根據(jù)法拉第電磁感應定律，當塊狀導體置于交變磁場或在固定磁場中運動時，導體內(nèi)產(chǎn)生感應電流，此電流在導體內(nèi)閉合，稱為渦流。電渦流式傳感器，將位移、厚度、材料損傷等非電量轉換為電阻抗的變化（或電感、Q值的變化），從而進行非電量的測量。一、工作原理電渦流式傳感器由傳感器激勵線圈和被測金屬體組成。根據(jù)法拉第電磁感應定律，當傳感器激勵線圈中通過以正弦交變電流時，線圈周圍將產(chǎn)生正選交變磁場，是位于蓋磁場中的金屬導體產(chǎn)生感應電流，該感應電流又產(chǎn)生新的交變磁場。新的交變磁場阻礙原磁場的變化，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的等效阻抗Z為式中，ρ為被測體的電阻率；μ為被測體的磁導率；r為線圈與被測體的尺寸因子；f為線圈中激磁電流的頻率；x為線圈與導體間的距離。由此可見，線圈阻抗的變化完全取決于被測金屬的電渦流效應，分別與以上因素有關。如果只改變式中的一個參數(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，如果測出傳感器線圈阻抗的變化，就可以確定該參數(shù)。在實際應用中，通常是改變線圈與導體間的距離x，而保持其他參數(shù)不變，管道傳感器線圈現(xiàn)貨，來實現(xiàn)位移和距離測量，管道傳感器線圈現(xiàn)貨，管道傳感器線圈現(xiàn)貨。二、等效電路討論電渦流式傳感器時。高速傳感器線圈芯，無錫東英電子有限公司。管道傳感器線圈現(xiàn)貨</p><div
