Welcome to Vibrant NDT
Process Compensated Resonance Testing
PCRT is an advanced Non-Destructive Testing technology. The test components are excited with minute, through thickness vibrations generated by dry coupled piezoceramic transducers, from a continuous swept sine frequency input. The resonant spectra of the excited components will then be logged permanently in a digital library and compared to spectras from known good and defective components.
Unlike previous resonance-based techniques,the system employs software algorithms and temperature compensation to enable acceptable manufacturing variations to be accounted for,whilst rejecting small spectral variations outside the group of acceptance, which denote out-of-spec defects in components.
