Eddy current monitoring system.

Such equipment ranges from from small machinery to large critical machinery. A proximity system consists of an eddy current probe extension cable and driver. Eddy currents are the root cause of the skin effect in conductors carrying ac current. Proximity sensors work on the eddy current principle.

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. The stainless steel probe sleeve is tailored to the exact insertion depth required and the probe can be exchanged without recalibration. For the greatest protection from harsh industrial conditions the heavy duty mtn ephd80 eddy current probe system has a rugged ip65 cast aluminium driver housing with integral probe. It is used for measuring shaft vibration axial position rotational speed and phase in rotating equipment.
