ULTRASOUND SENSOR FOR NON-DESTRUCTIVE CONTROL OF METALLURGICAL PRODUCTS |
摘要 |
The invention concerns an installation for non-destructive control for metal tube (T) wherein an ultrasound sensor (3) comprises transducer elements (Ci) which can be excited each at selected times. A downstream circuit (2, 4, 5) for processing the sensed signals analyzes a global response (7) of the tube at ultrasonic excitation. The invention is characterized in that the transducer elements are only excited to produce a single emission and the downstream circuit recovers (4) the samples (Sij) of the sensed signals each through a transducer element (Ci), to associate therewith (5) successive times (tj) respectively offset, so as to calculate several global responses of the tube at a single emission, by modifying the shifts between said successive times.
