Abstract (en)
[origin: WO2009077107A1] The invention relates to a rotary rheometer for measuring rheological parameters of a material sample, comprising a motor, the torque thereof being detectable, said motor driving a rotary shaft, the speed and position thereof being detectable. A rotor is attached to the shaft, and a measurement space for receiving the material sample is formed between the rotor and a stator. A controller controls the motor on the basis of an internal control method and internal control parameters, wherein the internal control method and internal control parameters of the controller can be changed and adjusted. Rheological characteristic values of the material sample and/or test parameters can thereby be input into an evaluation unit, wherein the evaluation unit determines the corresponding internal control method and the internal control parameters on the basis of the input characteristic values and/or test parameters.
