Abstract
Provided is a sensor system which can detect a thickness reduction, a crack, or the like of a pipe or a container covered with a thick coating member through ultrasonic inspection without attachment and detachment of the coating member. A sensor system used for nondestructive inspection includes a sensor attached to a surface of an inspection target, a sensor coil that is electrically connected to the sensor via a first cable, a first electromagnetic wave blocking member that is disposed between the surface of the inspection target and the sensor coil, a sensor side coil that is disposed to face the sensor coil with a gap and is coupled to the sensor coil through electromagnetic induction, and a probe side coil that is disposed to be separated from the sensor side coil and is electrically connected to the sensor side coil via a second cable.
