一、金屬探測器工作原理是什么
金(jin)(jin)屬(shu)(shu)(shu)探測(ce)器是一(yi)種探測(ce)金(jin)(jin)屬(shu)(shu)(shu)的(de)儀器，可應(ying)(ying)用(yong)于(yu)多個領域，它(ta)的(de)工(gong)作(zuo)(zuo)原理是利用(yong)的(de)電(dian)磁(ci)感應(ying)(ying)的(de)原理，利用(yong)有交流電(dian)通過的(de)線圈，產生(sheng)迅(xun)速變化(hua)的(de)磁(ci)場(chang)(chang)。這個磁(ci)場(chang)(chang)能在(zai)金(jin)(jin)屬(shu)(shu)(shu)物體(ti)內部能感生(sheng)渦電(dian)流。渦電(dian)流又會產生(sheng)磁(ci)場(chang)(chang)，倒(dao)過來(lai)影響原來(lai)的(de)磁(ci)場(chang)(chang)，引發(fa)探測(ce)器發(fa)出(chu)鳴聲。工(gong)作(zuo)(zuo)時，其(qi)內部探測(ce)器會發(fa)出(chu)某一(yi)頻率的(de)電(dian)磁(ci)波，由于(yu)金(jin)(jin)屬(shu)(shu)(shu)有自感，會使這一(yi)頻率發(fa)生(sheng)偏(pian)(pian)移，當它(ta)再接收到有偏(pian)(pian)差(cha)的(de)電(dian)磁(ci)波時，就把差(cha)頻放(fang)大，發(fa)出(chu)信(xin)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(yi)(yi)(yi)般來說，市面(mian)(mian)上的(de)(de)金屬(shu)(shu)探測器的(de)(de)探測范(fan)圍受(shou)到(dao)品牌、型號(hao)、探測物大小等(deng)多(duo)種因素(su)影響，手持金屬(shu)(shu)探測器一(yi)(yi)(yi)般是(shi)1至40cm左(zuo)右(you)，探盤(pan)式地(di)(di)下金屬(shu)(shu)探測器一(yi)(yi)(yi)般是(shi)1-15m左(zuo)右(you)，遠程地(di)(di)下金屬(shu)(shu)探測器是(shi)1至30米深。以上所說的(de)(de)是(shi)理(li)論(lun)上的(de)(de)測量距(ju)(ju)離，在實際使用過程中，可能會受(shou)到(dao)被探金屬(shu)(shu)的(de)(de)面(mian)(mian)積、形(xing)狀(zhuang)、重量，土質情況，金屬(shu)(shu)埋藏(zang)時間，使用者的(de)(de)技(ji)術經(jing)驗等(deng)因素(su)影響，探測距(ju)(ju)離有所不同。
