With increasing automation and demand for energy efficiency, new digital measurement solutions are more pertinent than ever for monitoring and process optimisations. Existing products based on current monitoring lack flexibility and are costly to install. Due to the operating principle, these sensors can only measure the current in a single conductor of a cable. Therefore, these systems are unsuitable for many businesses, especially for retrofits because of cost and complexity. Based on space technology deployed as part of ESA’s Rosetta Mission, PhySens GmbH developed a contactless, non-invasive and easily retrofittable sensor solution for current measurement. By simply mounting the sensor on a cable, it measures the currents in all conductors simultaneously using high-precision magnetic field data. As a result, this new sensor-solution can detect and classify anomalies in current profiles caused by e.g. faulty motors or seized bearings in hard-to-access or sealed machinery. This is vital for intelligent load management and predictive maintenance as part of industrial automation or future manned space missions.
