Zusammenfassung:	A crack detecting system operable to detect cracks along a conduit or structure includes a tool movable along a conduit or structure and having at least one sensing device for sensing cracks in a wall of the conduit or structure, and a processor operable to process an output of the at least one sensing device. Responsive to processing of the output by the processor, the processor is operable to determine cracks at the wall of the conduit or structure. The at least one sensing device employs excitation in the form of a high current continuous or pulse wave that is applied to a magneto-mechanical impedance transducer/sensor coil to generate a mechanical wave in the conduit or structure.
