Autonomous sensor particle for parameter tracking in large vessels

Thiele, S.; Da Silva, M. J.; Hampel, U.


We developed a neutrally buoyant self-powered sensor particle for the measurement of spatially distributed process parameters in large vessels. One intended application is the measurement of flow parameters in stirred fermentation biogas reactors. The prototype sensor particle is a robust and neutrally buoyant capsule with integrated measurement electronics which performs logging of temperature, absolute pressure (immersion depth) and 3D-acceleration data. In an initial flow experiment the autonomous operation of the developed prototype was successfully proven, showing feasibility for future application in fermentation reactors and other industrial processes.
