Requirements for microfluidic sensors based on ceramic technologies in high temperature chemical processes

After a short introduction into one actual development in the field of chemical reaction engineering, the requirements resulting from the application of sensors in a chemical reactor are shown. Physical quantities of interest when investigating and running chemical reactions are specified. As an example, the implementation of a multi-channel temperature sensor is described. Due to the chosen sensor technology, it was necessary to find a working combination of a chemically resistant steel and an electrically insulating glass paste. The compatibility of steel grade 1.4571 and Heraeus SD 1000 glass is shown.
