一、金屬探測器工作原理是什么

金屬(shu)探(tan)測(ce)器是一(yi)(yi)種探(tan)測(ce)金屬(shu)的(de)儀器，可應用(yong)于(yu)多個領域(yu)，它的(de)工(gong)作(zuo)原理(li)是利(li)用(yong)的(de)電(dian)磁感(gan)應的(de)原理(li)，利(li)用(yong)有(you)交流(liu)電(dian)通(tong)過(guo)的(de)線圈，產生(sheng)(sheng)迅速變化(hua)的(de)磁場。這個磁場能(neng)在金屬(shu)物體(ti)內(nei)部能(neng)感(gan)生(sheng)(sheng)渦(wo)電(dian)流(liu)。渦(wo)電(dian)流(liu)又會(hui)產生(sheng)(sheng)磁場，倒過(guo)來影響(xiang)原來的(de)磁場，引發(fa)探(tan)測(ce)器發(fa)出(chu)鳴聲。工(gong)作(zuo)時，其內(nei)部探(tan)測(ce)器會(hui)發(fa)出(chu)某一(yi)(yi)頻(pin)率的(de)電(dian)磁波(bo)，由(you)于(yu)金屬(shu)有(you)自感(gan)，會(hui)使這一(yi)(yi)頻(pin)率發(fa)生(sheng)(sheng)偏移，當它再接收到有(you)偏差的(de)電(dian)磁波(bo)時，就把差頻(pin)放大(da)，發(fa)出(chu)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(yi)般(ban)來說(shuo)，市(shi)面上的金(jin)屬(shu)探(tan)測(ce)(ce)器的探(tan)測(ce)(ce)范圍受到(dao)品牌、型(xing)號(hao)、探(tan)測(ce)(ce)物大(da)小(xiao)等多種因(yin)素影響(xiang)，手持(chi)金(jin)屬(shu)探(tan)測(ce)(ce)器一(yi)般(ban)是1至40cm左右，探(tan)盤式地下金(jin)屬(shu)探(tan)測(ce)(ce)器一(yi)般(ban)是1-15m左右，遠程地下金(jin)屬(shu)探(tan)測(ce)(ce)器是1至30米深。以上所(suo)(suo)說(shuo)的是理論上的測(ce)(ce)量距離(li)(li)，在實際(ji)使用過程中，可能會受到(dao)被探(tan)金(jin)屬(shu)的面積、形狀、重量，土質情況，金(jin)屬(shu)埋藏時間，使用者的技術經驗等因(yin)素影響(xiang)，探(tan)測(ce)(ce)距離(li)(li)有所(suo)(suo)不同。

