| Zusammenfassung: | The utility model relates to a ceramic pressure sensor with high overload performance, which belongs to an integrative ceramic pressure sensor. A circular ceramic elastic sheet and a circular ring-shaped ceramic base are crossed and connected into a whole, and the surface of the circular ceramic elastic sheet is provided with an extensometer bridge. The utility model is characterized in that the crossing and connecting point of the circular ceramic elastic sheet and the circular ring-shaped ceramic base is a cambered surface, particularly an ellipsoidal surface, the inner wall surface of the circular ring-shaped ceramic base is a conical surface, so pressure on the circular ceramic elastic sheet is transferred and dispersed along the cambered surface without generating stress concentration and forming shearing force, therefore the overload capacity of the ceramic pressure sensor can be enhanced from 2 to 3.5 times. |
