Eddy current monitoring system. Such equipment ranges from from small machinery to large critical machinery. 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. The cmss 785 system is an eddy current type non contact displacement vibration system.
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. It is used for measuring shaft vibration axial position rotational speed and phase in rotating equipment. Proximity sensors work on the eddy current principle.
