一、金屬探測器工作原理是什么
金(jin)屬(shu)(shu)探測器是(shi)一(yi)種探測金(jin)屬(shu)(shu)的(de)儀(yi)器，可應用于(yu)多個(ge)領域，它(ta)的(de)工(gong)作原(yuan)理是(shi)利(li)用的(de)電磁感(gan)應的(de)原(yuan)理，利(li)用有(you)交流(liu)電通過的(de)線圈，產(chan)生(sheng)迅速(su)變化的(de)磁場。這個(ge)磁場能在金(jin)屬(shu)(shu)物體內(nei)部(bu)能感(gan)生(sheng)渦(wo)電流(liu)。渦(wo)電流(liu)又會產(chan)生(sheng)磁場，倒過來影(ying)響(xiang)原(yuan)來的(de)磁場，引發(fa)(fa)(fa)探測器發(fa)(fa)(fa)出鳴聲。工(gong)作時，其(qi)內(nei)部(bu)探測器會發(fa)(fa)(fa)出某一(yi)頻率的(de)電磁波(bo)，由于(yu)金(jin)屬(shu)(shu)有(you)自感(gan)，會使(shi)這一(yi)頻率發(fa)(fa)(fa)生(sheng)偏(pian)移，當它(ta)再接收到有(you)偏(pian)差的(de)電磁波(bo)時，就把(ba)差頻放大(da)，發(fa)(fa)(fa)出信號報警(jing)。
二、金屬探測器價格一般是多少
金屬探測器有多種類型，常見的一般主要是手持式金屬探測器和金屬探測門，金屬探測安檢門的價格主要與它的品牌、元器件、探測性能、靈敏度等方面有關，正常一般在三四千元一臺左右，中等水平的可能要貴一些，五六千元也可以搞定，再好一點的就要上萬元的。相比金屬探測安檢門，手持式金屬探測器的價格要便宜一些，通常五六十元就能買到，好一點的也有一兩百元一個的。如果您想購買金屬探測器，可以先來了解一下金屬探測器十大品牌。
三、金屬探測器能探多少米
一般來說，市面上的(de)(de)金屬(shu)(shu)探(tan)(tan)測器的(de)(de)探(tan)(tan)測范(fan)圍受到品牌、型(xing)號、探(tan)(tan)測物大(da)小(xiao)等多(duo)種因素影響，手持金屬(shu)(shu)探(tan)(tan)測器一般是(shi)1至(zhi)(zhi)40cm左(zuo)右，探(tan)(tan)盤式地(di)下(xia)金屬(shu)(shu)探(tan)(tan)測器一般是(shi)1-15m左(zuo)右，遠程地(di)下(xia)金屬(shu)(shu)探(tan)(tan)測器是(shi)1至(zhi)(zhi)30米深。以上所說的(de)(de)是(shi)理論上的(de)(de)測量距離，在實際(ji)使用(yong)過程中，可能會受到被探(tan)(tan)金屬(shu)(shu)的(de)(de)面積(ji)、形狀、重量，土質情況，金屬(shu)(shu)埋藏時間，使用(yong)者的(de)(de)技術經驗等因素影響，探(tan)(tan)測距離有所不同(tong)。
