Abstract
The invention relates to an ultrasonic NDT sensor arrangement for inspecting surfaces of variable geometry of metal bodies. The sensor arrangement includes a housing with a hollow inner space and an opening, through which part of an incoming sound beam exits the housing to enter a metal body to be tested. An ultrasonic sensor is coupled to the housing such that it emits said incoming sound beam directly into said hollow inner space in a direction towards the opening. The said inner space of the housing is filled with a first coupling fluid which is water. The opening of the housing is closed with a closing member, which is made of a silicone material and which has a similar density and velocity of sound compared to the first coupling fluid.
