An apparatus and associated method is disclosed for assessing remaining carry cover thickness of a steel cord conveyor belt (1) without interrupting normal operations. The apparatus is positioned adjacent to a tail pulley (2) at an unloaded point. The apparatus uses ultrasonic or inductive sensors (9) for measuring remaining cover thickness as claimed in Australian Patent Application No. 2012 216 769. The sensors (9) are mounted on a carriage (7) that is driven along a linear slide (3) by a servo motor (16), and scan in a direction transverse to the operating belt (1), the scan sweeping out a zig-zag path along the belt due to lateral belt wander and longitudinal motion. The carriage (7) is controlled by a microprocessor (20), which receives and records signals from the remaining cover thickness sensors (9), a carriage absolute displacement sensor (14), a belt lateral position indicator (21), a belt speed tachometer (22), a splice detector (23), and a belt section RFID reader (35). The recorded signals are analysed to correlate sensor readings with lateral and longitudinal positions on the belt (1) and its constituent belt sections. Related readings are then averaged into representative profiles of remaining cover thickness, and used, inter alia, for forecasting serviceable belt life. 5004N-AU 2/d 0- |
