Abstract
A pressure sensor for sensing a pressure of a fluid includes a Bourdon tube that has a helical segment and an anvil. A portion of the anvil is positioned within the helical segment. The sensor also includes a dielectric material positioned between the portion of the anvil and the helical segment. The anvil, the dielectric material, and the helical segment form a variable capacitor. A capacitance of the variable capacitor changes based on a pressure applied to the Bourdon tube.
