Absolute pressure sensors in CERMET thick film technology

Different requirements of the application of pressure sensors need also different technologies and designs of realisation. The main topic of the paper shows the development of relative and absolute pressure sensor for automotives. The design and technology is focused on thick film technology with Al₂O₃ ceramics. The realised prototypes especially of absolute pressure sensors were investigated in function and some aspects of quality and of reliability. The results have shown a good suitability for the application goals. This paper is a co-operation between the AB Elektronik Sachsen GmbH and the University of Applied Sciences HTW Dresden with Libor Janovsky ´s work as a guest student from the CVUT Prague at the HTW Dresden.
