電感線圈的敏感性要通過使用單獨(dú)的前置放大線圈獲得。當(dāng)然，對于弱的磁場，使用者也可以通過增加音量來彌補(bǔ)。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(xì)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(qiáng)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?yàn)檫@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> 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(jì)算出對應(yīng)的距離值。電渦流測量原理可以運(yùn)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(dú)特的圈式繞組設(shè)計(jì)在實(shí)現(xiàn)傳感器外形緊湊的同時，可以滿足其運(yùn)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。新傳感器線圈芯，無錫東英電子有限公司。</p><div
