PCT No. PCT/SE97/01159 Sec. 371 Date Feb. 25, 1998 Sec. 102(e) Date Feb. 25, 1998 PCT Filed Jun. 26, 1997 PCT Pub. No. WO97/49981 PCT Pub. Date Dec. 31, 1997A method for determining the rheological properties of a sample substance by the use of a rheometer, in which at least one element having magnetoelastic characteristics is received in said sample substance. The element is set into mechanical oscillation by the influence of a magnetic field and its oscillation characteristics are determined by the effect exerted by the oscillation of the element on an outer magnetic field which, in turn, provides information regarding the rheological properties of the sample substance. The device comprises a receptacle for the sample substance and the element. An exciting coil array is provided for exciting the element, thus causing it to oscillate mechanically; and a sensing coil array is provided to register the effect of the element on an existing magnetic field image during oscillation of the element. A calculation unit is operatively engaged with the sensing coil array for determining the oscillation characteristics of the element and therefrom deriving the rheological properties of the sample substance. |
