    • A system and method is provided for determining the torque and kinetic energy of a rotating body without contacting the rotating body. Graduation markings are applied to mark regular angular displacements on the object. Reflected laser light from the graduations is sensed and converted into a pulsed signal. The pulses of the signal are time stamped and used to determine the velocity of the rotating object at angular displacements which can be less than 360 degrees. Changes in angular velocity during each rotation can be measured and used to determine changes in torque and kinetic energy during each rotation.

    • A torsion sensor (1) using an optical waveguide (2) in optical communication with a diffraction grating (3), preferably a tilted grating, and most preferably a tilted Bragg grating, which provides the optical waveguide and grating with a torsion-dependent collective optical transmission spectrum. Changes in the collective optical transmission spectrum of the waveguide and grating, induced by changes in the amount of torsion applied to the waveguide, may be detected (12) by detecting a corresponding change in the intensity of optical radiation transmitted through the grating from a controlled optical source (5). The degree of change in the collective optical transmission spectrum is dependent upon the degree of torsion (twist) applied to the optical waveguide. Measuring the magnitude and/or sense (i.e. increase/decrease) in the intensity of optical radiation transmitted through the grating from an optical source enables torsion to be sensed.

    • Device for a torque or shear transmitter for determination of fibre concentration or viscosity in pulp suspensions and which is adapted to measure an angle deviation between two concentric shafts (9, 11) whereby the arisen angle deviation forms a function of the torque applied on the measuring body (5). The device comprises a feedback system for bringing the inner shaft or measuring shaft (11) to take a zero position independent of the magnitude of the torque, and which system comprises an electromagnetic feedback coil (18), which encircles two pole shoes (19) journalled in bearing points (20) at the end of the outer shaft in the form of a hollow shaft (9), at the same time as each pole shoe (19) is connected to the measuring shaft (11), whereby a current, generated by means for a transducer (12) and is dependent on the present angle deviation, is sent to the winding (23) of the coil (18), where a magnetic field of force (25) is generated, whose strength is determined by the current flowing through the coil (18) and the distance (24), which arises between the pole shoes (19) and the magnetic parts of the feedback coil, which latter obtain different polarity and provides a resetting of the pole shoes (19) together with the measuring shaft (11) to a present set point at the same time as the magnitude of the current is a measure of the present shear force torque and is convertible to a suitable output signal.

    • The invention relates to a method for determining a rotational angle ( PHI ) and/or an angle differential ( delta ) on a divided shaft (3), on which several coded phase tracks (1a, 1b, 2a, 2b) are arranged. Each group of tracks (1a, 1b and 2a, 2b) supplies a phase signal ( alpha 1, alpha 2) via an evaluation unit, each signal being equivocal with regard to a rotation of the shaft (3). The two or more phase signals ( alpha 1, alpha 2) are added together in a weighted manner to form a signal S and the integral fraction and non-integral fraction are formed therefrom. The non-integral fraction is proportional to the angle differential ( delta ) between the two groups of tracks. The torque (M) can be determined by multiplying said angle differential by the spring rate of an inserted torsion rod. The unequivocal angle of rotation ( PHI ) is determined by the weighted addition of the integral fraction of the signal (S) and a phase value ( alpha 1) or ( alpha 2).
