Wayar ramuwa wasu wayoyi biyu ne masu rufin rufin da ke da ƙimar ƙima ɗaya da ƙarfin thermoelectromotive na madaidaicin ma'aunin zafi da sanyio (0 ~ 100°C).Kurakurai saboda canjin yanayin zafi a mahadar.Editan mai zuwa zai gabatar muku da wane nau'i ne na waya diyya na thermocouple, menene aikin na'urar ramuwa ta thermocouple, da rarrabuwa na waya diyya na thermocouple.
1. Wani abu ne waya diyya thermocouple?
Wayar ramuwa ta gabaɗaya tana buƙatar ingantattun na'urorin lantarki da mara kyau su kasance iri ɗaya da abubuwa masu kyau da marasa kyau na thermocouple.K-nau'in thermocouples sune nickel-cadmium (tabbatacce) da nickel-silicon (mara kyau), don haka bisa ga ma'auni, ya kamata a zaɓi wayoyi na ramuwa na nickel-cadmium-nickel-silicon.
2. Menene aikin waya diyya na thermocouple
Shi ne don tsawaita wutar lantarki mai zafi, wato, ƙarshen sanyi na thermocouple ta hannu, kuma a haɗa tare da kayan nuni don samar da tsarin auna zafin jiki.Hakanan ana ɗaukar ma'aunin ƙasa na IEC 584-3 "Thermocouple Sashe na 3 - Waya Ramuwa".Ana amfani da samfuran ne a cikin na'urori masu auna zafin jiki daban-daban, kuma an yi amfani da su sosai a cikin makamashin nukiliya, man fetur, sinadarai, karafa, wutar lantarki da sauran sassan.
3. Rarraba wayoyi diyya na thermocouple
A ka'ida, an raba shi zuwa nau'in tsawo da nau'in ramuwa.Nau'in sinadari na gwargwado na nau'in tsawaitawa iri ɗaya ne da na ma'aunin thermocouple, don haka ƙarfin wutar lantarki shima iri ɗaya ne.An wakilta shi da "X" a cikin samfurin, kuma nau'in sinadarai na yau da kullun na waya mai nau'in ramuwa iri ɗaya ne.Ya bambanta da ma'aunin ma'aunin ma'aunin zafi da sanyio, amma a cikin kewayon zafin aikin sa, ƙarfin wutar lantarki yana kusa da ƙimar ƙima na ma'aunin ma'aunin ma'aunin zafi da sanyio, wanda “C” ke wakilta a cikin ƙirar.
daidaiton ramuwa ya kasu kashi-kashi na yau da kullun da madaidaicin sa.Kuskuren bayan biyan ma'auni daidai yake yawanci rabin abin da ake buƙata na yau da kullun, wanda galibi ana amfani dashi a wuraren da ake buƙatar daidaiton ma'auni.Misali, don wayoyi na ramuwa na lambobin kammala karatun S da R, haƙurin madaidaicin sa shine ± 2.5°C, kuma haƙurin ƙimar talakawa shine ± 5.0°C;don wayoyi ramuwa na lambobin kammala karatun K da N, haƙurin madaidaicin sa shine ± 1.5°C, haƙurin ƙimar talakawa shine ± 2.5℃.A cikin samfurin, ba a yi alama na talakawa ba, kuma an ƙara ma'auni daidai da "S".
Daga yanayin zafin aiki, an raba shi zuwa amfani na gaba ɗaya da amfani mai jure zafi.Matsakaicin zafin aiki na amfanin gabaɗaya shine 0 ~ 100 °C (kaɗan sune 0 ~ 70 °C);
Bugu da kari, ana iya raba core na waya zuwa wayoyi diyya guda daya da kuma Multi-core ( soft wire), kuma za a iya raba su zuwa na yau da kullun da kuma na garkuwar ramuwa gwargwadon ko suna da abin kariya, sannan akwai kuma wayoyi na diyya don da'irori masu aminci da aka keɓe don abubuwan da ba su iya fashewa.
