1. A health monitoring system for an electrically-conductive tension member of an elevator system belt, comprising:
a transmitter including a transmitter coil configured for placement at the tension member;
a receiver configured to be positioned at the tension member; and
a controller operably connected to the transmitter and the receiver, the controller configured to:
direct an alternating current through the transmitter coil, resulting in the generation of a magnetic field and eddy currents at the transmitter coil; and
evaluate fluctuations in the magnetic field detected at the receiver, the fluctuations indicative of wear or damage to the tension member;
wherein the controller is configured to obtain position information from an elevator control system to locate and map locations of wear or damage of the tension member;
wherein the transmitter and the receiver are disposed at a same side of the tension member; and
wherein a position of the receiver is offset from a position of the transmitter relative to a lengthwise direction of the tension member.
