一、金屬探測器工作原理是什么
金(jin)(jin)屬探(tan)測器(qi)是一種探(tan)測金(jin)(jin)屬的(de)(de)(de)(de)儀器(qi)，可應(ying)用(yong)于多個領域，它的(de)(de)(de)(de)工(gong)作原理是利用(yong)的(de)(de)(de)(de)電(dian)(dian)磁(ci)(ci)感(gan)應(ying)的(de)(de)(de)(de)原理，利用(yong)有交流電(dian)(dian)通(tong)過的(de)(de)(de)(de)線圈(quan)，產生(sheng)迅(xun)速變化的(de)(de)(de)(de)磁(ci)(ci)場。這個磁(ci)(ci)場能在金(jin)(jin)屬物體內部(bu)能感(gan)生(sheng)渦(wo)電(dian)(dian)流。渦(wo)電(dian)(dian)流又(you)會(hui)產生(sheng)磁(ci)(ci)場，倒過來影(ying)響(xiang)原來的(de)(de)(de)(de)磁(ci)(ci)場，引(yin)發(fa)探(tan)測器(qi)發(fa)出鳴聲。工(gong)作時(shi)，其內部(bu)探(tan)測器(qi)會(hui)發(fa)出某一頻率(lv)的(de)(de)(de)(de)電(dian)(dian)磁(ci)(ci)波，由于金(jin)(jin)屬有自感(gan)，會(hui)使(shi)這一頻率(lv)發(fa)生(sheng)偏(pian)(pian)移，當(dang)它再接(jie)收到(dao)有偏(pian)(pian)差(cha)的(de)(de)(de)(de)電(dian)(dian)磁(ci)(ci)波時(shi)，就(jiu)把差(cha)頻放大，發(fa)出信號報警。
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
一般(ban)來說，市面(mian)上(shang)的(de)(de)(de)金屬(shu)(shu)探(tan)測(ce)(ce)器(qi)(qi)的(de)(de)(de)探(tan)測(ce)(ce)范圍(wei)受(shou)到品牌(pai)、型號、探(tan)測(ce)(ce)物大小(xiao)等(deng)多種(zhong)因(yin)素(su)影響，手持金屬(shu)(shu)探(tan)測(ce)(ce)器(qi)(qi)一般(ban)是(shi)1至(zhi)40cm左右，探(tan)盤式地下(xia)(xia)金屬(shu)(shu)探(tan)測(ce)(ce)器(qi)(qi)一般(ban)是(shi)1-15m左右，遠(yuan)程地下(xia)(xia)金屬(shu)(shu)探(tan)測(ce)(ce)器(qi)(qi)是(shi)1至(zhi)30米(mi)深。以上(shang)所說的(de)(de)(de)是(shi)理論(lun)上(shang)的(de)(de)(de)測(ce)(ce)量距離，在實際使用(yong)過程中，可能會受(shou)到被探(tan)金屬(shu)(shu)的(de)(de)(de)面(mian)積、形狀(zhuang)、重(zhong)量，土質情況，金屬(shu)(shu)埋藏時(shi)間，使用(yong)者(zhe)的(de)(de)(de)技術(shu)經驗等(deng)因(yin)素(su)影響，探(tan)測(ce)(ce)距離有(you)所不同。
