Abstract

An elongated sensor is provided for detecting the presence of a liquid in an electronics system. The sensor includes an elongated sensor element having a pair of adjacent electrical conductors, and a liquid permeable material that when dry electrically insulates the conductors, and when wet with a liquid at any point along the length of the conductors allows electric coupling of the conductors. The sensor also includes a detector operable to detect the presence of the liquid by sensing the electrical coupling of the conductors.
