Experimental acquisition of spatially distributed parameters in large scale vessels and containers is of great interest for investigation and optimization of plants and processes such as stirred tanks, chemical reactors or bioreactors.For the measurement of process parameters in a stirred fermentation biogas reactor we developed the concept of neutrally buoyant self-powered sensor particles. The prototype sensor performs logging of temperature, absolute pressure and 3D-acceleration data and is integrated in a robust capsule which gives a balance between buoyancy and gravitation with respect to the liquid process substrate. In an initial test of the developed prototype its autonomous operation has been successfully proved showing feasibility for future application in a biogas reactor.

Abstract:In the automation and control systems, sensor systems at the head, which is a direct effect on the measurement, and according to certain rules to be measured is converted into the same kind of money or other kinds of output, fast and accurate access to information and can withstand the harsh environment test, it is mechatronic systems achieve a high level of assurance. Without these sensors and system status information accurate and reliable automatic detection, information processing and decision-making functions of the system control can't be achieved. With the progress and development of sensor products, industrial monitoring and control system established by the sensor can solve problems that result from changes in the environment caused by uncertainties, thus reducing the production of wood products to improve work efficiency. Wireless sensor networks in the field of industrial control the development process, technical characteristics, common technology, application examples and problems should pay attention to choose to use are described.

Abstract.A concept for buoyancy control and magnetic position detection has been developed for the improvement of instrumented flow-following sensor particles. The sensor particles are used for investigation of hydrodynamic and biochemical processes in large-scale vessels such as biogas fermenters, bioreactors and aerated sludge basins. Neutral buoyancy of the sensor particles is required for tracing of the fluid flows. Buoyancy control is performed by adjustment of the sensor particles' volume, which is altered by an integrated piston. A miniaturized linear actuator, namely a stepper motor with linear transmission, is operated by a microcontroller to drive the piston. The buoyancy control unit enables accurate automated taring of the sensor particles in the stagnant process fluid to achieve neutral buoyancy. Therefore, the measured vertical position of the sensor particle as a function of the hydrostatic pressure is used as feedback. It has an incremental density change of 0.0136 % as compared to water and a residual drift velocity of approximately 3.6 × 10 −3 m s −1 . Furthermore, a minimum density of 926 kg m −3 can be set by full extension of the piston, which allows floating of the sensor particles after a defined event, namely critical charge of battery, full data storage or the end of a fixed time cycle. Thus, recovery of the sensor particles can proceed easily from the fluid level. The sensor particles with a buoyancy control unit are tested for depths up to 15 m. Also, detection of a local magnetic position marker by the sensor particles has been implemented to enhance movement tracking. It was tested in a lab-scale biogas digester and was used for estimation of the liquid circulation time distribution and Peclét number to describe the macro-flow.
