ABSTRACT:
In a load cell, in particular for weighing systems, comprising a deformable member (1), this deformable member has an aperture (2) extending transversely of the direction of the force, which is closed by at least one disc-shaped wall which corresponds to the cross-section of the aperture and extends transversely of the axis of the aperture and serves to receive strain gauges which are deposited by means of a film technique. The deformable member is formed by two sub-members (3, 4) which are welded together in a plane which extends transversely of the axis of the aperture. A wall is provided in the aperture of each sub-member, at least one wall being provided at its interior side with strain gauges.
