Abstract

A means of increasing the useful range of pressure sensing diaphragms is developed. This is done by considering certain variable thickness plates as potential diaphragms and attempting to maximize deflection without causing other performance characteristics to differ appreciably from those of a uniform thickness plate. A thickness variation which is simple to manufacture is found and optimum geometric parameters are determined. Results are presented in the form of a series of equations which are convenient for use by the instrument designer.
