Abstract
A pressure sensing device includes a deflectable membrane structure to provide a deflection dependent output signal based on a pressure load, and a mechanical abutment structure for adjusting a spring constant of the deflectable membrane structure depending on the deflection of the deflectable membrane structure, wherein the mechanical abutment structure provides an abutting condition of the deflectable membrane structure when the deflection of the deflectable membrane structure exceeds a deflection threshold, wherein the abutting condition results in a change from a first spring constant to an increased, second spring constant of the deflectable membrane structure.
