PBS-4100+ Gen4 sets the standard in jet engine turbine vibration analysis and balancing
If you have worked with earlier models of the PBS family, you will recognize the same familiar, expert functions and workflow for jet engine vibration diagnostics, surveys, balancing, and maintaining historical engine data. The 4th generation unit is completely compatible with earlier PBS systems.
With traditional methods, it can take multiple time and fuel consuming engine runs to determine an approximate balance solution. Other “automated” balancing systems require you to manually enter readings or to guess which specific balance weights to use. The PBS-4100+ system is the only system that automatically collects and stores vibration data for future reference, calculates precise balance solutions, and determines the specific balance weights and balance weight locations – sometimes in as little as a “single shot” using the built-in influence coefficient method. Fuel
and time savings over conventional balance methods can be up to 80%!
The associated WinPBS software provides intuitive and easy-to-interpret balancing solution diagrams that directly indicate to the user what balance weights are required, and where they are required.
Balance solutions developed by the PBS system can be more accurate than can be consistently obtained using traditional methods. In fact, the balance solutions developed by the PBS-4100+ improve its ability to develop future balance results. Influence coefficients developed from each run are successively integrated into future balances to obtain the most accurate solution possible in the least amount of time.

What the PBS-4100+ Does
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 balance
solutions. 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.
