一、金屬探測器工作原理是什么
金(jin)(jin)屬探測器(qi)(qi)是(shi)一(yi)種(zhong)探測金(jin)(jin)屬的(de)(de)(de)儀(yi)器(qi)(qi),可應(ying)用于多(duo)個領(ling)域,它的(de)(de)(de)工(gong)作原理(li)是(shi)利用的(de)(de)(de)電(dian)(dian)磁(ci)感(gan)應(ying)的(de)(de)(de)原理(li),利用有(you)(you)交流電(dian)(dian)通過(guo)的(de)(de)(de)線(xian)圈,產生迅速變化的(de)(de)(de)磁(ci)場。這(zhe)個磁(ci)場能在金(jin)(jin)屬物體內部能感(gan)生渦(wo)電(dian)(dian)流。渦(wo)電(dian)(dian)流又(you)會(hui)產生磁(ci)場,倒過(guo)來(lai)影響原來(lai)的(de)(de)(de)磁(ci)場,引發(fa)探測器(qi)(qi)發(fa)出鳴聲。工(gong)作時(shi),其內部探測器(qi)(qi)會(hui)發(fa)出某一(yi)頻(pin)率的(de)(de)(de)電(dian)(dian)磁(ci)波,由于金(jin)(jin)屬有(you)(you)自感(gan),會(hui)使這(zhe)一(yi)頻(pin)率發(fa)生偏移,當它再接收(shou)到(dao)有(you)(you)偏差(cha)(cha)的(de)(de)(de)電(dian)(dian)磁(ci)波時(shi),就(jiu)把差(cha)(cha)頻(pin)放大,發(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(shuo)(shuo),市面上的(de)(de)金(jin)屬(shu)(shu)探(tan)(tan)測(ce)器(qi)的(de)(de)探(tan)(tan)測(ce)范圍受到品(pin)牌、型號、探(tan)(tan)測(ce)物大(da)小等多種因素(su)影響(xiang),手(shou)持金(jin)屬(shu)(shu)探(tan)(tan)測(ce)器(qi)一般是1至(zhi)40cm左(zuo)右(you)(you),探(tan)(tan)盤式地(di)(di)下金(jin)屬(shu)(shu)探(tan)(tan)測(ce)器(qi)一般是1-15m左(zuo)右(you)(you),遠程地(di)(di)下金(jin)屬(shu)(shu)探(tan)(tan)測(ce)器(qi)是1至(zhi)30米深。以上所(suo)說(shuo)(shuo)的(de)(de)是理論上的(de)(de)測(ce)量(liang)距(ju)(ju)離(li),在實際使用過程中(zhong),可(ke)能(neng)會受到被探(tan)(tan)金(jin)屬(shu)(shu)的(de)(de)面積、形狀、重量(liang),土質情況,金(jin)屬(shu)(shu)埋藏時間(jian),使用者的(de)(de)技術(shu)經(jing)驗等因素(su)影響(xiang),探(tan)(tan)測(ce)距(ju)(ju)離(li)有所(suo)不同。
