Abstract

In order, in a weighing device, in particular for use in high-resolution scales, comprising an elastically deformable force transducer, a sensor arrangement for converting the deformation of the force transducer caused on account of a force F acting on the force input section of the force transducer into an electrical weighing signal and a processing unit for calculating a weighing signal corrected by the hysteresis error of the force transducer, to be able to realize a correction of the hysteresis error even with the short-term load variations occurring in practice in high-resolution scales at an acceptable cost, it is suggested that the sensor arrangement comprise a first testing unit for the high-resolution determination of the weighing signal 'S' and a second testing unit for the determination of the elastic deformation of the force transducer in small time increments (high time resolution), wherein the processing unit corrects the high-resolution weighing signal of the first testing unit by the hysteresis error on the basis of data made available by the second testing unit.
