    • Device and method of on-board weighing of harvested materials on a harvesting machine having a path for the harvested material. The device includes first and second weighing devices disposed near each other on a common support and being connected to an electronic computer. The first and second weighing devices are one of an electronic balance or scale. The second weighing device is equipped with a weighing platform which is installed in the path of the harvested material. A feed system is included which is independent of the weighing platform The method includes supporting a known fixed mass on the first weighing device, successively weighing the known fixed mass on the first weighing device, feeding, with the feeding system, the harvested material continuously and in successive lots onto the weighing platform of the second weighing device, weighing the harvested material on the second weighing device, and processing signals from the first and second weighing devices using the computer. The computer performs algorithmic processing of the signals to eliminate a dynamic interference effect which results from one of slopes, tilts and vibrations of the harvesting machine.

    • 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.

    • The invention relates to a disc-shaped transducer (10) for a weighing system, comprising surfaces (14) which extend parallel to one another and in a direction of application of a force (F) to be measured, at least one of said surfaces being provided with a sensing element (13) for converting a force-dependent deformation into a useful signal. Transducers (10) of this kind usually exhibit a material-dependent, significant hysteresis effect which adversely affects their calibration possibilities; therefore, the transducer (10) comprises four sub-faces (21) which are formed by a centre line (17) parallel to the direction of application of the force (F) and a centre line (20) which is orthogonal thereto, at least two of said sub-faces which adjoin one another in only one point comprising a respective area of reduced cross-section or reduced thickness, so that the hysteresis can be compensated for.

    • Load shift compensation of a strain gage load cell is accomplished by connecting a pair of fixed resistors in series across the output of a bridge circuit incorporating the load cell strain gages. The junction point between the series resistors is established at a desired signal level by a digital to analog converter connected thereto or by a voltage divider network so that, in effect, a part of the resistance of the resistors required to achieve load shift compensation is made to shunt a pair of the strain gages in the bridge circuit. The required signal level may be established by positioning weights on the scale platter at different positions parallel to the longitudinal axis of the load cell beam and adjusting the signal level at the junction point between the shunting resistors until a desired degree of compensation is achieved. The digital correction value required at the input of the digital to analog converter to achieve compensation is stored in the memory of the scale computer.

    • A weighing system including a weighing cell (1) which supplies a measurement signal (I) to an A/D converter (3) via a signal line (2). An interference signal (i), superposed on the measurement signal, is decoupled out of signal line (2) at the signal output of the weighing cell (1), rotated by means of an inverter (4) in terms of phase by 180.degree., and again coupled into the signal line (2) at the signal input of the A/D converter. An ohmic resistance (RO) is connected in series in the signal line (2) between the uncoupling node (AK) and the in-coupling node (EK). The interference signal (i) is decoupled preferably capacitively via a series circuit that forms the frequency-determining member of the active low-pass filter including a condenser (C) and an ohmic resistance (R1). On the other hand, a galvanic coupling (R3) is provided for the recoupling of the interference signal (-i). With this active low-pass filter, one can attain a substantially complete suppression of the interference signals without any subsequent adjustment of the filter.
