ABSTRACT:
An installation for non-destructive control for a metal tube in which an ultrasound sensor includes transducer elements that can be excited each at selected times. A downstream circuit for processing the sensed signals analyzes a global response of the tube at ultrasonic excitation. The transducer elements are only excited to produce a single emission and the downstream circuit recovers the samples of the sensed signals each through a transducer element, to associate therewith successive times respectively offset, to calculate plural global responses of the tube at a single emission, by modifying the shifts between the successive times.
