Autoclaves, self-sealing devices, are widely used in industries such as medicine, chemistry, and construction. In a specific project for the production of calcium silicate and aerated concrete, the challenge is addressed to precisely determine the optimal time to safely open the autoclave, aiming to optimize efficiency and safety. However, conventional pressure sensors in autoclaves exhibit inaccuracies due to calibration issues and deposits in the steam flow.
The project aims to develop an innovative turbine wheel sensor for autoclaves. The sensor utilizes powered coils to measure the rotational speed of the turbine wheel, which is driven by steam. By integrating actuator functions, the sensor can be self-monitoring, perform self-tests, and calibrate independently. The development includes the design of the turbine wheel, electrical connection, electronic evaluation, and method development, tested in various phases starting with a demonstration and laboratory model. The electronics are connected via shielded cables with indicator lights and a control element, requiring special protection against electromagnetic interference from three-phase and asynchronous machines. The development goes through three phases: fundamental development and design, verification of variations and optimization, and the realization of the final prototype.
The R&D project, under the ZIM funding framework, collaborates with partners MUST from TU Darmstadt and Eitner GmbH, a medium-sized company, focusing on developing new concepts specifically for small and medium-sized enterprises (SMEs). ZIM funding aims to support innovation projects for SMEs, provided by the AiF within its Research and Transfer Alliances, targeting the development of future technologies and industrial transformation with a focus on climate neutrality and sustainability.
