ULTRASONIC MEASURING ASSEMBLY AND METHOD FOR DETECTING THE WALL THICKNESS OF A PIPE

摘要

The invention relates to a measuring assembly (1) for detecting the wall thickness of a pipe (47), comprising an ultrasonic probe (3) and a testing head (2) with a main element (5) which receives an ultrasonic probe (3) and the lower face (7) of which defines a main element support surface (17). The testing head (2) has two wing elements (23, 24), the lower face (31) of each of which defines a wing element support surface (32) and which are held on the main element (5) in a pivotal manner about pivot axes (A₁, A₂) extending substantially parallel to one another in a longitudinal direction (L) such that the wing element support surfaces (32) can be moved towards each other and away from each other. The wing elements (23, 24) are connected via synchronizing means (30) such that the pivotal movements of the wing elements about the corresponding pivot axes (A₁, A₂) are carried out in a synchronous manner. The invention also relates to a method for detecting the wall thickness of a pipe (47) using the measuring assembly.
