The RMS turntable system SDK431/7 is used for testing specimens by applying defined rotational movements. Gyroscopic systems, acceleration, or rotational speed sensors can be measured using the turntable as a highly accurate reference. The turntable system is integrated into a robust aluminum case. Also integrated into the case, alongside the drive unit, is the “RMS Motion Controller SDC” control system. This is a control system consisting of the operating software SDC CONTROL in combination with a self-sufficient signal processor.
