A new sensor system developed in Saarbrücken, Germany can not only carefully control drying processes in industrial ovens, but can deliver reliable air humidity measurements even at high temperatures and in the presence of other background vapours. Professor Andreas Schütze, project manager Tilman Sauerwald and their research team at Saarland University have developed with partner companies a sensor system that precisely monitors industrial drying, baking and cooking processes. The new system improves product quality, optimizes the production process and lowers process energy demands. The project has received funding from the Federal Ministry of Education and Research’s priority funding programme “KMU-Innovativ’ that promotes innovative technology in small and medium-sized enterprises.
