The MFS-RDS provides you with a basic setup for performing rotor dynamics experiments and learning vibration signatures of different machine malfunctions. However, a detailed investigation of a particular phenomenon will require additional attachments and fixtures. SpectraQuest has designed option kits for performing different in-depth studies on the MFS-RDS.
