Abstract: Disclosed is a pressure sensor containing: (1) a mechanical assembly, consisting of a bellows-pivot arrangement such as to yield a torque about a single sensitive axis wherein pressure is applied to the bellows, and (2) the appropriate electronics, consisting of a detection device to sense angular motion and a torquing device to restore the mechanical assembly to its null position. The amount of electrically generated torque necessary to balance the pressure induced torque is proportional to and a measure of the applied pressure.
