Abstract: 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.
