    用電磁感應(yīng)原理將兩個平面型繞組之間的相對位移轉(zhuǎn)換成電信號的測量元件,用于長度測量工具。感應(yīng)同步器(俗稱編碼器、光柵尺)分為直線式和旋轉(zhuǎn)式兩類。前者由定尺和滑尺組成,用于直線位移測量;后者由定子和轉(zhuǎn)子組成,用于角位移測量。1957年美國的R.W.特利普等在美國取得感應(yīng)同步器的專利,原名是位置測量變壓器,感應(yīng)同步器是它的商品名稱,初期用于雷達(dá)天線的定位和自動跟蹤、導(dǎo)彈的導(dǎo)向等。在機(jī)械制造中,感應(yīng)同步器常用于數(shù)字控制機(jī)床、加工中心等的定位反饋系統(tǒng)中和坐標(biāo)測量機(jī)、鏜床等的測量數(shù)字顯示系統(tǒng)中。它對環(huán)境條件要求較低,能在有少量粉塵、油霧的環(huán)境下正常工作?!《ǔ呱系倪B續(xù)繞組的周期為2毫米。滑尺上有兩個繞組,其周期與定尺上的相同,但相互錯開1/4周期(電相位差90°)。感應(yīng)同步器的工作方式有鑒相型和鑒幅型的兩種。前者是把兩個相位差90°、頻率和幅值相同的交流電壓U1 和U2分別輸入滑尺上的兩個繞組,按照電磁感應(yīng)原理,定尺上的繞組會產(chǎn)生感應(yīng)電勢U。如滑尺相對定尺移動,則U的相位相應(yīng)變化,經(jīng)放大后與U1和U2比相、細(xì)分、計數(shù),即可得出滑尺的位移量。在鑒幅型中,輸入滑尺繞組的是頻率、相位相同而幅值不同的交流電壓,根據(jù)輸入和輸出電壓的幅值變化,也可得出滑尺的位移量。由感應(yīng)同步器和放大、整形、比相、細(xì)分、計數(shù)、顯示等電子部分組成的系統(tǒng)稱為感應(yīng)同步器測量系統(tǒng)。它的測長精確度可達(dá)3微米/1000毫米,測角精度可達(dá)1″/360°。

    1.接近開關(guān)的選型
         對于不同的材質(zhì)的檢測體和不同的檢測距離,應(yīng)選用不同類型的接近開關(guān),以使其在系統(tǒng)中具有高的性能價格比,為此在選型中應(yīng)遵循以下原則:   1.1.當(dāng)檢測體為金屬材料時,應(yīng)選用高頻振蕩型接近開關(guān),該類型接近開關(guān)對鐵鎳、A3鋼類檢測體檢測最靈敏。   對鋁、黃銅和不銹鋼類檢測體,其檢測靈敏度就低。   1.2.當(dāng)檢測體為非金屬材料時,如;木材、紙張、塑料、玻璃和水等,應(yīng)選用電容型接近開關(guān)。   1.3.金屬體和非金屬要進(jìn)行遠(yuǎn)距離檢測和控制時,應(yīng)選用光電型接近開關(guān)或超聲波型接近開關(guān)。   1.4.對于檢測體為金屬時,若檢測靈敏度要求不高時,可選用價格低廉的磁性接近開關(guān)或霍爾式接近開關(guān)。
    2.接近開關(guān)技術(shù)指標(biāo)檢測
    2.1.動作距離測定;當(dāng)動作片由正面靠近接近開關(guān)的感應(yīng)面時,使接近開關(guān)動作的距離為接近開關(guān)的最大動作距離,測得的數(shù)據(jù)應(yīng)在產(chǎn)品的參數(shù)范圍內(nèi)。   2.2.釋放距離的測定;當(dāng)動作片由正面離開接近開關(guān)的感應(yīng)面,開關(guān)由動作轉(zhuǎn)為釋放時,測定動作片離開感應(yīng)面的最大距離。   2.3.回差H的測定;最大動作距離和釋放距離之差的絕對值。   2.4.動作頻率測定;用調(diào)速電機(jī)帶動膠木圓盤,在圓盤上固定若干鋼片,調(diào)整開關(guān)感應(yīng)面和動作片間的距離,約為開關(guān)動作距離的80%左右,轉(zhuǎn)動圓盤,依次使動作片靠近接近開關(guān),在圓盤主軸上裝有測速裝置,開關(guān)輸出信號經(jīng)整形,接至數(shù)字頻率計。此時啟動電機(jī),逐步提高轉(zhuǎn)速,在轉(zhuǎn)速與動作片的乘積與頻率計數(shù)相等的條件下,可由頻率計直接讀出開關(guān)的動作頻率。  MICROSONAR系列 接近開關(guān)
    2.5.重復(fù)精度測定;將動作片固定在量具上,由開關(guān)動作距離的120%以外,從開關(guān)感應(yīng)面正面靠近開關(guān)的動作區(qū),運(yùn)動速度控制在0.1mm/s上。當(dāng)開關(guān)動作時,讀出量具上的讀數(shù),然后退出動作區(qū),使開關(guān)斷開。如此重復(fù)10次,最后計算10次測量值的最大值和最小值與10次平均值之差,差值大者為重復(fù)精度誤差.
