Applications

Vibration Surveys

Quickly assess the current condition of your jet engine by using the WinPBS vibration survey functionality. A variety of intuitive and informative display formats provide PBS users a wealth of information that can be viewed in real time, or after the fact in the system Data Viewer.

“One-Shot” Trim Balancing

Gone are the days of multiple engine runs, polar graphs, and handwritten solutions! The PBS can quickly characterize the rotors in your engine, allowing for highly accurate single run balancesolutions. Automated reports are generated providing users a clear picture of how well balanced the engine is.

Trim Balancing using Trial Weights

Fine tune your PBS’ characterization of the engine using trial weight balances to develop “influence coefficients” that can be utilized for quicker future balances.

Vibration Diagnostics

The PBS-4100+ system has tools specifically designed to help you quickly identify the sources of vibrations and take the appropriate corrective action before a potential catastrophic failure.

Spectral Analysis

Pinpoint the exact sources of vibrations and solve tough diagnostics problems with the integrated spectral analysis of the PBS system.

Tachometer Signal Conditioning

With its unique tachometer signal conditioning circuitry, the PBS 4100+ can accept speed signals from all jet engine types and tachometer generators. Phasing (1/REV) information can be derived from all types of odd-tooth signals, including long, short, and offset (phase) tooth embedded signals. An external 1/REV output for outside equipment is provided.
