Special Online Vibration Application – Determination of lengths variation of stretch on chains

Sven Fleischer, Area Sales Manager , PRUFTECHNIK S.E.A. Pte. Ltd


Online, permanent vibration system to monitor machine and bearing vibration for early symptom recognition and root cause analysis. The application includes a special part, the determination of lengths variation of stretch (chains or similar). Therefore, the tension carriage movement indicates step chain stretch directly as a long-time based process. An uneven tension carriage movement will be recognized by measure the movement with magnet-restrictive displacement sensors. This is done by postprocessing of the synchronous time plots of the two sensors
