一、金屬探測器工作原理是什么
金屬(shu)(shu)(shu)探測(ce)(ce)(ce)器是一種探測(ce)(ce)(ce)金屬(shu)(shu)(shu)的(de)儀器，可應(ying)用(yong)(yong)于(yu)多個(ge)領域，它的(de)工作(zuo)原理是利(li)用(yong)(yong)的(de)電(dian)(dian)磁(ci)(ci)感應(ying)的(de)原理，利(li)用(yong)(yong)有交流(liu)電(dian)(dian)通(tong)過(guo)的(de)線(xian)圈，產生迅速變化的(de)磁(ci)(ci)場。這個(ge)磁(ci)(ci)場能在(zai)金屬(shu)(shu)(shu)物體內部能感生渦(wo)(wo)電(dian)(dian)流(liu)。渦(wo)(wo)電(dian)(dian)流(liu)又(you)會(hui)(hui)產生磁(ci)(ci)場，倒過(guo)來影響原來的(de)磁(ci)(ci)場，引發(fa)(fa)探測(ce)(ce)(ce)器發(fa)(fa)出(chu)鳴聲。工作(zuo)時，其內部探測(ce)(ce)(ce)器會(hui)(hui)發(fa)(fa)出(chu)某一頻率的(de)電(dian)(dian)磁(ci)(ci)波，由(you)于(yu)金屬(shu)(shu)(shu)有自(zi)感，會(hui)(hui)使這一頻率發(fa)(fa)生偏移(yi)，當它再(zai)接收到有偏差的(de)電(dian)(dian)磁(ci)(ci)波時，就把差頻放大，發(fa)(fa)出(chu)信號報警。
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)般(ban)來說，市面上的金(jin)(jin)屬探(tan)(tan)測(ce)(ce)器的探(tan)(tan)測(ce)(ce)范圍(wei)受到品(pin)牌、型號、探(tan)(tan)測(ce)(ce)物大小(xiao)等多種因(yin)素(su)影(ying)響，手持(chi)金(jin)(jin)屬探(tan)(tan)測(ce)(ce)器一(yi)般(ban)是(shi)1至40cm左右，探(tan)(tan)盤式地(di)下(xia)金(jin)(jin)屬探(tan)(tan)測(ce)(ce)器一(yi)般(ban)是(shi)1-15m左右，遠程(cheng)地(di)下(xia)金(jin)(jin)屬探(tan)(tan)測(ce)(ce)器是(shi)1至30米深。以上所(suo)(suo)說的是(shi)理(li)論上的測(ce)(ce)量(liang)距離(li)，在(zai)實際使(shi)用(yong)過程(cheng)中(zhong)，可能會受到被探(tan)(tan)金(jin)(jin)屬的面積、形狀、重量(liang)，土質情況，金(jin)(jin)屬埋藏時間，使(shi)用(yong)者的技(ji)術經驗等因(yin)素(su)影(ying)響，探(tan)(tan)測(ce)(ce)距離(li)有所(suo)(suo)不同。
