在實(shí)際工作中，一般不進(jìn)行這種檢測(cè)，*進(jìn)行線圈的通斷檢查和Q值的大小判斷。[1]可先利用萬用表電阻檔測(cè)量線圈的直流電阻，再與原確定的阻值或標(biāo)稱阻值相比較，如果所測(cè)阻值比原確定阻值或標(biāo)稱阻值增大許多，甚至指針不動(dòng)（阻值趨向無窮大X）可判斷線圈斷線；若所測(cè)阻值極小，則判定是嚴(yán)重短路或者局部短路是很難比較出來。這兩種情況出現(xiàn)，可以判定此線圈是壞的，不能用。如果檢測(cè)電阻與原確定的或標(biāo)稱阻值相差不大，可判定此線圈是好的。此種情況，我們就可以根據(jù)以下幾種情況，去判斷線圈的質(zhì)量即Q值的大小。線圈的電感量相同時(shí)，其直流電阻越小，Q值越高；所用導(dǎo)線的直徑越大，常開傳感器線圈芯，其Q值越大；若采用多股線繞制時(shí)，導(dǎo)線的股數(shù)越多，Q值越高；線圈骨架（或鐵芯）所用材料的損耗越小，其Q值越高。例如，高硅硅鋼片做鐵芯時(shí)，其Q值較用普通硅鋼片做鐵芯時(shí)高；線圈分布電容和漏磁越小，其Q值越高。例如，蜂房式繞法的線圈，其Q值較平繞時(shí)為高，比亂繞時(shí)也高；線圈無屏蔽罩，安裝位置周圍無金屬構(gòu)件時(shí)，其Q值較高，相反，則Q值較低。屏蔽罩或金屬構(gòu)件離線圈越近，其Q值降低越嚴(yán)重；對(duì)有磁芯的的位置要適當(dāng)安排合理；天線線圈與振蕩線圈應(yīng)相互垂直，常開傳感器線圈芯，常開傳感器線圈芯，這就避免了相互耦合的影響。。常開傳感器線圈，無錫東英電子有限公司。常開傳感器線圈芯</p><div

如圖3a所示，線圈112由pcb322的頂側(cè)上的跡線302和pcb322的底側(cè)上的跡線304形成。跡線302和跡線304通過穿過pcb322而形成的通孔306電接合。如圖3a所示，通孔306、頂側(cè)跡線302和底側(cè)跡線304被布置為允許形成余弦定向線圈112。例如，部分310和部分312允許線圈112交叉以形成環(huán)路114、環(huán)路116和環(huán)路118，同時(shí)在相交處將跡線分離。如進(jìn)一步示出的，部分314、部分316、部分318和部分320允許余弦定向線圈112覆蓋在pcb上。然而，通孔306和pcb322的相對(duì)的兩側(cè)上的跡線302和跡線304的存在降低了由線圈104檢測(cè)到的信號(hào)的有效幅度。有效地，通孔306在發(fā)射線圈106和信號(hào)線圈104之間形成間隙距離，這本身對(duì)位置定位系統(tǒng)的準(zhǔn)確性有很大的影響。這還與以下相結(jié)合：由于在pcb322的頂側(cè)和底側(cè)上都形成了信號(hào)線圈104的跡線，而導(dǎo)致的金屬目標(biāo)124和pcb322上的信號(hào)線圈104之間的有效氣隙的增加。圖3b示出另一個(gè)關(guān)于對(duì)稱性的問題，其中，發(fā)射線圈106與接收線圈104是不對(duì)稱的。在圖3b所示的情況下，接收線圈104不以發(fā)射線圈106為中心，并且形成與接收線圈104和發(fā)射線圈106的連接的跡線也不對(duì)稱。圖3c示出由發(fā)射線圈106生成的磁場(chǎng)強(qiáng)度的不均勻性。如圖3c所示。常開傳感器線圈芯工業(yè)傳感器線圈，無錫東英電子有限公司。</p><div

線圈是由導(dǎo)線一圈靠一圈地繞在絕緣管上，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(jiǎn)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)，就會(huì)在這根導(dǎo)線的周圍產(chǎn)生一定的電磁場(chǎng)，而這個(gè)電磁場(chǎng)的導(dǎo)線本身又會(huì)對(duì)處在這個(gè)電磁場(chǎng)范圍內(nèi)的導(dǎo)線發(fā)生感應(yīng)作用。對(duì)產(chǎn)生電磁場(chǎng)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(chǎng)，這個(gè)磁場(chǎng)又進(jìn)一步影響了導(dǎo)線中的電流；對(duì)處在這個(gè)電磁場(chǎng)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(hào)通過電感線圈時(shí)會(huì)遇到很大的阻力，很難通過；而對(duì)低頻信號(hào)通過它時(shí)所呈現(xiàn)的阻力則比較小，即低頻信號(hào)可以較容易的通過它。電感線圈對(duì)直流電的電阻幾乎為零。電阻，電容和電感，他們對(duì)于電路中電信號(hào)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(duì)電流信號(hào)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(jiǎn)稱為“電感”或“線圈”，用字母“L”表示。繞制電感線圈時(shí)。</p><p> 2）線圈在安裝前，要進(jìn)行外觀檢查使用前，應(yīng)檢查線圈的結(jié)構(gòu)是否牢固，線匝是否有松動(dòng)和松脫現(xiàn)象，引線接點(diǎn)有無松動(dòng)，磁芯旋轉(zhuǎn)是否靈活，有無滑扣等。這些方面都檢查合格后，再進(jìn)行安裝。（3）線圈在使用過程需要微調(diào)的，應(yīng)考慮微調(diào)方法有些線圈在使用過程中，需要進(jìn)行微調(diào)，依靠改變線圈圈數(shù)又很不方便，因此，選用時(shí)應(yīng)考慮到微調(diào)的方法。例如單層線圈可采用移開靠端點(diǎn)的數(shù)困線圈的方法，即預(yù)先在線圈的一端繞上3圈～4圈，在微調(diào)時(shí)，移動(dòng)其位置就可以改變電感量。實(shí)踐證明，這種調(diào)節(jié)方法可以實(shí)現(xiàn)微調(diào)±2%－±3%的電感量。應(yīng)用在短波和超短波回路中的線圈，常留出半圈作為微調(diào)，移開或折轉(zhuǎn)這半圈使電感量發(fā)生變化，實(shí)現(xiàn)微調(diào)。多層分段線圈的微調(diào)，可以移動(dòng)一個(gè)分段的相對(duì)距離來實(shí)現(xiàn)，可移動(dòng)分段的圈數(shù)應(yīng)為總?cè)?shù)的20%－30%。實(shí)踐證明：這種微調(diào)范圍可達(dá)10%－15%。具有磁芯的線圈，可以通過調(diào)節(jié)磁芯在線圈管中的位置，實(shí)現(xiàn)線圈電感量的微調(diào)。（4）使用線圈應(yīng)注意保持原線圈的電感量線圈在使用中，不要隨便改變線圈的形狀。大小和線圈間的距離，否則會(huì)影響線圈原來的電感量。尤其是頻率越高，即圈數(shù)越少的線圈。所以，在電視機(jī)中采用的高頻線圈。單向傳感器線圈，無錫東英電子有限公司。</p><div
