ABSTRACT:
A pressure sensor for sensing a fluid pressure in a high acceleration environment. The sensor has a chamber partially defined by a non-planar membrane, the chamber containing a fluid at a reference pressure, such that the non-planar membrane deflects due to pressure differentials between the reference pressure and the fluid pressure. The deflection is converted into an output signal indicative of the fluid pressure by associated circuitry. By keeping the area of the membrane exposed to the fluid in the chamber to less than 0.1 grams, the acceleration forces have minimal affect on the amount that membrane flexes.
