1,183,659. Resistance strain gauges. CESKOSLOVENSK‡ AKADEMIE V•D. Oct.3, 1968 [Oct.9, 1967], No.46910/68. Heading G1N. A circular diaphragm for measuring fluidpressure is formed from a variable thickness material e.g. varying linearly from circumference to centre, and has four resistance strain gauges bonded symmetrically on the surface. The arrangement is said to increase the sensitivity. |
