A rotary rheometer has a stator arranged in a rotationally invariant fashion, and a rotor that can be rotated about the axis of the stator by an eddy current drive. Wherein the test medium to be examined can be introduced into at least one measuring gap formed between surfaces of the rotor and the stator located opposite of one another. Accordingly, the measuring gap filled with the test medium to be examined functions as and/or is configured as a hydrodynamic bearing between the rotor and the stator. The distance and mutual position of the mutually facing surfaces of the rotor and the stator defining the measuring gap are predetermined and set, and are maintained during the measuring process, exclusively by the hydrodynamic bearing action generated by the rotation of the rotor relative to the stator. |
