Abstract
A strain-gauge transducer (5) comprising a substrate (10) provided with strain gauges and pressure members (11, 12) which deform the substrate (10) via transfer elements (1a, 4a) which transmit an applied force (F). The transfer elements comprise bars (1a, 1b, 4a, 4b) molded from an elastomer in a common molding operation. A material (2a, 3a) having a higher compressibility than the bars may be interposed between the bars. This material may form elastic stops (54a) provided to preclude breakage of the substrate. This results in a transducer whose sensitivity is linear for small loads and which is very insusceptible to overloading. The transducer can be used for the construction of scales or touch tablets.
