Abstract
An absolute thickness distribution cannot be accurately calculated with a conventional technique. A sensor device is provided that includes a plurality of magnetic sensors arranged to face an outer circumference surface of a pipeline and ultrasonic sensors arranged to face the outer circumference surface and measure a thickness of the pipeline in a measurement region in which the plurality of magnetic sensors measure a magnetic field, the ultrasonic sensors being less than the plurality of magnetic sensors.
