Patent abstract
A pressure sensor for sensing a fluid pressure in harsh environments such as the air pressure in a tire, by using a chamber partially defined by a flexible membrane (20), the chamber containing a fluid at a reference pressure, such that the flexible membrane (20) deflects due to pressure differentials between the reference pressure and the fluid pressure; and,associated circuitry for converting the deflection of the flexible membrane (20) into an output signal indicative of the fluid pressure; wherein,the membrane (20) is non-planar (22, 24).
