Abstract
An apparatus is providing for signal communication between the interior and exterior of a pipeline. A fitting is secured to the external surface of a pipeline, the fitting having a branch opening therein communicating with the pipeline interior. A plug member is sealably positioned in the branch opening, the plug member having a passageway therethrough. At least one conductor is received in the plug member passageway providing an apparatus to conduct an electrical signal from within to the exterior of the pipeline. A potting compound fills the passageway surrounding the conductor to seal the conductor in the plug against the leakage of liquids or gases.
