摘要： The present invention relates to a load cell for a scale having a monolithically configured measurement body that has a force reception section, a force introduction section, and a joint section arranged between the force reception section and the force introduction section, having at least one strain gauge arranged at the upper side on the joint section for detecting a stretching deformation of the measurement body, and having electronics that are arranged at the force reception side, that are at least partly arranged on a circuit board, and that have a memory in which calibration data of the load cell and/or a value for gravity are stored, wherein a hardware interface is provided via which the memory can be accessed and via which the calibration data stored in the memory and/or the value for gravity can be changed.

摘要： A fixture includes a shelf upon which items may be placed. In one implementation, the shelf is supported by four load cells that provide load cell data that may be used to calculate weight data for the load on the shelf. The load cells are mounted underneath a frame, with an upper portion of a load mount extending upward through the frame and engaged to the shelf. The shelf and the frame include stiffeners to increase rigidity, improving the quality of the load cell data. Electronics and a wiring harness are located underneath the frame. In this configuration, assembly of the fixture may be accomplished completely from the underside, simplifying assembly.

摘要： A digital filter for a digital weigher reduces a calculation time in an adapted filter while maintaining weighing accuracy, a digital weigher includes the filter for the weigher, and a wave filtering process method uses the digital filter for the digital weigher. A fixation section of a FIR filter removes an oscillating component in a predetermined frequency range, from a digital weighing signal. A determination device determines whether an amplitude of an oscillating component contained in a digital weighing signal derived by performing a wave filtering process falls within a predetermined damping range. A control device changes a frequency range of an oscillating component to be removed by an adaptive section of the filter based on a result of the determination. The adaptive section of the filter performs the wave filtering process with respect to the oscillating component in the frequency range changed by the control device.

摘要： A device and a method for evaluating signals from load cells with strain gauges (SG), which require electronic signal evaluation with very low offset voltages due to the small output signal. In order to be able to use inexpensive components as well, two different operating points of the SG are set in two consecutive measurements, each being determined by a single voltage reference. The voltage in the zero branch of the bridge circuit of the SG is amplified in a differential amplifier and digitized with an ADC. In this context, the reference for the ADC is derived from the operating point of the SG that is determined by the respective voltage reference. The digitized offset and the initial value of the load cell are calculated from the two measurement values in an arithmetic logic unit.
