Background Composite roller developed by Narvik Composite Industrial interest in embedded condition monitoring Made possible through composite design of roller Measurement of roller parameters, e.g. bearing temperature, rotation speed, and vibration Facilitate preventive maintenance and prevent sudden failures due to roller damage, Pre-study formed base Generator integration in Roller Patent granted 2018-11-17 ITF Automationsdagar 2014

Technical challenges Harsh environment Evaluation of measurement data Magnetic, EMC, temperatures, humidity, mechanical, rotating environment Evaluation of measurement data Diagnostics based on e.g. temperature and vibration Robustness The electronics life span must exceed the expected life of roller Power supply Integration of generator in roller Network Signal transfer and multi hop networking Production Cost effective production 2018-11-17 ITF Automationsdagar 2014
