ABSTRACT:
A sensor body for use in a pig for determining characteristics of a pipeline wall though which the pig passes includes a circuit board and a single coil wrapped around the circuit board. A microcontroller is mounted to the circuit board and connected to the single coil and configured to induce a waveform on the coil to thereby create an eddy current in the pipeline wall adjacent the sensor body. The microcontroller is also configured to measure changes in a characteristic of the induced waveform on the single coil that correspond to the presence of anomalies on an inside diameter of the pipeline wall. The sensor body also includes a sensor body cover molded about the circuit board, the microcontroller and the single coil. The sensor body cover consists essentially of a wear resistant, non-conductive material that includes a polymer material.
