(IMAGE) Saarland University Caption Changing the oil in hard-to-access industrial equipment, such as offshore wind turbines, is complex and costly. But by using an in-built measurement system developed by researchers at Saarland University together with partners from academia and industry, the optimum time for the oil change can now be predicted even for such remote industrial installations. Professor Andreas Schütze (left) and graduate engineer Eliseo Pignanelli (right) will be exhibiting the portable version of their measurement system at HANNOVER MESSE, with which they can perform local on-site testing to detect signs of oil aging and degradation. The oil flows through the measuring cell (center) where it is irradiated with a laser and with infrared light.
