Abstract

A position monitoring system includes a tubular with a cavity formed therein, a magnet movable relative to the tubular, and a sensor sensible of a magnetic field of the magnet. A housing positioned within the cavity sealably isolates the sensor from environmental properties while permitting the sensor to sense the magnetic field of the magnet.
