【溫度感測誤差難解？這裡有好建議！】

電子產業對精度的要求越來越高，溫度感測也不例外。目前市面上具有許多溫度感測解決方案，每一種都有其優缺點。

●熱電耦：是低成本、中等精度的高溫測量方案，可測量＞1000℃ 的溫度，惟須留意「塞貝克效應」；
●電阻溫度檢測器 (RTD)：測量＜500℃ 中溫區間，提供數位輸出、無需線性化，它們具有高線性度且重複性較好，支援小封裝尺寸和低功耗，缺點是需要精確的驅動電流：偏偏連接線的電阻常導致感測器的電阻測量出現誤差；
●熱敏電阻：溫度範圍較低，優點是電阻會在小幅溫度變化下呈現大幅變化，儘管它具有非線性，仍可達到很高的精度，還能提供快速的熱回應。

特別一提，「矽晶溫度感測器」的線性度相對較高且精度遠超其他方案，甚至能實現非常高的生命體徵監測精度。不過，還有些要留意的事項……

About author
2002年，憑藉獨特敏銳度察覺到電子業界需求，《COMPOTECHAsia電子與電腦》於中國大陸取得《COMPOTECHChina》月刊發行權，為初到海外發展及當地讀者出具最具前瞻性且中肯的觀察，具有相當影響力，也成為一流國際大廠競相展示研發心血的首選。 2006年，有鑑於網路環境日趨成熟，《COMPOTECHAsia電子與電腦》再度領先同業，首創線上視頻平台CTOV (COMPOTECH Online Video)。自此，成為整合紙本、網站、電子報及線上視頻的全方位媒體。 2016年，為貫徹市場應用及開發技術的連結並擴大群眾基礎，陸續展開 Facebook、Twitter、LinkedIn 等社群平台經營。 「就市論勢、就勢論市」是我們的信念。我們將於每週一、三、五下午在 FB 分享生活中隨處可見的科普知識，以平易近人的方式，用不一樣的角度觀察市場趨勢和技術走向，並不定時穿插轉載網路精彩佳作或趣聞。記得設為「搶先看」哦！ “COMPOTECHAsia/ China” issue on 8th monthly. It is the dependent media which focuses on electronic industry situation, end user market, and technology trend. The monthly magazine has become the main channel to get professional information for engineers, purchaser, R&D employees and decision-making management. We perceived the demand of electronic industry and strive to get the distribution rights of “China Edition” in Mainland China in 2002. It gives a lot of prospective and proper observation for the overseas workers and local readers. Gradually, COMPOTECH is getting to be the powerful. Nowadays, COMPOTECH is the first-choice platform for the first-class firms to display their R&D results. Furthermore, in 2006, we were ahead of our competitors to build the CTOV platform (COMPOTECH Online Video) due to the mature internet environment. Since then, COMPOTECH has become the integrated media. For having a thorough knowledge of market applications and technology migration, as well as expanding the base of the masses, we begin to manage the Facebook, Twitter and LinkedIn etc. in 2016.
智能系統設計／應用工程師、產品／專案開發主管、元器件／零組件／準系統採購者的交流園地，於每週一、三、五下午分享【科技應用取向】的趨勢議題。
