Abstract
A belt monitoring system employs a belt having at least one reinforcement member made from a conductive reinforcement material. A belt monitor is disposed in conjunction with the belt. The belt monitor comprises a field inductor excited by an applied signal. An electrical characteristic of at least a portion of the field inductor as influenced by changes in the electrical properties of the conductive reinforcement member is monitored in order to determine a physical condition of the conductive reinforcement member and thereby monitor a physical characteristic of the belt. This monitoring may be carried out by a sense inductor disposed adjacent or in conjunction with the field inductor.
