所繞的線圈的圈數(shù)我們一般把它稱為線圈的“匝數(shù)“。主要性能指標(biāo)電感線圈的性能指標(biāo)主要就是電感量的大小。另外，繞制電感線圈的導(dǎo)線一般來說總具有一定的電阻，通常這個電阻是很小的，可以忽略不記。但當(dāng)在一些電路中流過的電流很大時線圈的這個很小的電阻就不能忽略了，因為很大的電流會在這個線圈上消耗功率，引起線圈發(fā)熱甚至燒壞，所以有些時候還要考慮線圈能承受的電功率。電感量電感量L表示線圈本身固有特性，與電流大小無關(guān)。除專門的電感線圈（色碼電感）外，電感量一般不專門標(biāo)注在線圈上，而以特定的名稱標(biāo)注。電感量也稱自感系數(shù)，是表示電感器產(chǎn)生自感應(yīng)能力的一個物理量。電感器電感量的大小，主要取決于線圈的圈數(shù)（匝數(shù)）、繞制方式、有無磁心及磁心的材料等等。通常，線圈圈數(shù)越多、繞制的線圈越密集，電感量就越大。有磁心的線圈比無磁心的線圈電感量大；磁心導(dǎo)磁率越大的線圈，電感量也越大。電感量的基本單位是亨利（簡稱亨），用字母"H"表示。常用的單位還有毫亨（mH）和微亨（μH），它們之間的關(guān)系是：1H=1000mH1mH=1000μH感抗電感線圈對交流電流阻礙作用的大小稱感抗XL，單位是歐姆,符號Ω。常開傳感器線圈，無錫東英電子有限公司。</p><div

電渦流測量原理是一種非接觸式測量原理。這種類型的傳感器特別適合測量快速的位移變化，且無需在被測物體上施加外力。而非接觸測量對于被測表面不允許接觸的情況，或者需要傳感器有超長壽命的應(yīng)用領(lǐng)用意義重大。嚴(yán)格來講，電渦流測量原理應(yīng)該屬于一種電感式測量原理。電渦流效應(yīng)源自振蕩電路的能量。而電渦流需要在可導(dǎo)電的材料內(nèi)才可以形成。給傳感器探頭內(nèi)線圈提供一個交變電流，可以在傳感器線圈周圍形成一個磁場。如果將一個導(dǎo)體放入這個磁場，根據(jù)法拉第電磁感應(yīng)定律，導(dǎo)體內(nèi)會激發(fā)出電渦流。根據(jù)楞茲定律，電渦流的磁場方向與線圈磁場正好相反，而這將改變探頭內(nèi)線圈的阻抗值。而這個阻抗值的變化與線圈到被測物體之間的距離直接相關(guān)。傳感器探頭連接到控制器后，控制器可以從傳感器探頭內(nèi)獲得電壓值的變化量，并以此為依據(jù)，計算出對應(yīng)的距離值。電渦流測量原理可以運用于所有導(dǎo)電材料。由于電渦流可以穿透絕緣體，即使表面覆蓋有絕緣體的金屬材料，也可以作為電渦流傳感器的被測物體。獨特的圈式繞組設(shè)計在實現(xiàn)傳感器外形緊湊的同時，可以滿足其運轉(zhuǎn)于高溫測量環(huán)境的要求。所有德國米銥的電渦流傳感器都可以承受有灰塵，潮濕，油污和壓力的測量環(huán)境。盡管如此。汽車傳感器線圈芯，無錫東英電子有限公司。官方授權(quán)經(jīng)銷傳感器線圈原理</p><p