四、金屬探測制作方法

了(le)解了(le)金屬(shu)探(tan)(tan)(tan)(tan)測器的(de)(de)(de)(de)(de)部(bu)件和原理，我們也(ye)(ye)可(ke)(ke)以(yi)自(zi)己制(zhi)(zhi)(zhi)(zhi)(zhi)作(zuo)一個(ge)金屬(shu)探(tan)(tan)(tan)(tan)測器，自(zi)制(zhi)(zhi)(zhi)(zhi)(zhi)金屬(shu)探(tan)(tan)(tan)(tan)測器并不難，用自(zi)制(zhi)(zhi)(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)和收音(yin)(yin)機(ji)(ji)就可(ke)(ke)以(yi)完成(cheng)，具體的(de)(de)(de)(de)(de)制(zhi)(zhi)(zhi)(zhi)(zhi)作(zuo)方法是：1、繞制(zhi)(zhi)(zhi)(zhi)(zhi)探(tan)(tan)(tan)(tan)測線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)：金屬(shu)探(tan)(tan)(tan)(tan)測器的(de)(de)(de)(de)(de)探(tan)(tan)(tan)(tan)測線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)分為(wei)兩部(bu)分，分別起到發(fa)射和接(jie)(jie)收信號的(de)(de)(de)(de)(de)作(zuo)用：發(fa)射線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)即探(tan)(tan)(tan)(tan)測線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)的(de)(de)(de)(de)(de)外(wai)環線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)，接(jie)(jie)收線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)即探(tan)(tan)(tan)(tan)測線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)的(de)(de)(de)(de)(de)內(nei)環線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)，由另一組導(dao)線(xian)(xian)(xian)(xian)繞成(cheng)的(de)(de)(de)(de)(de)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)組成(cheng)。從夾板上(shang)裁(cai)下兩個(ge)環，一個(ge)環大小(xiao)如餐盤，另一個(ge)如小(xiao)碟，最終小(xiao)的(de)(de)(de)(de)(de)那個(ge)要(yao)能(neng)夠套在大的(de)(de)(de)(de)(de)里面。再裁(cai)幾條木(mu)條將大環和小(xiao)環連(lian)接(jie)(jie)起來，大小(xiao)環就像靶(ba)子上(shang)的(de)(de)(de)(de)(de)同(tong)心圓一樣。制(zhi)(zhi)(zhi)(zhi)(zhi)作(zuo)大小(xiao)兩個(ge)同(tong)心圓支架可(ke)(ke)以(yi)選用木(mu)質支架或(huo)者PVC材料完成(cheng)制(zhi)(zhi)(zhi)(zhi)(zhi)作(zuo)，在外(wai)環線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)上(shang)繞10~50圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)0.25毫米線(xian)(xian)(xian)(xian)徑的(de)(de)(de)(de)(de)漆包(bao)銅(tong)線(xian)(xian)(xian)(xian)，內(nei)環線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)也(ye)(ye)如此，當然，如果(guo)你手頭恰巧沒有0.25mm線(xian)(xian)(xian)(xian)徑的(de)(de)(de)(de)(de)漆包(bao)線(xian)(xian)(xian)(xian)，也(ye)(ye)可(ke)(ke)以(yi)使用其他線(xian)(xian)(xian)(xian)徑型號的(de)(de)(de)(de)(de)漆包(bao)線(xian)(xian)(xian)(xian)。在完成(cheng)探(tan)(tan)(tan)(tan)測線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)的(de)(de)(de)(de)(de)制(zhi)(zhi)(zhi)(zhi)(zhi)作(zuo)后，需要(yao)注(zhu)意(yi)保護繞制(zhi)(zhi)(zhi)(zhi)(zhi)好的(de)(de)(de)(de)(de)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)(quan)，使用PVC外(wai)殼或(huo)者其他方式進(jin)行外(wai)殼的(de)(de)(de)(de)(de)保護安裝(zhuang)。2、制(zhi)(zhi)(zhi)(zhi)(zhi)作(zuo)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)臺：要(yao)做(zuo)(zuo)一個(ge)最基(ji)本的(de)(de)(de)(de)(de)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)臺，只需要(yao)把AM收音(yin)(yin)機(ji)(ji)用作(zuo)探(tan)(tan)(tan)(tan)測頭和揚聲器就可(ke)(ke)以(yi)了(le)。把AM收音(yin)(yin)機(ji)(ji)的(de)(de)(de)(de)(de)頻率(lv)調(diao)(diao)到最高，注(zhu)意(yi)不要(yao)調(diao)(diao)到某個(ge)頻道上(shang)。3、連(lian)接(jie)(jie)連(lian)接(jie)(jie)桿：隨(sui)便找根長桿，底部(bu)連(lian)接(jie)(jie)探(tan)(tan)(tan)(tan)測頭，頂部(bu)連(lian)接(jie)(jie)收音(yin)(yin)機(ji)(ji)做(zuo)(zuo)成(cheng)的(de)(de)(de)(de)(de)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)臺，中間留出手能(neng)握住的(de)(de)(de)(de)(de)空間就可(ke)(ke)以(yi)了(le)。
