    Abstract: A method of calibrating the torque outputs of a rheometer by using a calibrating object with a certified moment of inertia, measuring the moment of inertia of the calibrating object using the rheometer, and calculating the torque adjustment factor by dividing the certified moment of inertia value by the measured moment of inertia value. The torque adjustment factor is applied to correct subsequent measurements of rheological properties conducted using the rheometer. The torque adjustment factor may be double-checked for reproducibility by measuring the moment of inertia of the calibrating object, correcting it with the torque adjustment factor, and comparing it with its certified moment of inertia value.

    Abstract: A process (50) for removing a modulation sinusoidal error from signals of a rotating load cell measuring forces and/or moments with respect to a non-rotating orthogonal coordinate system includes mounting the load cell to the rotating object and obtaining a first set of signals from the load cell, wherein at least one signal of the first set of signals is indicative of a load as the object rotates. A characterization of a modulation error is obtained from the first set of signals. The modulation error is a periodic signal having a frequency greater than and proportional to a frequency of revolution of the load cell. A second set of signals is calculated as a function of the characterization of the modulation error from the first set. The calculated modulation error in the second set of signals is substracted from the second set of signals.

    Abstract: A device (40) for the detection of mechanical forces exerted on a rail such as a railway rail (17), comprising a mechanical detection element (41), which is coupled to said rail (17), and sensor means (45). The sensor means (45) are built up of at least two sensors that are in mechanical contact with each other, which elements are each provided with terminal electrodes, wherein one element is of a first type, arranged for exerting a mechanical force under the influence of an electric signal applied to its terminal electrodes, and wherein another element is of a second type, arranged for providing an electric signal at its terminal electrodes under the influence of a mechanical force being applied thereto. The mechanical detection element (41) and the sensor means (45) are in engagement with each other, in such a manner that mechanical forces exerted on the rail (17) during use are transferred to the sensor means (45) by the detection element (41). An alternating and/or pulsating electric signal is thereby continuously applied to the connecting electrodes of an element of the first type, and the electric signal provided at the terminal electrodes of an element of the second type is a measure for the mechanical forces exerted on the rail (17). In this manner the device has a "sel-monitoring" or so-called "fail safe" operation, as is required for many rail transport systems. The sensor elements of the first and the second type are preferably of a piezoelectric material.

    Abstract: This invention is concerning a precalibrated multi-component sensor, here called a master balance, intended for determination of applied forces and moments in the calibration of multi-component sensors, here called object balance, normally used for aerodynamically tests in wind tunnels. During the calibration procedure, the object balance is connected in series with the master balance, which in turn is fastened to a frame, here called a calibration rig. Characteristic for this invention is that the master balance is fastened to the calibration rig frame by an attachment joint in a plane perpendicular to the main axis, common to master and object balances, with the attachment joint being lifted up to the same or nearly the same level as the moment center of the object balance.
