Installation of the Sensing Idler in the Rotterdam bulk goods terminal
The HBTR terminal in Rotterdam – operated by HES International – is Europe’s largest transshipment terminal for bulk materials like iron ore and coal. Its conveyor systems operate around the clock and are a critical part of the (un)loading processes. As such, unexpected downtimes are highly disruptive – particularly in the area of conveyor belts, which often act as operational bottlenecks.
As part of a pilot project, the Sensing Idler – a sensor-equipped carrying roller – was integrated into an existing conveyor system. The project is a collaboration between component manufacturer Artur Küpper GmbH & Co. KG, operator HBTR, and development partner core sensing.
Project Goals at a Glance
The aim of the collaboration is to test the system under real operating conditions and gather insights for potential future applications. The focus lies on the continuous condition monitoring of carrying rollers to detect wear at an early stage and support maintenance processes with data-driven insights. This further installation serves to jointly validate the Sensing Idler in an industrial environment.

- Continued evaluation of the Sensing Idler under real-world conditions
- Monitoring the bearing condition of individual carrying rollers to detect potential failures early
- Gathering data to support the development of condition-based maintenance strategies
- Gaining experience in the long-term use of conveyor systems
Technical Highlights of the Sensing Idler
- Measurement of bearing temperature inside the roller
- Autonomous power supply with a service life exceeding 5 years
- Solar-powered gateway for wireless connectivity
- Automatic position assignment for quick commissioning
- Mesh network architecture supporting thousands of rollers
- No system modification needed – rollers can be replaced without altering the installation
- Access to condition data via dashboard or system integration
