摘要： An exemplary mounting arrangement serves for the mounting of a force transducer that has a sensor-equipped core part connecting a support part to a force-application part. The support part can be bolted to a fastening part by mounting screws, and the force-application part can be bolted to a weighing pan carrier by means of mounting screws. The support part and the force-application part of the force transducer can each have a triplet of threaded holes serving to receive the mounting screws. Each triplet forms an isosceles triangle whose apex points towards the deformable body. The symmetry axes of the triangles lie in a plane that is parallel to the displacement travel of the force transducer. The mounting arrangement can be further configured to provide an effective overload protection in a low-profile design and to provide a thermally uncoupled fixation.

摘要： A force sensing module with reduced sensitivity to torque in order to accurately measure weight in the presence of longitudinal and lateral torques, comprising two or more sensing means mounted vertically with output signal means combined and adjustable to minimize longitudinal torque response. The force sensing module further comprises a vertical support for lifting and supporting a load, a support arm coupled to the vertical support for engaging and holding a load, first and second sets of strain gauges, spaced from each other and either in vertical or horizontal alignment with each other. The strain gauges are connected at one end to the vertical support and at the other end to the arm for receiving a force proportional to the load and for receiving a torque from the arm. The force sensing module also comprises first and second Wheatstone bridges, wherein each Wheatstone bridge comprises one of the sets of strain gauges and at least one variable resistance coupled between the Wheatstone bridges with a resistors adjustable to reduce the sensitivity of the Wheatstone bridges to torque applied to the sets of strain gauges through the support arm. The force sensing modules are useful in the measurement of medical patient weights where great accuracy is required for diagnostic and treatment needs.

摘要： An electronic weighing sensor (10) having a digital signal processing unit (19), which includes at least one filter (12) with low-pass characteristic. By means of the filter (12), the direct-current component (m) is determined from the output signal of the weighing sensor and the weighing result is derived therefrom. A signal, which is dependent on the amplitude of the vibrations, is determined by the digital signal processing unit (19) and electronic components (18) change the direct-current component (m) as a function of the magnitude of the vibration-dependent signal. This significantly improves the performance of the weighing sensor (10) with respect to shocks and vibrations in the installation site of the weighing sensor (10).

摘要： A weighing apparatus has a scale cell and a dummy cell, both similarly structured and cantilevered. A load to be measured is applied to the free end of the scale cell and a standard weight is attached to the free end of the dummy cell. Analog electrical signals from these cells are converted to digital data. The effect of the standard weight is removed from the digital data from the dummy cell to obtain the effect of external vibrations which effect is multiplied by a suitable coefficient dependent on the applied load and subtracted from the digital data from the scale cell.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A weighing apparatus employing dual load cells or dual load cell sets is provided with a hinged weigh frame attachment to transmit only vertical load to one load cell or set of load cells and prevent transmission of moments about the longitudinal axis. A ball and dual cup arrangement is connected between the weigh frame and the other load cell or set of load cells to transmit vertical load but prevent the transmission of moments about either the longitudinal or transverse axes of the load cell. Because of the decoupling arrangements, the weighing apparatus requires only longitudinal shift adjustment for only the load cell(s) connected to the hinge.
