methods to reduce the meßfehlers of scherbalkentyp - kraftaufnehmern, load cells, scherbalkentyp with reduced measurement error

摘要

A strain gage force measuring transducer is described in which distortion of measurements of a given strain on a given surface due to the interaction between the given strain and a second strain is eliminated by making a combined measurement of both strains on that same surface, equating the measured value of the second strain with the value of the distortion, and entering the so measured and equated value of the second strain into the combined measurement with a sign opposite to the sign of the distortion so as to cancel same. In a typical use, a shear beam shear-type transducer having a high degree of point-of-load insensitivity is provided thereby.
