NTC zinariya da azurfa guntu guntu aikin da aikace-aikace kwatanta

Menene bambance-bambancen aiki tsakanin kwakwalwan kwamfuta na thermistor NTC tare da na'urorin lantarki na zinariya da na'urorin lantarki, kuma ta yaya aikace-aikacen kasuwancin su ya bambanta?

NTC (Negative Temperature Coefficient) kwakwalwan zafin jiki tare da na'urorin lantarki na gwal da na'urorin lantarki na azurfa suna nuna bambance-bambance masu yawa a cikin aiki da aikace-aikacen kasuwa, da farko saboda abubuwan da ke cikin jiki da sinadarai na kayan lantarki. A ƙasa akwai cikakken bincike na kwatance:

I. Bambancin Aiki

1. Conductivity da Contact Resistance

• Gold Electrodes:
  • Kyakkyawan aiki mai kyau, ko da yake dan kadan ya fi azurfa (resistivity na zinariya: ~ 2.44 μΩ · cm vs. azurfa: ~ 1.59 μΩ · cm).
  • Ingantacciyar juriyar tuntuɓar juna saboda juriyar zinari ga iskar shaka, yana tabbatar da juriya kaɗan akan lokaci.
• Azurfa Electrodes:
  • Maɗaukakiyar ɗabi'a, amma mai saurin kamuwa da iskar shaka (musamman a cikin yanayin zafi mai zafi ko ɗanɗano), yana haifar da haɓaka juriya da rashin daidaituwar sigina.

2. Oxidation da Lalata Resistance

• Gold Electrodes:
  • Matsakaicin kwanciyar hankali na sinadarai; resistant zuwa hadawan abu da iskar shaka da lalata (misali, acid, alkalis), manufa domin matsananci yanayi (high zafi, lalata gas).
• Azurfa Electrodes:
  • Yana amsawa tare da sulfur da oxygen don samar da sulfide na azurfa / oxide, aikin ƙasƙanci akan lokaci lokacin da aka fallasa shi zuwa iska.

3. Tsantsar Zazzabi

• Gold Electrodes:
  • Kyakkyawan kwanciyar hankali mai zafi (mai tsayayya> 150 ° C), dacewa da aikace-aikacen masana'antu ko na kera (misali, sassan injin).
• Azurfa Electrodes:
  • Oxidation yana haɓaka a babban yanayin zafi; yawanci iyakance zuwa ≤100°C ba tare da fakitin kariya ba.

4. Solderability

• Gold Electrodes:
  • Mai jituwa tare da masu siyar da gama gari (misali, manna kwano), yana tabbatar da abin dogaro ga tsarin SMT mai sarrafa kansa.
• Azurfa Electrodes:
  • Yana buƙatar solder anti-oxidation ko mai kariyar nitrogen don hana lahani da ke haifar da iskar shaka (misali, haɗin gwiwar sanyi).

5. Rayuwa da Dogara

• Gold Electrodes:
  • Tsawon rayuwa, manufa don aikace-aikacen dogaro mai ƙarfi (misali, na'urorin likitanci, sararin samaniya).
• Azurfa Electrodes:
  • Gajeren rayuwa amma ya wadatar ga wurare masu laushi (misali, kayan aikin gida).

      

II. Bambance-bambancen Aikace-aikacen Kasuwa

1. Zinariya Electrode Chips

• Babban Ƙarshen Masana'antu & Kayan Wutar Lantarki na Mota:
  • Ƙungiyoyin sarrafa injin (ECU), tsarin sarrafa baturi (BMS), na'urori masu auna firikwensin masana'antu a cikin yanayin zafi mai zafi/vibration.
• Na'urorin Lafiya:
  • Kula da yanayin zafi a cikin hoton likita, masu sa ido na haƙuri (yana buƙatar haɓakawa da kwanciyar hankali).
• Jirgin Sama & Tsaro:
  • Haɓaka yanayin zafi a cikin matsanancin yanayi (radiation, saurin hawan zafi mai zafi).
• Madaidaicin Kayan aiki:
  • Kayan aikin dakin gwaje-gwaje, ingantaccen tsarin kula da yanayin zafi.

2. Chips Electrode na Azurfa

• Lantarki na Mabukaci:
  • Kariyar zafin baturi a cikin wayoyin hannu, kwamfyutocin tafi-da-gidanka (mai tsadar farashi, mahalli masu laushi).
• Kayan Aikin Gida:
  • Kula da yanayin zafi a cikin na'urorin sanyaya iska, firji, masu dumama ruwa.
• Haske & LED:
  • Kariyar zafi mai zafi a cikin tsarin hasken wuta mai tsada.
• Kayayyakin Masana'antu Masu Ƙarshen Ƙarshe:
  • Wuraren da ba a buƙata ba (misali, ƙananan motoci, adaftar wutar lantarki).

III. La'akari da Tsabar Kudi da Kawowa

• Gold Electrodes:Babban farashin kayan (zinariya shine ~ 70-80 × farashi fiye da azurfa), amma tsayayyen matakai da yawan amfanin ƙasa suna ba da tabbacin amfani da su a cikin ƙananan ƙima, aikace-aikacen ƙima.
• Azurfa Electrodes:Ƙananan farashin kayan, dace da samar da taro, amma yana iya buƙatar suturar anti-oxidation (misali, nickel plating), ƙara haɓaka masana'antu.

IV. Takaitawa da Shawarwari

• Zabi Gold Electrodesdon: Babban zafin jiki, ɓarna, ko aikace-aikace masu aminci (motoci, likitanci, sararin samaniya).
• Zaɓan Electrodes na Azurfadon: Ƙididdiga mai ƙima, aikace-aikacen muhalli mai sauƙi tare da matsakaicin buƙatun rayuwa (na'urorin lantarki, kayan aiki).

Ta hanyar daidaita buƙatun aiki, yanayin muhalli, da ƙuntatawa na kasafin kuɗi, za a iya zaɓar mafi kyawun nau'in lantarki don aikace-aikacen ku.
