一、金屬探測器工作原理是什么
金(jin)屬(shu)探(tan)測器是一種探(tan)測金(jin)屬(shu)的(de)(de)(de)儀器,可(ke)應用(yong)于多個領域(yu),它的(de)(de)(de)工(gong)作原(yuan)理是利(li)用(yong)的(de)(de)(de)電(dian)(dian)磁(ci)感(gan)應的(de)(de)(de)原(yuan)理,利(li)用(yong)有交(jiao)流電(dian)(dian)通過的(de)(de)(de)線圈(quan),產生迅速變化的(de)(de)(de)磁(ci)場(chang)。這(zhe)個磁(ci)場(chang)能在金(jin)屬(shu)物體內部能感(gan)生渦(wo)電(dian)(dian)流。渦(wo)電(dian)(dian)流又會產生磁(ci)場(chang),倒(dao)過來影響原(yuan)來的(de)(de)(de)磁(ci)場(chang),引發探(tan)測器發出鳴聲。工(gong)作時,其內部探(tan)測器會發出某一頻(pin)率的(de)(de)(de)電(dian)(dian)磁(ci)波,由于金(jin)屬(shu)有自感(gan),會使這(zhe)一頻(pin)率發生偏移,當它再(zai)接收到有偏差的(de)(de)(de)電(dian)(dian)磁(ci)波時,就把差頻(pin)放大,發出信號報警。
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
一般來說,市面上的(de)金(jin)(jin)屬(shu)探(tan)(tan)測器(qi)(qi)的(de)探(tan)(tan)測范圍受到品牌、型號、探(tan)(tan)測物大小(xiao)等多種因(yin)素(su)(su)影響,手持金(jin)(jin)屬(shu)探(tan)(tan)測器(qi)(qi)一般是1至40cm左右(you),探(tan)(tan)盤(pan)式地下金(jin)(jin)屬(shu)探(tan)(tan)測器(qi)(qi)一般是1-15m左右(you),遠程(cheng)(cheng)地下金(jin)(jin)屬(shu)探(tan)(tan)測器(qi)(qi)是1至30米深。以上所說的(de)是理論(lun)上的(de)測量距離(li),在實際使用(yong)過程(cheng)(cheng)中,可能會受到被探(tan)(tan)金(jin)(jin)屬(shu)的(de)面積、形狀、重量,土質情況,金(jin)(jin)屬(shu)埋藏時間,使用(yong)者的(de)技術經(jing)驗等因(yin)素(su)(su)影響,探(tan)(tan)測距離(li)有(you)所不(bu)同。
