Underground pipeline detector can quickly and accurately detect the position, direction and depth of underground water pipeline, metal pipeline and cable, and the position and size of the damage point of steel pipeline anticorrosion coating without damaging the ground. It is one of the necessary instruments for water supply company, gas company, railway communication, industrial and mining, infrastructure construction unit to transform, maintain and survey underground pipelines.
The underground pipeline detector is a high-tech product based on the principle of electromagnetic induction, combined with digital filtering, wireless reception and software control.
Electromagnetic induction: Its basic working principle is: Electric and magnetic wave generated by the pipeline detector transmitter and the transmission connection by different ways to send signals to the underground metal pipe line being detected, underground metal pipeline after induction to the electromagnetic wave, surface induced current in underground metal pipelines, induced current will be along the metal line spread into the distance, in the process of current transmission, It will radiate electromagnetic wave to the ground through the underground metal pipeline, so that the receiver of underground pipeline detector will receive electromagnetic wave signal on the ground directly above the underground metal pipeline when it is detected on the ground, and the position and direction of underground metal pipeline can be determined by the change of the strength of the received signal.
This principle is realized under the following conditions: first, there must be a signal source that can generate enough electric energy to form a current in the line with electric energy transmission, and the current generates a magnetic field around the line in the process of flow;
Second, we need circuits that can receive this particular magnetic field and display the changes in the magnetic field in the form of electrical signals.
