一、金屬探測器工作原理是什么
金屬(shu)(shu)探(tan)測(ce)器是一(yi)(yi)種探(tan)測(ce)金屬(shu)(shu)的(de)(de)儀器，可應用于多個領域，它的(de)(de)工作(zuo)原理是利用的(de)(de)電(dian)(dian)(dian)磁(ci)(ci)感應的(de)(de)原理，利用有(you)交流電(dian)(dian)(dian)通過(guo)的(de)(de)線圈，產生(sheng)迅速變化的(de)(de)磁(ci)(ci)場。這個磁(ci)(ci)場能(neng)在金屬(shu)(shu)物體內部能(neng)感生(sheng)渦電(dian)(dian)(dian)流。渦電(dian)(dian)(dian)流又會產生(sheng)磁(ci)(ci)場，倒過(guo)來(lai)影(ying)響原來(lai)的(de)(de)磁(ci)(ci)場，引(yin)發(fa)探(tan)測(ce)器發(fa)出鳴聲。工作(zuo)時(shi)，其內部探(tan)測(ce)器會發(fa)出某(mou)一(yi)(yi)頻率(lv)的(de)(de)電(dian)(dian)(dian)磁(ci)(ci)波，由(you)于金屬(shu)(shu)有(you)自感，會使這一(yi)(yi)頻率(lv)發(fa)生(sheng)偏移，當它再接(jie)收(shou)到有(you)偏差的(de)(de)電(dian)(dian)(dian)磁(ci)(ci)波時(shi)，就(jiu)把差頻放大，發(fa)出信號報(bao)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(lai)說，市(shi)面(mian)上的(de)(de)(de)(de)金(jin)屬探(tan)(tan)測(ce)器的(de)(de)(de)(de)探(tan)(tan)測(ce)范圍受(shou)到品牌、型號、探(tan)(tan)測(ce)物大小等(deng)多種因素(su)影(ying)響(xiang)(xiang)，手持金(jin)屬探(tan)(tan)測(ce)器一(yi)般(ban)是(shi)1至(zhi)40cm左右(you)，探(tan)(tan)盤(pan)式地下金(jin)屬探(tan)(tan)測(ce)器一(yi)般(ban)是(shi)1-15m左右(you)，遠程地下金(jin)屬探(tan)(tan)測(ce)器是(shi)1至(zhi)30米(mi)深。以(yi)上所(suo)(suo)說的(de)(de)(de)(de)是(shi)理(li)論上的(de)(de)(de)(de)測(ce)量(liang)距(ju)離，在實際使(shi)(shi)用過程中，可能會受(shou)到被探(tan)(tan)金(jin)屬的(de)(de)(de)(de)面(mian)積、形(xing)狀、重量(liang)，土(tu)質情況，金(jin)屬埋(mai)藏時間，使(shi)(shi)用者(zhe)的(de)(de)(de)(de)技術經驗等(deng)因素(su)影(ying)響(xiang)(xiang)，探(tan)(tan)測(ce)距(ju)離有所(suo)(suo)不同。
