Nanjing Times TUP Underground Pipeline Detector

The Nanjing Times TUP buried pipeline detector sends electromagnetic wave signals to underground pipelines. The detector uses the principle that when the probe is perpendicular to the magnetic field lines and the ground plane, the received signal is small (almost zero) to determine the direction and depth of the pipeline. The inspector holds a probe and sends an AC signal source to the underground pipeline. When the anti-corrosion layer of the underground pipeline is corroded, the metal part of the pipeline is short circuited with the ground, forming a current circuit at the leakage point. The generated leakage point signal is radiated to the ground, and the radiation signal is * large directly above the leakage point. Based on this principle, the leakage point can be accurately found..
