Abstract:
A pressure sensor with double measuring scale includes: a flexible body designed to undergo deflection as a function of a the pressure; piezoresistive transducers for detecting the deflection; a first focusing region designed to concentrate, during a first operating condition, a first value of the pressure in a first portion of the flexible body so as to generate a deflection of the first portion of the flexible body; and a second focusing region designed to concentrate, during a second operating condition, a second value of said pressure in a second portion of the flexible body so as to generate a deflection of the second portion of the flexible body. The piezoresistive transducers correlate the deflection of the first portion of the flexible body to the first pressure value and the deflection of the second portion of the flexible body to the second pressure value.
