ABSTRACT
A smart EME sensor for stress monitoring of steel cables was recently proposed by the authors for the first time (Duan et al. 2011, 2012, Zhang et al. 2014). The ME sensing unit, an innovation part of the EME sensor, which is made of ME laminated composites, displays great potential to be used to design the novel magnetic detector with significant advantages such as small size, large magnetic conversion coefficient, fast response, high magnetic-sensitivity, and low cost. To calibrate and verify the EME sensor as a NDT tool to monitor the cable stress/force, this paper presents the full-scale experiment, factory calibration, in-situ verification and on-line long-term monitoring in the Second Jiaojiang Bridge of China.
