The invention relates to a device (68) and a method for the non-destructive testing of planar objects (70) such as thick or thin metal sheets using ultrasound in different focal zones, said device comprising one or more independently controllable probes (PK1-PKn), and to the use of matrix phased array probes. To achieve uniform sensitivity over a wide thickness range, the probes (PK1-PKn) are designed as 2-dimensional phased array probes (PK2-PKn) and are located in rows offset in relation to one another. The sum of the number and length of the individual probes (PK1, PKn) corresponds to the width of the material to be tested.
L'invention concerne un dispositif (68) et un procédé de contrôle non destructif d'objets plans (70), tels que des tôles minces ou épaisses, par ultrasons dans différentes zones focales, ledit dispositif comportant un ou plusieurs capteurs (PK1 - PKn) à commande séparée, ainsi que l'utilisation de capteurs multi-éléments matriciels. Le but de l'invention est d'obtenir une sensibilité uniforme sur une grande plage d'épaisseurs lors du contrôle. A cet effet, les capteurs (PK1 - PKn) sont réalisés sous la forme de capteurs multi-éléments 2D (PK2 - PKn) et placés en rangées décalées, la somme du nombre et de la longueur des capteurs (PK1, PKn) correspondant à une largeur du matériau à contrôler.
