Expert Certification
Rotor Dynamics, ODS, and PdM Program Leadership
Category III is the highest CMVA vibration certification level. This program is designed for senior reliability engineers and PdM program leaders who need mastery of advanced analytical techniques including rotor dynamics, operating deflection shape (ODS), frequency response function (FRF) testing, and program strategy.
Delivered by Iraj Roy, CMVA Cat III, who actively uses every technique covered in this program on industrial machinery.
