Pressure sensing device

A pressure sensing device comprising:

• a deflectable membrane structure configured to provide a deflection dependent output signal based on a pressure load;
• a mechanical abutment structure for adjusting a spring constant of the deflectable membrane structure depending on the deflection of the deflectable membrane structure;
• and
• a counter structure arranged vertically opposite to the deflectable membrane structure,
• wherein the mechanical abutment structure comprises a plurality of bumps, which are fixed to the deflectable membrane structure between the deflectable membrane structure and the counter structure,
• wherein the mechanical abutment structure further comprises a counter bump, which is fixed to the counter structure between the deflectable membrane structure and the counter structure, and which is aligned with a bump of the plurality of bumps to form an aligned counter bump,
• wherein the mechanical abutment structure is configured to provide a first abutting condition of the deflectable membrane structure via the aligned counter bump, when the deflection of the deflectable membrane structure exceeds a first deflection threshold,
• wherein the first abutting condition results in a change from a first spring constant to an increased, second spring constant of the deflectable membrane structure,
• wherein the mechanical abutment structure is configured to provide a second abutting condition of the deflectable membrane structure, when the deflection of the deflectable membrane structure exceeds a second deflection threshold and a remaining bump of the mechanical abutment structure is arranged between and in mechanical contact with the deflectable membrane structure and the counter structure, and
• wherein the second abutting condition results in a change from the second spring constant to an increased, third spring constant of the deflectable membrane structure.
