Abstract:
The invention relates to a nondestructive testing device for detecting possible thickness anomalies (Ve) of a wall (P), this device comprising a sensor (1) including means (11) for emitting and receiving ultrasonic waves, and acoustic coupling means (2). The sensor according to the invention comprises a rigid enclosure (12, 13) sealingly defining a free internal volume (10), and the coupling means (2) comprise a solid coupling body (21) belonging to the enclosure, and a coupling liquid (L) disposed in the free internal volume (10) and in which the emitting and receiving means (11) soak.
