【正文】 and generalpurpose electromechanical of the traditional potentiometes are contacttype ponent,there are many defects with order to overe these defects,the noncontact potentiometers are design is on the base of modern sensor a Profound understanding of the modern sensor technology,I use a suited sensor to achieveing the “noncontact”.Not only I analyse the theory,but also I think over the practical setting,I choose the differentialinductive sensors as the modulatory terminal,and mend the sensor circuit,so the stability and susceptiveness have improved. In the output of the potentiometer,I use a operational amplifier to increase the output the test of this work,I prove it meet the design requirements: achieveing the “noncontact” of the potentiometer.keywords：potentiometer，noncontact potentiometers，sensor technology， differentialinductive sensors，operational amplifier目 錄 摘 要 ……………………………………………………………1ABSTRACT ……………………………………………………… 2引 言 …………………………………………………………… 4第一章 設(shè)計任務(wù)………………………………………………… 5 設(shè)計題目………………………………………………… 5 設(shè)計背景………………………………………………… 5 設(shè)計任務(wù)………………………………………………… 5第二章 電位器的認識…………………………………………… 6 傳統(tǒng)電位器……………………………………………… 6 非接觸式電位器………………………………………… 7第三章 傳感器的電子學基礎(chǔ)…………………………………… 8 電橋……………………………………………………… 8 電橋的電源……………………………………………… 10 傳感器信號的放大……………………………………… 11第四章 作品設(shè)計………………………………………………… 12結(jié) 語 …………………………………………………………… 19參考文獻 ………………………………………………………… 21后 記 …………………………………………………………… 22致 謝 …………………………………………………………… 22引 言電位器是一種可調(diào)的電子元件。當電阻體的兩個固定觸電之間外加一個電壓時，通過轉(zhuǎn)動或滑動系統(tǒng)改變觸點
