    Abstract

    This paper demonstrates the feasibility of using solid-state magneto-inductive probes for detecting and imaging of steel reinforcing bars embedded within pre-stressed and reinforced concrete. Changes in the inductance of the sensor material are directly proportional to the strength of the measured magnetic field parallel to the sensor. Experimental results obtained by scanning steel bars specimens are presented. General performance characteristics and sensor output limitations are investigated by using different orientations, sensing distance, excitation intensity, bar sizes and geometries.
