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，同時在相交處將跡線分離。如進一步示出的，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檢測到的信號的有效幅度。有效地，通孔306在發(fā)射線圈106和信號線圈104之間形成間隙距離，這本身對位置定位系統(tǒng)的準確性有很大的影響。這還與以下相結(jié)合：由于在pcb322的頂側(cè)和底側(cè)上都形成了信號線圈104的跡線，而導(dǎo)致的金屬目標124和pcb322上的信號線圈104之間的有效氣隙的增加。圖3b示出另一個關(guān)于對稱性的問題，其中，發(fā)射線圈106與接收線圈104是不對稱的。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稱。圖3c示出由發(fā)射線圈106生成的磁場強度的不均勻性。如圖3c所示。江蘇傳感器線圈定做比例傳感器線圈芯，無錫東英電子有限公司。</p><div

電感線圈的敏感性要通過使用單獨的前置放大線圈獲得。當然，對于弱的磁場，使用者也可以通過增加音量來彌補。但是這樣不太方便，尤其是需要經(jīng)常切換麥克風(fēng)擋和電感擋時。此外，這需要助聽器有足夠的音量保留，同時在獲得足夠的增益時不會引起嘯叫。在電感位置，如果增益太大，也會引起嘯叫。就像聲波從授話器漏回麥克風(fēng)會引起反饋一樣，磁場引起的嘯叫也是從授話器漏回到電感線圈引起的。(三)感應(yīng)線圈回路的頻率響應(yīng)助聽器通過麥克風(fēng)接收到的頻率響應(yīng)與通過感應(yīng)線圈得到的頻率響應(yīng)之間存在著匹配的問題。助聽器的響度通常都通過仔細的調(diào)整，以適合佩戴者、假沒助聽器在聲音輸入是70dBSPL時和磁場強度是100mA/m時的輸出功率是一樣的話，助聽器佩戴者就可以方便地從麥克風(fēng)擋切換到電感擋，而無需改變音量。然而感應(yīng)線圈回路和助聽器電感系統(tǒng)的頻響有時仍不能令人滿意。但回路響應(yīng)和助聽器電感響應(yīng)結(jié)合時產(chǎn)生的聲音，不能與原來的聲音響應(yīng)區(qū)別太大。只有一個例外，即500Hz以下頻率聲音的減弱，在某些情況下對某些人可能是有利的，因為這個頻率范圍是磁場干擾容易發(fā)生的。但這也是對重度聽力損失的人很重要的頻率范圍。好在多記憶助聽器可以分開調(diào)整麥克風(fēng)和電感的響應(yīng)。</p><p> 在實際工作中，一般不進行這種檢測，*進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量線圈的直流電阻，再與原確定的阻值或標稱阻值相比較，如果所測阻值比原確定阻值或標稱阻值增大許多，甚至指針不動（阻值趨向無窮大X）可判斷線圈斷線；若所測阻值極小，則判定是嚴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。如果檢測電阻與原確定的或標稱阻值相差不大，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，其直流電阻越小，Q值越高；所用導(dǎo)線的直徑越大，其Q值越大；若采用多股線繞制時，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，其Q值較用普通硅鋼片做鐵芯時高；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值較平繞時為高，比亂繞時也高；線圈無屏蔽罩，安裝位置周圍無金屬構(gòu)件時，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值降低越嚴重；對有磁芯的的位置要適當安排合理；天線線圈與振蕩線圈應(yīng)相互垂直，這就避免了相互耦合的影響。。管道傳感器線圈，無錫東英電子有限公司。</p><div

位置定位器系統(tǒng)410的準確度可以被定義為在金屬目標408從初始位置掃描到結(jié)束位置期間的位置的測量與該掃描的預(yù)期理想曲線之間的差。該結(jié)果以相對于全標度的百分比表示，如圖5所示。在圖5中，pos0是來自位置定位系統(tǒng)410的測量值，并且輸出擬合是理想曲線。pos0是從控制器402的寄存器測量的值，而fs是全標度的值。例如，對于16比特寄存器，fs為2e16-1＝65535。圖6示出通過上式確定的用fnl％fs表示的誤差。目標是以盡可能佳的準確性(例如，％fs或更小)產(chǎn)生位置感測。如果使用試錯法設(shè)計pcb上的線圈設(shè)計，則可獲得的佳準確性為％fs-3％fs。在pcb上形成的傳感器中，有兩個線圈和一個發(fā)射器線圈。測量位置的準確性與線圈設(shè)計極為相關(guān)。pcb上的試錯線圈設(shè)計已經(jīng)經(jīng)驗性地嘗試解決這些問題。然而，這種簡化但不準確的方法只能考慮有限的問題。所有這些過程都無法得到成功的設(shè)計，這是因為整個系統(tǒng)(線圈-目標-跡線)要比容易解決的更復(fù)雜，并且，如果所得到的線圈設(shè)計將滿足期望的準確性規(guī)范，則佳解決方案必須考慮更大量的參數(shù)。圖7a示出根據(jù)本發(fā)明的一些實施例的用于提供準確的位置定位系統(tǒng)的印刷電路板上的線圈設(shè)計的算法700。傳感器線圈資料，無錫東英電子有限公司。江蘇傳感器線圈定做</p><p

可以把產(chǎn)生電渦流的金屬導(dǎo)體等效成一個短路環(huán)，即假設(shè)電渦流只分布在環(huán)體內(nèi)。因此，電渦流式傳感器的等效電路計算方法為：式中，R2為電渦流短路環(huán)等效電阻；h為電渦流的深度（）；ra為短路環(huán)的外徑；ri為短路環(huán)的內(nèi)徑。由基爾霍夫電壓定律有式中ω為線圈與金屬導(dǎo)體的互感系數(shù)。可得等效阻抗為式中Req為產(chǎn)生電渦流效應(yīng)后線圈的等效電阻，Leq為產(chǎn)生電渦流效應(yīng)后線圈的等效電感。由于電渦流的影響，線圈復(fù)阻抗的實部（等效電阻）增大、虛部（等效電感）減小。因此，線圈的等效品質(zhì)因數(shù)下降。電渦流式傳感器的等效電氣參數(shù)都是互感系數(shù)M2的函數(shù)。通常總是利用其等效電感的變化組成測量電路，因此，電渦流式傳感器屬于電感式（互感式）傳感器。三、測量電路用于電渦流傳感器的測量電路主要有調(diào)頻式，調(diào)幅式測量電路兩種。1、調(diào)頻式測量電路調(diào)頻式測量電路，傳感器線圈作為組成LC振蕩器的電感元件，當傳感器等效電感在渦流影響下因被測量變化而變化時，將導(dǎo)致振蕩器的振蕩頻率發(fā)生變化，該頻率可直接由數(shù)字頻率計測得，或通過頻率-電壓變換后用數(shù)字電壓表測量出對應(yīng)的電壓。2、調(diào)幅式測量電路調(diào)幅式測量電路，由傳感器線圈、電容和石英晶體組成的石英晶體振蕩電路。官方授權(quán)經(jīng)銷傳感器線圈資料</p><p
