地(di)下(xia)管道走向和深度探測的原理(li)：
發(fa)射機產(chan)生電(dian)(dian)(dian)、磁(ci)(ci)波(bo)并通過(guo)不(bu)同的(de)發(fa)射連(lian)接(jie)(jie)方式將(jiang)發(fa)送信號(hao)(hao)傳送到地(di)(di)下(xia)被(bei)探測金(jin)屬(shu)管道(dao)上，地(di)(di)下(xia)金(jin)屬(shu)管道(dao)感(gan)應到電(dian)(dian)(dian)磁(ci)(ci)波(bo)后，在管道(dao)表(biao)面(mian)產(chan)生感(gan)應電(dian)(dian)(dian)流，感(gan)應電(dian)(dian)(dian)流就會(hui)沿著(zhu)金(jin)屬(shu)管線向(xiang)(xiang)遠處(chu)傳播，在電(dian)(dian)(dian)流的(de)傳播過(guo)程中(zhong)，又會(hui)通過(guo)該地(di)(di)下(xia)管道(dao)向(xiang)(xiang)地(di)(di)面(mian)輻射出電(dian)(dian)(dian)磁(ci)(ci)波(bo)，這樣當管道(dao)防(fang)腐層檢測儀接(jie)(jie)收機在地(di)(di)面(mian)探測時，就會(hui)在地(di)(di)下(xia)金(jin)屬(shu)管線正上方的(de)地(di)(di)面(mian)接(jie)(jie)收到電(dian)(dian)(dian)磁(ci)(ci)波(bo)信號(hao)(hao)，通過(guo)接(jie)(jie)收到的(de)信號(hao)(hao)強(qiang)弱變化就能判別地(di)(di)埋金(jin)屬(shu)管線的(de)位置和(he)走向(xiang)(xiang)。
探測(ce)地下(xia)管(guan)道防腐層(ceng)破(po)損點的原理： 
此方(fang)法又(you)稱作人體感應電容法，其原理(li)是：防(fang)腐檢測(ce)儀(yi)向(xiang)地(di)(di)(di)下管道發送(song)特定的高頻(pin)調(diao)制(zhi)信(xin)號，在地(di)(di)(di)下管道防(fang)腐層破損點處與(yu)大地(di)(di)(di)形(xing)成(cheng)回路，并向(xiang)地(di)(di)(di)面輻(fu)射泄漏電流(liu)，在破損正上方(fang)泄露輻(fu)射信(xin)號強(qiang)，根據這(zhe)一原理(li)找出管道防(fang)腐層的破損點。
