Welcome to Vibrant NDT
Process Compensated Resonance Testing

PCRT is an advanced Non-Destructive Testing technique. 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.
