Abstract

A process and apparatus for measuring rheological properties of semi-solid bodies. The apparatus comprises a vessel (4) containing the body (5 ) to be tested, a measuring head (3) immersed in the vessel (4) in the middle of the body, and a drive for driving the head (3) in rotation through the intermediacy of an axle. The driver imparts a sinusoidal or pseudo-sinusoidal rotational motion to the axle (2), a torque sensor (7) and an angle sensor (8) which are mounted on the axle (2) and are both connected to a processing device for processing information, such as a device for processing signals (9) connected to a microcomputer (10).
