Online Thickness Tester

Fenner Dunlop Online Thickness Tester for conveyor belts.

The Online Belt Thickness Tester is a device which uses airborne ultrasonic probes to measure the wear profile of the cover rubber of a conveyor belt.

By tracking wear over time, an accurate life prediction can be made, giving more certainty as to when conveyor belts 'wear out'.  Additionally, by detecting premature wear, issues with the conveyor belt interacting with conveyor componentry can be identified and rectified before they become a major issue.


  • Works on any type of conveyor belting – Ply, Solid Woven, Steel Cord;
  • Belt can be moving or stopped;
  • Belt speeds up to 5 m/sec tested and proven;
  • Belts up to 3200 mm wide;
  • System can be permanently installed and providing up to the minute readings and information online;
  • Scheduled wear reports can be emailed, and reports generated on demand;
  • Data is always accessible via local intranet or available offsite via corporate VPN; 
  • Alternatively, we offer a service where the system can be temporarily fitted, readings retrieved, and a report provided.


  • All encompassing - the entire cover of the installed belt is profiled, providing the ability to accurately identify and measure areas of high wear;
  • Accurate - the target is 0.1 mm accuracy, exceeding most quoted hand-held measurements;
  • Timely - profiles and predictions can be completed in as little as two revolutions;
  • Cost effective - to achieve a similar output and resolution with hand-held readings is simply not feasible on even the shortest of belts.
