一、金屬探測器工作原理是什么

金(jin)屬(shu)(shu)探測器(qi)是(shi)一種探測金(jin)屬(shu)(shu)的(de)(de)(de)儀器(qi)，可應(ying)用于(yu)多個領域(yu)，它的(de)(de)(de)工作(zuo)原理(li)是(shi)利用的(de)(de)(de)電(dian)(dian)(dian)磁(ci)(ci)感(gan)應(ying)的(de)(de)(de)原理(li)，利用有(you)交流(liu)電(dian)(dian)(dian)通過的(de)(de)(de)線圈，產(chan)生(sheng)迅(xun)速變化的(de)(de)(de)磁(ci)(ci)場。這(zhe)個磁(ci)(ci)場能(neng)(neng)在(zai)金(jin)屬(shu)(shu)物體內部能(neng)(neng)感(gan)生(sheng)渦電(dian)(dian)(dian)流(liu)。渦電(dian)(dian)(dian)流(liu)又(you)會(hui)產(chan)生(sheng)磁(ci)(ci)場，倒過來(lai)影響原來(lai)的(de)(de)(de)磁(ci)(ci)場，引發(fa)(fa)探測器(qi)發(fa)(fa)出鳴聲。工作(zuo)時，其內部探測器(qi)會(hui)發(fa)(fa)出某(mou)一頻率的(de)(de)(de)電(dian)(dian)(dian)磁(ci)(ci)波，由于(yu)金(jin)屬(shu)(shu)有(you)自感(gan)，會(hui)使(shi)這(zhe)一頻率發(fa)(fa)生(sheng)偏(pian)(pian)移，當(dang)它再接收到有(you)偏(pian)(pian)差(cha)的(de)(de)(de)電(dian)(dian)(dian)磁(ci)(ci)波時，就把差(cha)頻放(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)來說，市(shi)面上的金(jin)(jin)屬(shu)探(tan)(tan)測器(qi)的探(tan)(tan)測范(fan)圍受到(dao)品牌、型(xing)號(hao)、探(tan)(tan)測物大小等多種因素影響(xiang)，手持金(jin)(jin)屬(shu)探(tan)(tan)測器(qi)一般(ban)是(shi)1至40cm左右，探(tan)(tan)盤式(shi)地(di)下(xia)金(jin)(jin)屬(shu)探(tan)(tan)測器(qi)一般(ban)是(shi)1-15m左右，遠程地(di)下(xia)金(jin)(jin)屬(shu)探(tan)(tan)測器(qi)是(shi)1至30米深(shen)。以上所說的是(shi)理(li)論上的測量(liang)距離，在實際使用過程中，可能會受到(dao)被探(tan)(tan)金(jin)(jin)屬(shu)的面積、形(xing)狀、重量(liang)，土質情況，金(jin)(jin)屬(shu)埋(mai)藏時(shi)間，使用者(zhe)的技術經驗(yan)等因素影響(xiang)，探(tan)(tan)測距離有(you)所不同(tong)。

