Waya yeConstantan iwaya inoshandiswa zvakanyanya mukugadzira zvinhu zvemagetsi, zvemagetsi, uye zvemaindasitiri.

Mubvunzo unowanzo bvunzwa nezvazvo ndewekuti: Ndeipi imwe zita rewaya yeconstantan? Chinyorwa chino chichapindura mubvunzo uyu wepamoyo zvakadzama, uye chichatsanangurawo hunhu, mashandisirwo, uye zvigadzirwa zvedu zveconstantan wire zvemhando yepamusoro.

1. Mhinduro Yekutanga: Rimwe Zita reConstantan Wire

1.1 Zita rekuti "Primary Breath":Waya yeEureka

Zita rinonyanya kushandiswa rekuti constantan wire ndi "Eureka wire".

Zita iri rakabva kuEureka alloy, chinhu chekare chakagadzirwa neconstantan chakagadzirwa muzana remakore rechi19.

Nekufamba kwenguva, "Eureka wire" yave zita rinozivikanwa pasi rose re constantan wire munzvimbo dzakawanda nemaindasitiri.

1.2 Mamwe Mazita Edunhu/Etsika

Mune mimwe misika chaiyo, constantan wire ine mamwe mazita ekunyepedzera:

- Waya Yepamberi: Inoshandiswa mune mamwe maindasitiri ekuEurope, zvichireva waya dzeconstantan alloy dzine maumbirwo akafanana.

- Waya yeCuNi45: Yakatumidzwa zita nekuda kwemakemikari ayo (45% nickel, 55% copper), inowanikwa mumagwaro ehunyanzvi.

2. Sei Constantan Wire Iine Mazita Akawanda?

Kuvapo kwemazita akasiyana-siyana kunokonzerwa nezvinhu zviviri:

- Kwakatangira Nhoroondo: Matunhu akasiyana akagadzira ma alloys ane chekuita ne constantan akazvimiririra, zvichikonzera maitiro akasiyana ekutumidza mazita.

- Maitiro Ekushandisa: Muminda yakasarudzika (yakadai sekuyera kwakarurama), mazita evamwe anowanzo shandiswa kusiyanisa mamakisi chaiwo ewaya yeconstantan.

3. Hunhu Hukuru hweConstantan Wire (Eureka Wire)

3.1 Hunhu Hwakakosha hweKushanda

Pasinei nezita rakashandiswa, hunhu hwepakati hwewaya iyi ye alloy hunoenderana:

- Kudzivirira tembiricha yakaderera zvakanyanya: Inoita kuti tembiricha irambe yakasimba.

- Kudzivirira kwakanyanya: Yakakodzera kugadzira zvinodzivirira zvidiki, zvine hungwaru hwepamusoro.

- Kudzivirira ngura zvakanaka: Inogona kushandiswa munzvimbo dzakasiyana-siyana dzemaindasitiri.

3.2 Kuumbwa kweMakemikoro

Muumbirwo wewaya ye constantan (waya yeEureka) wakatarwa:

- Nickel (Ni): 45%

- Mhangura (Cu): 55%

Zvinhu zvinotevedzana (zvakaita semanganese) dzimwe nguva zvinowedzerwa kuti zviwedzere kushanda zvakanaka kwekugadzirisa.

4. Waya yeConstantan vs. Waya yeAlloy Yakafanana: Tafura Yekuenzanisa

Tafura inotevera inoenzanisa waya yeconstantan (Eureka wire) ne waya yemhangura-nickel 90/10 uye waya yemhangura yakachena, ichiratidza zvakanakira zvayo zvakasiyana:

Paramita Yekushanda	Waya yeConstantan (Waya yeEureka)	Waya yeCupro Nickel 90/10	Waya Yemhangura Yakachena
Kudzivirira Kupisa Kwemusanganiswa	Zvakaderera Zvikuru (±20 ppm/°C)	Zvakaderera (±100 ppm/°C)	Yakakwira (±4300 ppm/°C)
Kuramba kwemvura (20°C)	0.49 μΩ·m	0.17 μΩ·m	0.017 μΩ·m
Kupisa Kunoshanda Kwakanyanya	450°C	300°C	250°C
Kushandiswa Kwakajairika	Zvidziviriro Zvakakwana, Zviyero zveStrain	Waya dzemugungwa, Zvinochinja-chinja kupisa	Madhairekita Emagetsi Akajairika

5. Maitiro Akakosha Ekushandisa Constantan Wire (Eureka Wire)

5.1 Nzvimbo yeMagetsi neMagetsi

Kugadzirwa kwezvinodzivirira kupisa, potentiometers, uye zvinhu zvinodziya mumidziyo yemagetsi.

Waya yedu ye constantan inoita kuti zvikamu zvemagetsi zvishande zvakanaka munzvimbo dzakaoma dzekupisa.

5.2 Kuyerwa kweMaindasitiri

Kugadzirwa kwema "strain gauges", ma "thermocouples", uye mamwe ma "measurement sensors".

Kushanda kwayo pakupisa kwakaderera kunoita kuti ive yakanaka pakuunganidzwa kwedata kwakanyatsojeka.

5.3 Ndege neMotokari

Inoshandiswa muzvishandiso zvemagetsi zvekudzora mota uye muzvishandiso zvekuongorora mafambiro emhepo.

Inoenderana nekupisa kwakanyanya uye kudengenyeka kwemidziyo yekufambisa.

6. Zvigadzirwa zvedu zveConstantan Wire (Eureka Wire)

6.1 Magadzirirwo Akazara

Inovhara magiredhi e constantan akajairwa (CuNi45) uye dhayamita dzakasiyana dzewaya (0.05mm - 5.0mm).

Inotsigira waya isina chinhu uye waya inodzivirirwa nemhepo (PVC, Teflon insulation).

6.2 Mhinduro Dzakagadzirirwa

Inopa maumbirwo akagadzirwa nearuni anoenderana nezvinodiwa zvekudzivirira kupisa kana ngura.

Inopa waya dzakasungirirwa pamwe chete newaya dzakasungirirwa pamwe chete kuti chigadzirwa chigone kuchinjika.

6.3 Kudzora Hunhu Zvakasimba

Inoenderana neASTM B165 uye EN 1652 mitemo yepasi rose.

Kuyedzwa kwe100% usati wasvika, kusanganisira kukosha kwekudzivirira, dhayamita inoshivirira, uye kuongororwa kwekushisa.

7. Mhedziso

Zita rinonyanya kuzivikanwa re constantan wire ndiEureka wire, ine mamwe mazita edunhu akadai seAdvance Wire kana CuNi45 Wire.

Pasinei nezita rayo, mukana wayo mukuru wekudzivirira kugadzikana uye tembiricha yakaderera inoita kuti isatsiviwe munzvimbo dzakarurama.

Zvigadzirwa zvedu zvemhando yepamusoro zve constantan wire (Eureka wire) zvinoshandisa zvakanakira izvi zvizere. Kana uchida tambo ye alloy yakagadzirwa zvakanaka pabasa rako,ctaura nesukuti uwane mazano akagadzirirwa iwe pachako.
