Use of Motion Amplified Video to Diagnose Pump Vibration
Use of Operating Deflection Shapes (ODS) has become an accepted method for understanding and diagnosing pump and other turbomachinery vibration problems. However, data acquisition can take a long period of time, and requires a large number of expensive probes, with associated FFT analyzer channels. New video magnification techniques can supplement or replace ODS.
