Abstract

An exemplary system includes a moveable mass. A load bearing member includes at least one electrically conductive tension member that supports a load associated with movement of the mass. An electrically conductive member is situated along a selected portion of a path of movement of the load bearing member. The electrically conductive member is not subject to a load on the tension member. A processor is configured to determine an electrical resistance of the tension member as an indicator of a condition of the tension member. The processor is configured to determine an electrical resistance of the electrically conductive member. The processor uses the determined electrical resistance of the electrically conductive member to compensate for any environmental influence on the determined electrical resistance of the tension member.
