摘要

A differential excitation coil eddy current sensor based on a rectangular geometry is proposed and designed. The working principle of this sensor is analysed based on mathematical theory and the principle of electromagnetic induction. Analysis shows that, owing to the superposition effect, this sensor can induce higher magnetic flux density so that it can detect a stronger disturbance when it encounters defects in the conductor. The high sensitivity of the sensor is verified through experiments.
