Abstract
A sensor includes electrodes and two enclosure portions. The electrodes have a shape to match an outer periphery of a non-metallic parent pipe. The two enclosure portions are connected by a hinge to facilitate positioning around the outer periphery of the non-metallic parent pipe. A first portion of the two enclosure portions includes a cutout electrode for surrounding a cutout space. The cutout electrode is tied to a ground to shield against signals from the cutout space. The sensor generates a signal indicative of the presence or absence of a pipe inserted within an inner periphery of the non-metallic parent pipe based on a capacitance measurement and a threshold.
