Pulser for Piezoelectrics Transducers Used in Non-destructive Testing
In order to get, at the ultrasonic receiver input, a clear echo pulse, it is very important to apply on the transducer a short high amplitude pulse (hundreds of volts). The pulse frequency is low enough to allow the reception and processing of the informations received from the analysed material between two adjacent pulses, but high enough to ensure an integral control of the material. The piez...
متن کاملNon destructive testing of electronic devices by acoustic microscopy
2014 The interest of the scanning acoustic microscope previously demonstrated in the biomedical field is extended to microelectronic applications. The properties of penetrating and focusing of acoustic waves in solids are particularly suitable for non destructive observation of surface and subsurface of solid state structure and device such as integrated circuit, epitaxial, implanted and diffus...
متن کاملPipe Robots for Internal Inspection, Non-Destructive Testing and Machining of Pipelines
Inspector Systems is a specialist in manufacturing of tethered self-propelled pipe robots for internal inspection, non-destructive testing and machining of pipeline systems. Our industrial sectors, which originates from 30 year experience in the nuclear industry, are Gas & Oil (On-/Offshore, Refineries), Chemical, Petrochemical, Water etc. The pipe robots are able to get inserted through poor a...
متن کاملElectromagnetic Acoustic Transducers for Robotic Nondestructive Inspection in Harsh Environments
Elevated temperature, gamma radiation, and geometric constraints inside dry storage casks for spent nuclear fuel represent a harsh environment for nondestructive inspection of the cask and require that the inspection be conducted with a robotic system. Electromagnetic acoustic transducers (EMATs) using non-contact ultrasonic transduction based on the Lorentz force to excite/receive ultrasonic w...
متن کاملNon-Destructive Testing
This book consists of a collection of 27 articles dealing with the subject of probabilistic engineering mechanics with special emphasis on the ensuing computational issues. The book has two parts. The first part is meant as a tutorial on the basic aspects of probabilistic mechanics, whereas the second part is an overview of some of the applications that rely on probabilistic concepts for their ...
