Abstract

A sensor for measuring pressure and/or force includes at least one measuring assembly having at least one piezoelectric measuring element subjected to compressive stress for dynamic pressure and/or force measurement, and a diaphragm for introducing the pressure and/or the force onto at least the piezoelectric measuring element. The sensor also includes a further measuring assembly that is based on a different physical measuring principle for measuring static pressure and/or force.
