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(wàn)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(chēng)阻值相比較，如果所測(cè)阻值比原確定阻值或標(biāo)稱(chēng)阻值增大許多，甚至指針不動(dòng)（阻值趨向無(wú)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(lái)。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(chēng)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，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(wú)屏蔽罩，安裝位置周?chē)鸁o(wú)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，這就避免了相互耦合的影響。?？照{(diào)傳感器線圈，無(wú)錫東英電子有限公司。安徽傳感器線圈現(xiàn)貨</p><p

根據(jù)法拉第電磁感應(yīng)定律，當(dāng)塊狀導(dǎo)體置于交變磁場(chǎng)或在固定磁場(chǎng)中運(yùn)動(dòng)時(shí)，導(dǎo)體內(nèi)產(chǎn)生感應(yīng)電流，此電流在導(dǎo)體內(nèi)閉合，稱(chēng)為渦流。電渦流式傳感器，將位移、厚度、材料損傷等非電量轉(zhuǎn)換為電阻抗的變化（或電感、Q值的變化），從而進(jìn)行非電量的測(cè)量。一、工作原理電渦流式傳感器由傳感器激勵(lì)線圈和被測(cè)金屬體組成。根據(jù)法拉第電磁感應(yīng)定律，當(dāng)傳感器激勵(lì)線圈中通過(guò)以正弦交變電流時(shí)，線圈周?chē)鷮a(chǎn)生正選交變磁場(chǎng)，是位于蓋磁場(chǎng)中的金屬導(dǎo)體產(chǎn)生感應(yīng)電流，該感應(yīng)電流又產(chǎn)生新的交變磁場(chǎng)。新的交變磁場(chǎng)阻礙原磁場(chǎng)的變化，使得傳感器線圈的等效阻抗發(fā)生變化。傳感器線圈受電渦流影響時(shí)的等效阻抗Z為式中，ρ為被測(cè)體的電阻率；μ為被測(cè)體的磁導(dǎo)率；r為線圈與被測(cè)體的尺寸因子；f為線圈中激磁電流的頻率；x為線圈與導(dǎo)體間的距離。由此可見(jiàn)，線圈阻抗的變化完全取決于被測(cè)金屬的電渦流效應(yīng)，分別與以上因素有關(guān)。如果只改變式中的一個(gè)參數(shù)，保持其他參數(shù)不變，傳感器線圈的阻抗Z就只與該參數(shù)有關(guān)，如果測(cè)出傳感器線圈阻抗的變化，就可以確定該參數(shù)。在實(shí)際應(yīng)用中，通常是改變線圈與導(dǎo)體間的距離x，而保持其他參數(shù)不變，來(lái)實(shí)現(xiàn)位移和距離測(cè)量。二、等效電路討論電渦流式傳感器時(shí)。安徽傳感器線圈現(xiàn)貨</p><p
