PBS-4100+ Gen4 sets the standard in turbine engine 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 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 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 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.

Why choose the PBS-4100+?

Multiple Data Views

While the system is collecting data, users may view the data in several different formats. These data displays include tables, bar graphs, x-y plots, waveforms, vibration surveys, strip charts, frequency spectrums, and waterfall spectrums.

Durable and Portable

WIth its rugged exterior design and battery-powered use, the PBS-4100+ is an ideal solution for on-wing engine vibration analysis and balancing. Enabling engineers to perform troubleshooting and diagnostics easily.
Trim Balancing

Sophisticated Trim Balancing

The elegance of the PBS-4100+ series is the concealment of the science behind a simple user interface. When vibration levels need to be reduced, the WinPBS Balancing Wizard gets the job done quickly and accurately. Trial weight and stored influence coefficient (“one-shot”) balancing methods are both supported.
System Expandability

Data Storage and Retrieval

Data Storage, Retrieval, and Reporting

Any data acquired with the PBS-4100+ can be saved and viewed at a later date, printed or transferred to other computers. All balancing and diagnostic information is stored by engine type and serial number for easy reference. Detailed reports provide complete information on every balance operation, including data readings, trial weights, and balance solutions.
Software configurable

Software Configurable Tracking Filters

Up to 7 unique tracking filters can be configured for each vibration channel. These filters can be used to track rotor synchronous components and other frequencies of interest. Default filters are used to correlate vibration content to the spools in the engine. User-defined filters can track possible faults on gearbox accessories. These tracking filters can eliminate the need for thousands of dollars of hardware and free up valuable rack space.
