Structural Analysis of a Pressure Sensor for High Temperature Environments
Publié en 2012
Pressure sensors operating at the temperature higher that 500 °C are absent in the world market. Our goal is to develop a pressure sensor that can operate at the high temperature up to 700 °C. Our sensor will be made up of a ceramic sensible element and a metallic case. The sensible element will be a ceramic beam with a Weathstone bridge on its surface. A structural analysis on the case has been performed to design the case and to study the behavior with pressure and temperature of different metallic alloys using a model reckoning with the mechanical stress due the pressure combined with the thermal expansion of the material. The stresses on the plate grow with pressure and with temperature.
