Abstract
1,231,109. Pressure transducers. INSTITUT FUR REGELUNGSTECHNIK. April 17, 1969, No.19629/69. Heading G1N. A corrugated, circular, metal diaphragm 4, Fig. for measuring pressure has a flat, circumferential margin 5 partly for clamping between parts 1, 2 of the housing and partly for locating a piezoresistive element 6 Fig.3 on each side, between insulating coatings 8, 9. Each element 6 may be in two equal sections so that the four sections can form a bridge network.
