    摘要: Barcode patterns or other meaningful patterns are printed with a differentially conductive ink. A sensor incorporating a plurality of capacitive couplings distinguishes features of the patterns by comparative measurements that are largely independent of variations between the sensor and the patterns affecting all of the couplings. The patterns can be distinguished despite being hidden from view, such as inside sealed envelopes.

    摘要: A torque transmitter comprising two members 1, 2 rotatable relative to each other and serving to transmit a torque, and which has the ability to continuously measure the transmitted torque. The transmitter includes a transducer ring 3, and a displacement measuring device 6 having at least two noncontacting sensors 4, 5 for detecting the axial position of the transducer ring 3 relative to a reference member 7. The members 1, 2 are inter-connected via transverse beams and connected with the transducer ring 3 via fork-like members, so that upon a torque being transmitted between the members 1, 2, the latter are rotated relative to one another proportionally to the torque, and the transducer ring 3 is axially displaced. To achieve an error-free and reproducible determination of the torque, the transducer ring 3 and the reference member 7 are provided with surfaces 8, 9 which are substantially parallel to each other and axially aligned with each other, and the sensors 4, 5 occupy a fixed position and are arranged such that they measure against the surfaces 8, 9 either in a direction opposite to each other or toward each other.

    摘要: A method of error compensation for transducers having non-linear characteristics is shown. A computer-supported measuring circuit is used. In a first factory alignment, the output characteristic of the transducer is set so that it can be linearized by the computer using a power function. The appropriate exponent of the power function is stored. At the place of use, at least three calibration measurements are performed with the installed transducer using defined calibration measured values substantially spanning the measuring range of the transducer equidistantly. The power function is solved with the calibration measuring results and the stored exponent, so that the constants not yet known can be calculated. During every following service measurement, the actual measuring result is put into the now solved power function. The result of the equation is then outputted as the error-compensated measuring result.

    摘要: The invention relates to a contactlessly working eddy current sensor, particularly for detecting essentially flat test objects, comprising at least one sensor coil, eddy currents being able to be induced in the test object. The invention is characterized in that the coil, when passing by the test object, is aligned in such a manner that the coil axis is oriented essentially parallel to a line normal to a surface to the test object, and that the test object can be moved past the sensor coil essentially parallel to the coil axis or the sensor coil can be moved past the test object. A corresponding method is carried out so that an eddy current can occur only once when the test object or coil is passed by.
