Strain-gauge transducer
First Claim
1. A strain-gauge transducer comprising:
- a strain gauge enclosed between pressure members, the strain gauge including a plate-shaped substrate provided with strain-detection elements,at least one spring disposed between said substrate and one of the pressure members so as to be deformed in conjunction with said substrate by force exerted by the pressure members wherein said substrate exclusively contacts said spring in an arrangement such that the substrate is not connected to the spring, said spring having a flexibility larger than that of the substrate.

Abstract
A strain-gauge transducer comprises a strain gauge enclosed between pressure members which deform the strain gauge, the strain gauge comprising a plate-shaped substrate provided with strain-detection elements. At least one spring having a flexibility larger than that of the substrate is arranged between the strain gauge and at least one of the pressure members, said substrate and said spring being in contact with one another so as to be jointly subjected to deformations. The spring may be a blade spring, a helical spring, or a cylindrical buffer spring. The excursions of the pressure members can be limited by means of stops. In the case of a blade spring the contact between the substrate and the spring can be controlled by giving the substrate a toothed shape or by providing it with contact elements.
