Publication number: 20210278375Abstract: A method and a device for testing a component by means of ultrasound is described. It is based on using transducers (4) for sending a probe signal into the component and monitoring its propagation. The response signals (C1 . . . C7) of the individual receivers are analyzed for the strength (A) of the arriving surface wave, and this strength (A) is used for scaling the response signals (C1 . . . C7). This allows to compensate for variations in the coupling strength between the various ultrasonic transducers {4}.Type: ApplicationFiled: October 19, 2016Publication date: September 9, 2021Applicant: PROCEQ SAInventors: Felix GATTIKER, Thomas SCHLEGEL, Ralph MENNICKE

Publication number: 20100307258Abstract: An apparatus and a method are described that determine the compressive strength of a solid by rebound. The method and apparatus have a reduced sensitivity to error sources, i.e. gravity, internal friction and operator interference (unsteady holding of the instrument). The improvements are achieved by contactless measuring of the quotient of rebound to inbound velocity recorded immediately before and after the impact. Matching the mass of the mallet (3) to the plunger (5) yields higher efficiency, less angular variation of the impact energy and lighter weight. Added benefits of the invention are: Extended range of measurement and simplified mechanical adjustments, calibration and maintenance.Type: ApplicationFiled: September 20, 2007Publication date: December 9, 2010Applicant: Proceq SAInventor: Marco Brandestini
