ME - Machinery Analysis / CM


Assessing the health of rotating equipment allows reliability and integrity strategies to be realised. Depending on the criticality of the equipment, rotating equipment can be measured on a routine basis or continuously with an on-line system.

Vibration measurement parameters must be set appropriately to obtain the necessary data to detect machinery faults during the early stages of equipment deterioration. Inspection and remediation strategies can then be developed and implemented to mitigate the risk of unplanned maintenance and downtime.


TDC offer the full range of Vibration Analysis services as a predictive maintenance method which allows early detection of rotating machinery failure.


We use the most technologically advanced SPM Condmaster software and data collectors to capture vibration readings from plant and machinery. This facilitates the identification of the root cause of the problem so corrective measures can be implemented to improve the performance, integrity, reliability and availability of rotating equipment, therefore reducing potential downtime.
