    摘要: An ultrasonic flow sensor, in particular for determining the flow velocity of a medium flowing through a pipeline, has at least one ultrasonic converter for transmitting and/or receiving ultrasonic signals, an oscillator, which is connected with the ultrasonic converter, and an evaluation unit, which determines a phase shift of the ultrasonic signal that was received, with respect to a reference signal. The evaluation unit includes a plurality of quadrature demodulators, which operate with different demodulation frequencies and each determine phase information about the ultrasonic signal that was received, and when a vernier unit is provided, which determines—based on the individual pieces of phase information—a phase angle or a quantity proportional thereto.

    摘要: The invention proposes a method for determining a rotation angle or distance by evaluating a multitude of phase measurement values. By means of a linear transformation A, the phase values measured in an N-dimensional space are projected into N-1 new signals Si. These signals Si are transformed by a quantizing device into corresponding integer values Wi and converted into N real values Zi by means of a linear projection C. These values have weighted phase measurement values &agr;i added to them in modulo 2&pgr; fashion, which yields N estimates for the angle &phgr; to be measured. The N estimates are corrected if needed at their skip points and are added up in a weighted fashion, taking into account their phase angle.

    摘要: The invention proposes a method for determining a rotation angle (&PHgr;) and/or an angular difference (&dgr;) in a divided shaft (3), which has a number of phase tracks (1a, 1b, 2a, and 2b) disposed on it, which are provided with codes. Via an evaluation unit, each group of tracks (1a, 1b, 2a, and 2b) supplies a phase signal (&agr;1, &agr;2), which is respectively ambiguous with regard to a rotation of the shaft (3). The at least two phase signals (&agr;1, &agr;2) are added up in a weighted fashion to produce a signal S from which the integer portion and the non-integer portion are calculated. The non-integer portion is proportional to the angular difference (&dgr;) between the two track groups. The torque (M) is determined through multiplication with the spring rate of an interposed torque rod. The unambiguous torque (&PHgr;) is determined from the integer portion of the signal (S) and a phase value (&agr;1) or (&agr;2) with the aid of a weighted addition.

    摘要: The invention relates to a method for unambiguously determining a physical parameter Φ using m phase-measured values αi with 1≦i≦m, whereby the phase-measured values αi have different, integer periodicity values ni and an integer periodicity difference (a) with Δn>1 within an unambiguous range E of the physical parameter Φ. A value T with (b) and (c) is calculated based on the phase-measured values αi and the periodicity values ni thereof, and, within a reduced unambiguous range Ered with (d), a value V is allocated to the value T by allocation according to (e), wherein TUk stands for a respective lower limit and TOk for a respective upper limit of T. The allocation intervals between the upper (TOk) and the lower limits (TUk) for T, as wells as the distances (f) correspond at least to the periodicity difference Δn. In order to determine the physical parameter Φ, value V is added up with the C phase-measured values αi in a weighted manner.
