With the paper “Innovative sensor technology for flange gasket monitoring”, the CiS Research Institute will present developments and proposed solutions for safety-relevant bolted joints at the 37th Pipeline Technology Symposium in Dortmund on March 22, 2023.
In the session “Equipment in plant engineering”, Dr. Thomas Frank, head of the MEMS department, and Dr. Klaus Ettrich, head of the MEMS business unit, will explain in their presentation how silicon-based MEMS sensors are used to check safety-relevant bolted joints. In this process, mechanical stresses induced in the bolt head by the pretensioning force are detected. After an introduction to how MEMS sensors work, the necessary assembly and connection technology will be presented, followed by an outline of future development trends.
The Piping Technology Conference is a platform for all industrial piping professionals as well as customers in the field of conventional power plant construction or chemical industry. This year, the motto of the conference is “Pipelines in Climate Change”. In addition to geopolitical challenges, the main focus will be on components and equipment under the influence of digitalization and hydrogen. Under the influence of hydrogen, many materials tend to become brittle and therefore require special monitoring, for example with innovative sensor technology from the CiS Research Institute.
