电缆警示带的探测常用的方法是电磁法。电缆警示带内夹带的金属箔，在电磁场作用下的感应电流会产生二次场。可在地面上用探测仪器探测到，以确定电缆警示带的位置。例如电磁法主动源法，信号强，定位、定深的精度高，不受临近其他管道干扰（被查电缆警示带需有露出点）。使用时发射机一端接被查踪迹带，另一端接地或接踪迹带另一端。探测仪通过探测踪迹带产生的磁感应强度的变化，确定踪迹带的空间位置。

The common method for detecting cable warning tape is electromagnetic method. The induced current of the metal foil carried in the cable warning belt under the action of electromagnetic field will produce a secondary field. It can be detected on the ground with a detection instrument to determine the position of the cable warning tape. For example, the active source method of electromagnetic method has strong signal, high accuracy of positioning and depth determination, and is not interfered by other nearby pipelines (the detected cable warning tape needs to be exposed). When in use, one end of the transmitter is connected to the detected track band, and the other end is grounded or connected to the other end of the track band. The detector determines the spatial position of the track belt by detecting the change of magnetic induction intensity generated by the track belt.
