Abstract

In order to increase the crack monitoring sensitivity of a rosette eddy current array sensor, a crack-monitoring system was established, and an equivalent sensor model was developed by COMSOL. Then the influence of the sensor's topology on its sensitivity was investigated. The results indicate that the sense's sensitivity would reach the maximum when put the exciting and sensing windings in same plane. Increasing the horizontal space between exciting and sensing winding(DH) will enhance the sensor's sensitivity but reduce the sensor's output voltage. When increase the layer of winding, the output voltage will increase sharply and the sensor's sensitivity would decrease gradually. As the higher output voltage would facilitate the crack monitoring, there is a tradeoff between the sensor's output voltage and crack monitoring sensitivity in engineering application.
