A resistive pressure transducer wherein a flexible diaphragm is mounted in a spaced apart relationship to the upper surface of a base member. A conductive path is deposited on one surface of the diaphragm. A resistive configuration is also deposited on the same surface of the diaphragm. The resistive configuration includes four separate resistive patterns. The first and third resistive patterns are deposited in close proximity to the outer edge of the diaphragm. The first and third resistive patterns are each comprised of three radially extending resistors, spaced apart along the periphery of the diaphragm, and interconnected by conductive material. The second and fourth resistive patterns are deposited in close proximity to the center of the diaphragm. The first and third resistive patterns measure radial strain, while the second and fourth resistive patterns measure tangential strain. The four resistive patterns each forms a separate leg of a Wheatstone bridge configuration.
