Eddy Current Monitoring System

Such equipment ranges from from small machinery to large critical machinery.

Eddy current monitoring system.

The cmss 785 system is an eddy current type non contact displacement vibration system. A high frequency rf signal is generated by the driver sent through the extension and probe cables and radiated from the probe tip. Eddy currents are the root cause of the skin effect in conductors carrying ac current.

A proximity system consists of an eddy current probe extension cable and driver. It is used for measuring shaft vibration axial position rotational speed and phase in rotating equipment. Proximity sensors work on the eddy current principle. Iiw commission xiii wg 5 xiii wg5 104 15 eddy current crack monitoring system for structural health monitoring shm applications e.

Eddy current techniques are commonly used for the nondestructive examination nde and condition monitoring of a large variety of metallic structures including heat exchanger tubes aircraft fuselage and aircraft structural components.
