Abstract: A force transducer for measuring compression and/or tension forces includes a rod-shaped deformation body and at least four strain transducers applied on the deformation body and configured for measuring a longitudinal strain and a transverse strain of the deformation body. Front and rear elongate recesses are provided on the front and rear sides of the deformation body at an intersection point between a central longitudinal axis and a central transverse axis of the deformation body. Left and right upper indentations and left and right lower indentations are provided on the deformation body respectively at the four quadrants bounded by the axes. An angle between the central transverse axis and a shortest connecting line between the front elongate recess and the left upper indentation is at least 17° and at most 29°.

Abstract: A force transducer for measuring compression and/or tension forces includes a rod-shaped deformation body and at least four strain transducers applied on the deformation body and configured for measuring longitudinal and transverse strains thereof. Front and rear elongate recesses are provided on the front and rear sides of the deformation body in the area of an intersection between a central longitudinal axis and a central transverse axis of the deformation body. Left and right upper indentations and left and right lower indentations are provided on the deformation body respectively at the four quadrants bounded by the axes. A ratio of a cross-section on a center plane extending orthogonally to the central longitudinal axis and including the central transverse axis, to a sum of first and second partial regions of the cross-section, is from 1.56 to 2.15.

Abstract: The present invention relates to a force transducer for measuring compression and/or tension forces, that comprises a rod-shaped deformation body with at least a front side (103), a rear side (104), a left side (105), a right side (106), an upper end face and a lower end face, as well as at least four strain transducers (117, 121), that are applied on the deformation body and configured and set-up for measuring a longitudinal strain and a transverse strain of the deformation body. A front elongate recess (109) is provided on the front side (103) in the area of an intersection point (S) between a central longitudinal axis and a central transverse axis (Q1) of the deformation body. Lying opposite the front elongate recess (109), a rear elongate recess (110) is provided on the rear side. At least a left upper indentation is provided above the central transverse axis (Q1) and a left lower indentation is provided below the central transverse axis (Q1) on the left side (105).

Abstract: The present invention relates to a force transducer (101) for measuring compression and/or tension forces, that comprises a rod-shaped deformation body (102) with at least a front side (103), a rear side, a left side (105), a right side (106), an upper end face (107) and a lower end face (108) as well as at least four strain transducers (117, 118, 119), that are applied on the deformation body (102) and configured and set-up for measuring a longitudinal strain and a transverse strain of the deformation body (102). A front elongate recess (109) is provided on the front side (103) in the area of an intersection point (S) between a central longitudinal axis (L) and a central transverse axis (Q1) of the deformation body (102). Lying opposite the front elongate recess (109), a rear elongate recess is provided on the rear side.

Abstract: A measuring pick-up or load cell shall be made less sensitive against off-center load applications, if necessary. At least it must be made certain that the off-center load sensitivity is within a permissible tolerance range. For this purpose the sensor body (1A, 1', SB) of the detector (1) to which there is applied at least one pick-up element or strain gage (5), is held for each load application in a different fixed position in a mounting (2) in such a way that, spaced from the clamping position a test load can be applied in a direction deviating from the direction and/or position of the axis of symmetry (CA, AS) of the sensor body (1A, 1', SB). The test loads may be uniform or they may differ for one or more load application points. A respective output signal is measured and correlated to the applied test load. At least one additional test load of the same size is applied in a different load application direction, and the respective output signal is again measured and correlated to the second test load.
