線圈是由導(dǎo)線一圈靠一圈地繞在絕緣管上，塑封傳感器線圈價(jià)格查詢，導(dǎo)線彼此互相絕緣，而絕緣管可以是空心的，也可以包含鐵芯或磁粉芯。線圈的電感用L表示，單位有亨利(H)、毫亨利(mH)、微亨利(μH)，1H=10^3mH=10^6μH。簡介電感線圈是利用電磁感應(yīng)的原理進(jìn)行工作的器件。當(dāng)有電流流過一根導(dǎo)線時(shí)，塑封傳感器線圈價(jià)格查詢，就會(huì)在這根導(dǎo)線的周圍產(chǎn)生一定的電磁場，而這個(gè)電磁場的導(dǎo)線本身又會(huì)對處在這個(gè)電磁場范圍內(nèi)的導(dǎo)線發(fā)生感應(yīng)作用。對產(chǎn)生電磁場的導(dǎo)線本身發(fā)生的作用，叫做“自感“，即導(dǎo)線自己產(chǎn)生的變化電流產(chǎn)生變化磁場，塑封傳感器線圈價(jià)格查詢，這個(gè)磁場又進(jìn)一步影響了導(dǎo)線中的電流；對處在這個(gè)電磁場范圍的其他導(dǎo)線產(chǎn)生的作用，叫做“互感“。電感線圈的電特性和電容器相反，“通低頻，阻高頻“。高頻信號通過電感線圈時(shí)會(huì)遇到很大的阻力，很難通過；而對低頻信號通過它時(shí)所呈現(xiàn)的阻力則比較小，即低頻信號可以較容易的通過它。電感線圈對直流電的電阻幾乎為零。電阻，電容和電感，他們對于電路中電信號的流動(dòng)都會(huì)呈現(xiàn)一定的阻力，這種阻力我們稱之為“阻抗”。電感線圈對電流信號所呈現(xiàn)的阻抗利用的是線圈的自感。電感線圈有時(shí)我們把它簡稱為“電感”或“線圈”，用字母“L”表示。繞制電感線圈時(shí)。耐磨傳感器線圈，無錫東英電子有限公司。塑封傳感器線圈價(jià)格查詢</p><div

例如，目標(biāo)的角位置可以被計(jì)算為：角位置＝arctan(vsin/vcos)。圖2e示出了這一點(diǎn)，并且示出vcos和vsin的正弦形式以及根據(jù)vcos和vsin的值得出的對金屬目標(biāo)124的位置的確定。在線性位置定位系統(tǒng)中，可以通過知道線圈104的跡線的正弦形式的波長(即，正弦定向線圈112的跡線和余弦定向線圈110的跡線的峰距區(qū)域之間的間隔)，通過角位置來確定線性位置。在角位置定位系統(tǒng)中，正弦定向線圈112和余弦定向線圈110可以被布置為使得該角位置可以等于關(guān)于金屬目標(biāo)124的旋轉(zhuǎn)的金屬目標(biāo)124的實(shí)際角位置。重要的是要注意指示位置定位傳感器100的理想操作的以下條件。在那些條件中，發(fā)射器線圈106的形狀不重要，只要其覆蓋放置線圈104的區(qū)域即可。此外，線圈104的形狀等于完美的幾何重疊的正弦和余弦。另外，金屬目標(biāo)124的形狀對工作原理沒有影響，只要目標(biāo)的區(qū)域覆蓋線圈104的總區(qū)域的一部分即可。理想的一組線圈和理想的金屬目標(biāo)的這些條件從未被滿足。在實(shí)際系統(tǒng)中，情況大不相同。非理想性導(dǎo)致金屬目標(biāo)124的位置的確定的不準(zhǔn)確性。導(dǎo)致位置確定的不正確性的問題包括發(fā)射線圈106中生成的電磁場的不均勻。</p><p> 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(gè)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(shí)線圈的這個(gè)很小的電阻就不能忽略了，因?yàn)楹艽蟮碾娏鲿?huì)在這個(gè)線圈上消耗功率，引起線圈發(fā)熱甚至燒壞，所以有些時(shí)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(gè)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。冰箱傳感器線圈芯，無錫東英電子有限公司。</p><div
