ABSTRACT:
A transducer including a deformation body with a strain gage produces hysteresis-affected measured values based on the strain of the deformation body. Each measured value is to be corrected by the hysteresis error. For this purpose, a hysteresis model is formed from a recorded loading characteristic curve and the theory of the dipole density of the oriented elementary dipoles in the interior of the deformation body. With the aid of the hysteresis model, and the determined hysteresis-affected measured values, and in connection with the acquired loading history, a correction value is derived and used to correct the hysteresis error.
