Abstract
The protection against interference with methods and means of determining the location of underground cables and pipelines and the main stages of the development of induction track finders has been analyzed. Theoretically, the informative features of the distribution of the magnetic field differential current conductors for the choice of the difference magnetosensor of small-scale track finders protected from external field are investigated.
It is found that for the difference magnetosensors orthogonal to the base, the profiling function has a maximum signal over the current conductor. For the difference magnetosensors parallel to the base there is a clear minimum of the signal over the current conductor between the two maxima located at a distance equal to the depth of the current conductor. Such differential magnet sensors are suitable for determining the location and depth of the underground pipeline, with the removal of the influence of an external almost homogeneous obstacle-causing magnetic field.