四、金屬探測制作方法

了解了金屬(shu)(shu)探(tan)(tan)(tan)測器(qi)的(de)(de)(de)(de)(de)(de)部(bu)件和原(yuan)理，我們也(ye)(ye)可(ke)以(yi)(yi)自(zi)己(ji)制(zhi)作一(yi)(yi)個(ge)(ge)金屬(shu)(shu)探(tan)(tan)(tan)測器(qi)，自(zi)制(zhi)金屬(shu)(shu)探(tan)(tan)(tan)測器(qi)并不難，用自(zi)制(zhi)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)和收(shou)(shou)(shou)音(yin)機(ji)(ji)(ji)就(jiu)可(ke)以(yi)(yi)完(wan)成(cheng)(cheng)，具(ju)體的(de)(de)(de)(de)(de)(de)制(zhi)作方法是(shi)：1、繞(rao)制(zhi)探(tan)(tan)(tan)測線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)：金屬(shu)(shu)探(tan)(tan)(tan)測器(qi)的(de)(de)(de)(de)(de)(de)探(tan)(tan)(tan)測線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)分(fen)為(wei)兩(liang)部(bu)分(fen)，分(fen)別起到(dao)(dao)發(fa)射和接收(shou)(shou)(shou)信號(hao)的(de)(de)(de)(de)(de)(de)作用：發(fa)射線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)即探(tan)(tan)(tan)測線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)(de)(de)外(wai)環線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)，接收(shou)(shou)(shou)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)即探(tan)(tan)(tan)測線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)(de)(de)內(nei)環線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)，由(you)另一(yi)(yi)組(zu)導線(xian)(xian)(xian)(xian)(xian)繞(rao)成(cheng)(cheng)的(de)(de)(de)(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)組(zu)成(cheng)(cheng)。從夾板上裁下兩(liang)個(ge)(ge)環，一(yi)(yi)個(ge)(ge)環大(da)小如(ru)(ru)餐盤，另一(yi)(yi)個(ge)(ge)如(ru)(ru)小碟(die)，最終小的(de)(de)(de)(de)(de)(de)那個(ge)(ge)要(yao)能夠(gou)套在大(da)的(de)(de)(de)(de)(de)(de)里面。再裁幾(ji)條木(mu)條將大(da)環和小環連接起來(lai)，大(da)小環就(jiu)像靶子(zi)上的(de)(de)(de)(de)(de)(de)同(tong)心圓一(yi)(yi)樣。制(zhi)作大(da)小兩(liang)個(ge)(ge)同(tong)心圓支架可(ke)以(yi)(yi)選用木(mu)質支架或(huo)者(zhe)PVC材料完(wan)成(cheng)(cheng)制(zhi)作，在外(wai)環線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)上繞(rao)10~50圈(quan)(quan)(quan)0.25毫(hao)米(mi)線(xian)(xian)(xian)(xian)(xian)徑的(de)(de)(de)(de)(de)(de)漆(qi)包銅線(xian)(xian)(xian)(xian)(xian)，內(nei)環線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)也(ye)(ye)如(ru)(ru)此，當然，如(ru)(ru)果你手(shou)頭恰巧沒(mei)有0.25mm線(xian)(xian)(xian)(xian)(xian)徑的(de)(de)(de)(de)(de)(de)漆(qi)包線(xian)(xian)(xian)(xian)(xian)，也(ye)(ye)可(ke)以(yi)(yi)使用其(qi)他線(xian)(xian)(xian)(xian)(xian)徑型號(hao)的(de)(de)(de)(de)(de)(de)漆(qi)包線(xian)(xian)(xian)(xian)(xian)。在完(wan)成(cheng)(cheng)探(tan)(tan)(tan)測線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)(de)(de)制(zhi)作后(hou)，需(xu)要(yao)注(zhu)意保護(hu)繞(rao)制(zhi)好的(de)(de)(de)(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)，使用PVC外(wai)殼或(huo)者(zhe)其(qi)他方式進(jin)行外(wai)殼的(de)(de)(de)(de)(de)(de)保護(hu)安裝。2、制(zhi)作控(kong)制(zhi)臺(tai)：要(yao)做一(yi)(yi)個(ge)(ge)最基本的(de)(de)(de)(de)(de)(de)控(kong)制(zhi)臺(tai)，只需(xu)要(yao)把AM收(shou)(shou)(shou)音(yin)機(ji)(ji)(ji)用作探(tan)(tan)(tan)測頭和揚(yang)聲器(qi)就(jiu)可(ke)以(yi)(yi)了。把AM收(shou)(shou)(shou)音(yin)機(ji)(ji)(ji)的(de)(de)(de)(de)(de)(de)頻率調到(dao)(dao)最高，注(zhu)意不要(yao)調到(dao)(dao)某個(ge)(ge)頻道上。3、連接連接桿：隨便找根(gen)長桿，底部(bu)連接探(tan)(tan)(tan)測頭，頂部(bu)連接收(shou)(shou)(shou)音(yin)機(ji)(ji)(ji)做成(cheng)(cheng)的(de)(de)(de)(de)(de)(de)控(kong)制(zhi)臺(tai)，中(zhong)間留出手(shou)能握住的(de)(de)(de)(de)(de)(de)空間就(jiu)可(ke)以(yi)(yi)了。
