Terata ea Constantan ke terata ea motsoako o hanyetsanang le ho nepahala e sebelisoang haholo, e ratoang masimong a tekanyo ea motlakase, ea elektroniki le ea indasteri.

Potso e tloaelehileng ka eona ke ena: Lebitso le leng la terata ea constantan ke lefe? Sengoloa sena se tla araba potso ena ea mantlha ka botlalo, 'me se tla boela se hlahise litšobotsi, lits'ebetso le lihlahisoa tsa rona tsa terata ea constantan tsa boleng bo holimo.

1. Karabo ea Bohlokoa: Lebitso le Leng la Constantan Wire

1.1 Lebitso la pele la lebitso la boswaswi:Terata ea Eureka

Lebitso le tloaelehileng haholo la terata ea constantan ke "terata ea Eureka".

Lebitso lena le simolohile ho motsoako oa Eureka, e leng thepa ea khale e thehiloeng ho constantan e qapiloeng lekholong la bo19 la lilemo.

Ha nako e ntse e ea, "terata ea Eureka" e fetohile lebitso le tloaelehileng la terata ea constantan libakeng tse ngata le liindastering.

1.2 Mabitso a mang a Sebaka/a Tloaelo

Limmarakeng tse ling tse itseng, terata ea constantan e boetse e na le mabitso a mang a mabitso a sa tsejoeng:

- Terata e Tsoetseng Pele: E sebediswa masimong a itseng a diindasteri a Yuropa, ho bolelwa dithapo tsa alloy tsa constantan tse nang le metswako e tshwanang.

- Terata ea CuNi45: E reheletsoe ka sebopeho sa eona sa lik'hemik'hale (45% nickel, 55% koporo), e tloaelehileng litokomaneng tsa tekheniki.

2. Ke Hobane'ng ha Constantan Wire e na le Mabitso a Mangata?

Boteng ba mabitso a mabitso a mangata a mabitso a mabitso bo bakoa haholo-holo ke mabaka a mabeli:

- Tšimoloho ea Histori: Libaka tse fapaneng li hlahisitse li-alloy tse amanang le constantan ka boikemelo, e leng se ileng sa lebisa ho mekhoa e fapaneng ea ho reha mabitso.

- Maemo a Tshebediso: Mafapheng a ikgethang (jwalo ka tekanyo ya ho nepahala), mabitso a mang a atisa ho sebediswa ho kgetholla dikereiti tse itseng tsa terata ya constantan.

3. Litšobotsi tsa Bohlokoa tsa Terata ea Constantan (Terata ea Eureka)

3.1 Litšobotsi tsa Tshebetso ea Bohlokoa

Ho sa tsotelehe lebitso le sebelisitsoeng, litšobotsi tsa mantlha tsa terata ena ea motsoako lia tšoana:

- Koefficient e tlase haholo ea khanyetso ea mocheso: E netefatsa boleng bo tsitsitseng ba khanyetso ho feto-fetohang ha mocheso.

- Ho hanyetsa ho hoholo: E loketse ho etsa li-resistor tse nyane, tse nepahetseng haholo.

- Ho hanyetsa mafome hantle: E ikamahanya le maemo a fapaneng a indasteri a bonolo.

3.2 Sebopeho sa Lik'hemik'hale

Sebopeho se tloaelehileng sa terata ea constantan (terata ea Eureka) se tsitsitse:

- Nikele (Ni): 45%

- Koporo (Cu): 55%

Dielemente tse latelang (tse kang manganese) ka nako e 'ngoe lia eketsoa ho ntlafatsa ts'ebetso ea ts'ebetso.

4. Terata ea Constantan khahlanong le Terata e Tšoanang ea Motsoako: Tafole ea Papiso

Tafole e latelang e bapisa terata ea constantan (terata ea Eureka) le terata ea koporo-nickel 90/10 le terata ea koporo e hloekileng, e totobatsa melemo ea eona e ikhethang:

Paramethara ea Tshebetso	Terata ea Constantan (Terata ea Eureka)	Terata ea Cupro Nickel 90/10	Terata e Hloekileng ea Koporo
Mokhahlelo oa Khanyetso oa Thempereichara	Tlase Haholo (±20 ppm/°C)	Tlase (±100 ppm/°C)	Holimo (±4300 ppm/°C)
Ho hanyetsa (20°C)	0.49 μΩ·m	0.17 μΩ·m	0.017 μΩ·m
Mocheso o phahameng ka ho fetisisa oa ho sebetsa	450°C	300°C	250°C
Tšebeliso e Tloaelehileng	Li-resistor tse nepahetseng, Litekanyo tsa khatello	Lithapo tsa Metsing, Bafani ba Mocheso	Bakhanni ba Motlakase ba Kakaretso

5. Liketsahalo tsa Bohlokoa tsa Tšebeliso ea Mohala oa Constantan (Mohala oa Eureka)

5.1 Tšimo ea Elektroniki le Motlakase

Tlhahiso ea li-resistor tse nepahetseng, li-potentiometer, le likarolo tsa ho futhumatsa lisebelisoa tsa elektroniki.

Terata ea rona ea constantan e netefatsa ts'ebetso e tsitsitseng ea likarolo tsa elektroniki maemong a rarahaneng a mocheso.

5.2 Tekanyo ea indasteri

Tlhahiso ea li-strain gauge, li-thermocouple, le li-sensor tse ling tsa tekanyo.

Coefficient ea eona ea mocheso o tlase e etsa hore e be ntle bakeng sa pokello ea data e nepahetseng haholo.

5.3 Lifofane le Likoloi

E sebelisoa litsamaisong tsa taolo ea elektroniki tsa likoloi le lisebelisoa tsa ho nepahala ha sefofane.

E ikamahanya le mocheso o matla le tikoloho e thothomelang ea lisebelisoa tsa lipalangoang.

6. Lihlahisoa tsa rona tsa Constantan Wire (Eureka Wire)

6.1 Litlhaloso tse Felletseng

E akaretsa maemo a tloaelehileng a constantan (CuNi45) le bophara bo fapaneng ba terata (0.05mm - 5.0mm).

E tšehetsa dikgetho tsa terata e se nang letho le terata e sirelelitsoeng (PVC, Teflon insulation).

6.2 Litharollo tse Ikhethileng

E fana ka metsoako ea alloy e ikhethileng bakeng sa litlhoko tse khethehileng tsa mocheso kapa ho hanyetsa mafome.

E fana ka ts'ebetso ea terata e lahlehileng le terata e kopaneng ho ntlafatsa ho tenyetseha ha sehlahisoa.

6.3 Taolo e Tiileng ea Boleng

E latela maemo a machaba a ASTM B165 le EN 1652.

Teko ea pele ho pepa ea 100%, ho kenyeletsoa boleng ba khanyetso, mamello ea bophara, le liteko tsa coefficient ea mocheso.

7. Qetello

Lebitso le leng le tloaelehileng haholo bakeng sa terata ea constantan ke terata ea Eureka, e nang le mabitso a mang a libaka joalo ka Advance Wire kapa CuNi45 Wire.

Ho sa tsotelehe lebitso, molemo oa eona oa mantlha oa khanyetso e tsitsitseng le coefficient ea mocheso o tlase o etsa hore e se ke ea nkeloa sebaka masimong a nepahetseng.

Lihlahisoa tsa rona tsa boleng bo holimo tsa terata ea constantan (Eureka wire) li sebelisa melemo ena ka botlalo. Haeba u hloka terata e tšepahalang ea alloy bakeng sa projeke ea hau,cikopanye le ronabakeng sa likhothaletso tse ikhethileng.
