Pressure sensing device

Abstract

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