Abstract:
A force measuring cell comprising an essentially level and rectangular plate, which is loaded with a force to be measured in its shearing plane and which has a first circular hole through a neutral plane with respect to this force, whose axis is perpendicular to the neutral plane of the plate and in this first hole a measuring transducer is carried, whereby this first hole, by means of formation of its wall is providing means for positional and gripping force acceptance, comprising:the plate which is clamped into a base along its edge parallel to the direction of the force to be measured;the first hole which lies between the edge and impact point of the force to be measured;the measuring transducer including an oscillating string measuring transformer;the oscillating string measuring transformer having at least two force inputs;the wall of the first hole being formed in at least two positions such that the force inputs of the oscillating string measuring transformer is inserted and locked in position and a gripping force is exerted by a pre-tensioning force; andthe oscillating string measuring transformer being clamped in the first hole such that the force acting on it is essentially at 45.degree. to the direction of the force to be measured, whereby the oscillating string measuring transformer is measuring the force and deformation displacement of the wall of the first hole.
