Pipe and Cable Locator (PCL)
A Pipe and Cable Locator (PCL) can be invaluable when it comes to finding underground pipes and cables. The device puts off an electromagnetic frequency that can push through the ground to bounce off of any of the pipes or similar materials that are buried below. When searching for water pipes, the device is connected to a valve or hydrant.
A current flowing along a conductor creates a magnetic field. The field forms a cylindrical shape around the conductor and is called “alteration current (a.c) or signal”. The locators detect the magnetic field around the conductor (cable or pipe line). Pipe and Cable Locator (PCL) can locate any kind of cables or some kinds of metallic pipes.
