1. An Otech 600 series system using eZ Balance provides a solution for multi plane field balance applications of rotating machinery eZ Balance computes the optimal balance weights and their locations based on vibration data collected from the analyzer The data is displayed in a convenient Polar plot that indicates the magnitude and phase of the unbalance as well as time and spectrum data eZ Balance determines a balance solution by calculating the change in vibration condition based on adding trial weights The balance process is a series of well defined steps Accelerometers velocity probes or displacement probes may be used to measure the vibration level at each balance plane A tachometer measures the rotation speed and provides a phase reference Features e Single Multi plane and trim balancing e Polar time and spectral displays e Computes and stores influence coefficients for future trim balancing e Vibration data can be acquired from the analyzer or entered manually e Balancing toolkit Trial weight calculations Weight splitting Centrifugal force Stock weights Weight removed Unbalance tolerance e Balance solution can be based on multiple response points 5 4 Software Options 928291 652u and 655u User s Manual eZ N D T Does not support 652u or 655u Non Destructive Test Software eZ NDT non destructive test uses resonance to identify part variations caused by process inco2.
