由于巨大仪器惯性原因能够破坏通过旋转流变仪得出的震荡测试,这与电机轴的周期性加速和减速造成的。在一台流变仪上,电机的扭矩输出是由所需克服仪器惯性的扭矩组成的且扭矩变形进行示例。扭矩惯性的增加与所施加的功率频率相关,通常在低粘度测试的样品中起到主导地位。配备独立传感器的旋转流变仪受惯性影响要小得多,主要因为样品扭矩是由电机扭矩单独决定的。
Results from oscillation tests performed with rotational rheometer can be corrupted due to huge instrument inertia contributions, related to the periodic acceleration and deceleration of the motor shaft. In a rheometer the torque output of the motor is composed of the torque required to overcome the instrument inertia and the torque deforming the sample. The torque contributions for inertia increase with the applied frequency to the power two and usually dominate the instrument response for low viscosity test samples. Rotational rheometers with a separate transducer are much less susceptible to inertia effects, since the sample torque is determined independently from the motor torque.
