一、金屬探測器工作原理是什么
金屬(shu)探(tan)測器是一種探(tan)測金屬(shu)的儀器，可應用(yong)于多個(ge)領域(yu)，它的工作原(yuan)理(li)是利用(yong)的電磁(ci)(ci)感應的原(yuan)理(li)，利用(yong)有(you)(you)交流(liu)電通過的線(xian)圈，產(chan)生迅速(su)變化的磁(ci)(ci)場(chang)(chang)(chang)。這個(ge)磁(ci)(ci)場(chang)(chang)(chang)能在(zai)金屬(shu)物體內部(bu)能感生渦電流(liu)。渦電流(liu)又會產(chan)生磁(ci)(ci)場(chang)(chang)(chang)，倒過來影響原(yuan)來的磁(ci)(ci)場(chang)(chang)(chang)，引發(fa)(fa)探(tan)測器發(fa)(fa)出鳴聲。工作時，其內部(bu)探(tan)測器會發(fa)(fa)出某一頻(pin)率的電磁(ci)(ci)波，由于金屬(shu)有(you)(you)自(zi)感，會使這一頻(pin)率發(fa)(fa)生偏(pian)移(yi)，當它再接收到有(you)(you)偏(pian)差的電磁(ci)(ci)波時，就把(ba)差頻(pin)放(fang)大，發(fa)(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(lai)說，市(shi)面上(shang)的(de)金(jin)屬(shu)(shu)探(tan)(tan)(tan)(tan)測器的(de)探(tan)(tan)(tan)(tan)測范圍(wei)受到(dao)品(pin)牌、型號、探(tan)(tan)(tan)(tan)測物(wu)大小(xiao)等(deng)多種因(yin)素影(ying)響(xiang)，手持金(jin)屬(shu)(shu)探(tan)(tan)(tan)(tan)測器一般(ban)是1至(zhi)40cm左右，探(tan)(tan)(tan)(tan)盤(pan)式(shi)地下金(jin)屬(shu)(shu)探(tan)(tan)(tan)(tan)測器一般(ban)是1-15m左右，遠(yuan)程(cheng)(cheng)地下金(jin)屬(shu)(shu)探(tan)(tan)(tan)(tan)測器是1至(zhi)30米深。以上(shang)所說的(de)是理(li)論上(shang)的(de)測量距離，在實際使(shi)用過(guo)程(cheng)(cheng)中，可(ke)能會受到(dao)被探(tan)(tan)(tan)(tan)金(jin)屬(shu)(shu)的(de)面積、形狀、重(zhong)量，土質情況，金(jin)屬(shu)(shu)埋藏時間，使(shi)用者的(de)技術經驗(yan)等(deng)因(yin)素影(ying)響(xiang)，探(tan)(tan)(tan)(tan)測距離有(you)所不同。
