A device, and corresponding test method, for testing metallurgical products including an ultrasonic sensor including a plurality of elementary transducers which can be operated independently of each other and are distributed in accordance with a two-dimensional pattern is described. A first electronic component is configured to excite each of the elementary transducers in accordance with at least one temporal law corresponding to a burst of ultrasonic waves in a line of sight. A second electronic component is configured to process at least a portion of the signals captured by each of the elementary transducers. Each temporal law is arranged such that the corresponding burst produces a beam of ultrasonic waves which is generally divergent about the line of sight on moving away from the ultrasonic sensor.
