Abrégé
Systems and methods for monitoring the condition of ultrasonic transducers and ultrasonic probes used in non-destructive testing are provided. In one aspect, a degree of deterioration and end of life of an ultrasonic transducer can be estimated based upon measured environmental and/or operating parameters of the ultrasonic transducer. In another aspect, testing parameters acquired by a single ultrasonic probe or different ultrasonic probes can be measured and analyzed to identify deterioration of an ultrasonic probe.

Abrégé
A method for detecting geometrical imaging properties of a flat panel detector (12) in an X-ray testing system comprises the steps of: disposing a calibrating body (13) between an X-ray beam source (11) and the flat panel detector (12), the calibrating body (13) comprising at least one discrete geometrical object (30); recording at least one X-ray image of the calibrating body (13) with the flat panel detector (12), with at least one discrete geometrical figure (32) being generated in the X-ray image by imaging the at least one discrete geometrical object (30) of the calibrating body (13); and determining the positionally dependent distortion error of the flat panel detector (12) from the at least one X-ray image based on at least one feature of the at least one discrete geometrical figure (32). All features of the at least one discrete geometrical figure (32) used for determining the positionally dependent distortion error are independent from the dimensions of the calibrating body (13).

Prause, Reinhard
Breidenbach, Christof
Abrégé
The invention relates to an ultrasonic test method having an ultrasonic test step, wherein a test item is checked non-destructively by means of ultrasound generated by an ultrasonic test head, wherein a liquid coupling medium continuously circulates outside of the test head. Part of the coupling medium is diverted and fed into a coupling chamber between the ultrasonic test head and the test item. The coupling agent circuit also comprises a degassing device. Gas bubbles in the coupling agents are removed from the coupling agent by means of a settling tank and a zigzag conduit.

Koch, Roman
De Odorico, Walter
Abrégé
A device and a method for ultrasonic testing by means of a local immersion technique of a stringer component section of a flat component are provided. The device includes a test head assembly mounted as moving floatingly by a holding device in the Y-direction longitudinally. The test head assembly includes: a test head that can be connected to an automatically actuated handling device and that can be moved by the handling device along the stringer; a test head holder; and a counter-holder coupled with the test head holder by an actuation element, wherein the actuation element is configured to steer the test head holder and the counter-holder from a closed position to an open position, the test head holder and the counter-holder being mounted floatingly along a guiding rail running in the X-direction transversely to the stringer, and fit, in a force-loaded manner, to each side surface of the stringer.

Abrégé
A planar probe for the coupling of ultrasonic signals to a planar component to be tested by means of water-free jet technology is provided. The planar probe includes: at least one preflow chamber; a flow chamber located downstream of at least one preflow chamber, wherein the flow chamber extends through a slot-shaped water outlet opening to a lower surface of the planar probe; a probe, wherein a lateral surface of the probe comprises emitting/receiving elements and forms an inner wall section of the flow chamber; a base body for the reception of the probe; and a sliding plate comprising the slot- shaped water outlet opening, whose planar extension along the component is larger than the planar extension of the base body along the component, wherein the planar probe is connected to the sliding plate.
