Using Giant Magneto-Resistance Sensors in Remote Field Eddy Current Tube Inspection

A. Lopes Ribeiro, H. M. Geirinhas Ramos, Dário Pasadas, Tiago Rocha
  • Abstract:
    This paper presents a remote field eddy current probe that includes a giant magneto-resistance (GMR) as magnetic sensor in order to detect longitudinal and circumferential defects in stainless steel tubes. The high sensibility of the GMR sensor in a large frequency range (0 Hz – 1 MHz) allows us to consider that it can be a good candidate to analyze several defects in tubing by a remote field testing method. Experimental data were acquired by a measurement system to verify the sensibility of the GMR in defect detection and to create a new probe. In this work, simulations were also made in order to verify the veracity of the obtained experimental results.
