Abstract
A rotational rheometer utilizes a rotor coupled to a test specimen and suspended in a stator by a low friction bearing suspension system, a compensation arrangement which compensates for bearing torque on the rotor throughout the full range of rotation of the rotor, and position transducers arranged for determining accurately both the angular position of the rotor throughout a full range of 360.degree. of rotation, and the longitudinal position of the rotor, relative to the stator.
