A device for the destruction-free testing of components, in particular of concrete components with ultrasound is suggested, which comprises at least one sensor module with several ultrasonic testing heads functioning as transmitters and/or receivers. The sensor module is provided with a device for producing transmitter impulses for the ultrasonic radiation and with a device for acquiring the readings. Several sensor modules for forming an array are mechanically connected to one another. Furthermore, a control- and evaluation device for activating the sensor modules with their ultrasonic heads and for evaluation of the readings delivered by the sensor modules is provided, which via a bus system is connected with control- and data leads to the sensor modules.

Device for the destruction-free testing of components

Described is a method for operating a positioning vehicle for positioning a test probe in defined intervals along a travel line, as well as to a positioning vehicle for carrying out the method. The positioning vehicle contains a traveling vehicle base part with a guide device and with a test probe carrier guided by this guide device in a guide. The guiding has a first reversal point and a second reversal point. The guide device comprises guide means in order on displacing the vehicle base part to guide the test probe carrier in the travel direction up to the first reversal point after it has reached the second reversal point, and in order to lead back the test probe carrier opposite to the travel direction up to the second reversal point after it has reached the first reversal point. In the phase of the return, the test probe carrier relative to the vehicle base part has the negative speed of the vehicle base part. Described is also a device which permits in particular objects having large surfaces to be scanned with little effort.
