Subsite Pipe and Cable Locators

Radio-Detection-Metal-DetectorsAs a transmitter emits electromagnetic waves, a magnetic field is generated.

If a metal pipe or a cable is laid within the magnetic field, induced current (signal current) is produced and flows through the underground metal pipe or cable according to the principle of electromagnetic induction.

Then, a receiver picks up the magnetic field generated by the subsurface metal pipe or cable.

The location and depth of the subsurface pipe or cable is located by the angle of the magnetic force concentrically generated by the metal pipe and the strength of the magnetic field.
