A wireless supplied multi-sensor-system for spatial resolved inline process analysis

Large scaling industrial processes, e.g. charging or mixing, often are attended by inhomogeneities in the material composition. One vision of monitoring these processes involves autonomously moving sensors in the process volume which obtain and transmit spatially resolved data. The paper illustrates first approaches for those requests. An experimental platform is described which drives an optic, an acoustic and a dielectric sensor module via a rotating unit in the (liquid) medium. The work is focused on the realization of wireless power and data transfer and presents the conceptual design of sensor modules. First experimental results are discussed.
