Eddy Current Sensor for Measurement of Cable Eccentricity

摘要

The calculation of the magnetic field distribution and the eddy current distribution was carried out with the sensor at different positions. The curves of inductance and the eddy current loss of the sensor with different internal diameter versus the cable eccentricity in Y direction were computed. The physical analysis of electromagnetic interactions between an inductive sensor and a long cable can be done for other sensor shapes and targets in the same way.
