A column transducer, comprising a body (6) elongated in an axial direction (A), wherein there is a measuring portion (7,7a), having measuring means (8,9; 61,62,63,64;61a,62a,63a,64a;4,45) for measuring the strain induced by the force to be measured, the measuring portion (7,7a) having a section whose width, in a plane which is orthogonal to said axial direction (A), is smaller than that of the section of the body (6) in its other parts, so as to define opposite recesses, with through holes at their longitudinal ends, comprising a tapered portion located at the two ends in the axial direction of each of the recesses, the through holes (60,65) being provided in the area of such tapered portions, leaving a region in between the tapered portions which is deliberately identified by sizes and conformations such that when the measuring means (8,9;61,62;61a,62a;44,45) are located therein and when the body (6) is subjected to the force to be measured, the stress, and therefore the strain, in the axial direction (A,A1) or a direction parallel thereto, in a given position, substantially corresponds to the stress, and therefore the strain, that is generated in a plane (A2) position. <IMAGE> |
