一、金屬探測器工作原理是什么
金屬(shu)探(tan)測器是(shi)一(yi)種(zhong)探(tan)測金屬(shu)的(de)(de)儀器，可應(ying)用(yong)于(yu)多個領域，它的(de)(de)工作原(yuan)理(li)是(shi)利(li)用(yong)的(de)(de)電磁(ci)感(gan)應(ying)的(de)(de)原(yuan)理(li)，利(li)用(yong)有交流(liu)電通過(guo)的(de)(de)線圈，產(chan)生(sheng)迅速(su)變化的(de)(de)磁(ci)場(chang)。這(zhe)個磁(ci)場(chang)能在金屬(shu)物(wu)體內(nei)部(bu)能感(gan)生(sheng)渦(wo)電流(liu)。渦(wo)電流(liu)又會(hui)(hui)產(chan)生(sheng)磁(ci)場(chang)，倒過(guo)來影響原(yuan)來的(de)(de)磁(ci)場(chang)，引(yin)發探(tan)測器發出(chu)鳴(ming)聲。工作時，其(qi)內(nei)部(bu)探(tan)測器會(hui)(hui)發出(chu)某(mou)一(yi)頻率(lv)的(de)(de)電磁(ci)波，由于(yu)金屬(shu)有自感(gan)，會(hui)(hui)使這(zhe)一(yi)頻率(lv)發生(sheng)偏移，當(dang)它再(zai)接(jie)收到有偏差的(de)(de)電磁(ci)波時，就把差頻放大，發出(chu)信號報警(jing)。
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(lai)說(shuo)，市面上的(de)(de)金屬探(tan)(tan)(tan)測器的(de)(de)探(tan)(tan)(tan)測范圍受到品牌、型號、探(tan)(tan)(tan)測物大小等(deng)多種因素影(ying)響，手持金屬探(tan)(tan)(tan)測器一般是(shi)1至40cm左右(you)，探(tan)(tan)(tan)盤(pan)式地(di)(di)下金屬探(tan)(tan)(tan)測器一般是(shi)1-15m左右(you)，遠程地(di)(di)下金屬探(tan)(tan)(tan)測器是(shi)1至30米深。以(yi)上所(suo)說(shuo)的(de)(de)是(shi)理論(lun)上的(de)(de)測量(liang)距(ju)離，在實際使用過程中(zhong)，可能會受到被(bei)探(tan)(tan)(tan)金屬的(de)(de)面積、形狀、重(zhong)量(liang)，土質情況，金屬埋藏時間，使用者(zhe)的(de)(de)技術經驗(yan)等(deng)因素影(ying)響，探(tan)(tan)(tan)測距(ju)離有所(suo)不同。
