
1. Terata ea Katoloso
- E entsoe ka metsoako e tšoanang le thermocouple ka boeona (mohlala, terata ea katoloso ea Type K e sebelisa Chromel le Alumel).
- E sebelisoa ho atolosa lets'oao la thermocouple libakeng tse telele ntle le ho hlahisa liphoso.
- Hangata e sebelisoa libakeng tse nang le mocheso o itekanetseng (kaha mocheso o phahameng o ntse o ka ama ho thibela mocheso).
2. Terata e Lefellang
- E entsoe ka thepa e fapaneng empa e tšoana le thermoelectric (hangata e theko e tlase ho feta metsoako e hloekileng ea thermocouple).
- E etselitsoe ho lekana le tlhahiso ea thermocouple mochesong o tlase (hangata e ka tlase ho 200°C).
- E sebediswa hangata diphanele tsa taolo le disebediswa moo mocheso o feteletseng e seng lebaka.
Mefuta ena ka bobeli e tlameha ho latela maemo a indasteri (ANSI/ASTM, IEC) ho netefatsa botsitso le ts'ebetso.

Ho Khetha Terata e Nepahetseng ea Thermocouple

Ha o kgetha terata ya thermocouple, nahana ka:
- Mofuta oa Thermocouple (K, J, T, E, jj.) – E tlameha ho tsamaisana le mofuta oa sensor.
- Tekanyo ea mocheso - Netefatsa hore terata e khona ho sebetsana le maemo a ts'ebetso a lebelletsoeng.
- Thepa ea ho Sireletsa – Fiberglass, PTFE, kapa sehatsetsi sa ceramic bakeng sa lits'ebetso tse chesang haholo.
- Litlhoko tsa ho Sireletsa – Sireletsa se lohiloeng kapa sa foil bakeng sa ts'ireletso ea EMI libakeng tsa indasteri.
- Ho tenyetseha le ho Tšoarella – Terata e qabeletsoeng bakeng sa ho kobeha ho tiileng, karolo e tiileng ea motheo bakeng sa ho kenya lintho ka mokhoa o tsitsitseng.

Litharollo tsa Rona tsa Thermocouple Wire tsa Boleng bo Holimo

Ho Tankii, re fana ka terata ea thermocouple ea boleng bo holimo e etselitsoeng ho nepahala, ho tšoarella le ho tšepahala. Lihlahisoa tsa rona li kenyelletsa:
- Mefuta e mengata ea Thermocouple (K, J, T, E, N, R, S, B) – E lumellana le litekanyetso tsohle tse kholo tsa thermocouple.
- Dikgetho tse Hanelang Mocheso o Phahameng le ho Sila – E loketse dibaka tse thata tsa diindasteri.
- Mefuta e Sirelelitsoeng le e Sirelelitsoeng – Fokotsa tšitiso ea matšoao bakeng sa lipalo tse nepahetseng.
- Bolelele le Litlhophiso tse Ikhethileng – E etselitsoe litlhoko tsa hau tse ikhethileng tsa kopo.

Li-thermocouple li tlameha ho hokahanngoa le terata e nepahetseng hore li sebetse hantle. Ho sebelisa terata e tloaelehileng ea motlakase ho ka lebisa liphosong tsa tekanyo, tahlehelo ea lets'oao, kapa esita le ho hloleha ha sensor. Ka ho khetha terata e nepahetseng ea thermocouple—ebang ke katoloso kapa e lefellang—u netefatsa ho nepahala ha nako e telele, botsitso le ts'ebetso litsamaisong tsa hau tsa ho lekola mocheso.

Bakeng sa tataiso ea litsebi le litharollo tsa terata ea thermocouple ea boleng bo holimo,iteanye le ronakajeno kapa sheba lethathamo la rona la lihlahisoa ho fumana se lumellanang hantle le sesebelisoa sa hau!
