Rack-mounted PBS-4100+ Vibration and Balancing System

PBS-4100R+ Test Cell Vibration and Balancing System

The “one-shot” balancing solution for test cells is now enabled for ARINC 429 and 664 data.

Designed for the vibration analysis and jet engine trim balancing of commercial and military aviation gas turbine engines, the PBS 4100R+ quickly isolates engine problems and locate troubles. Long renowned for its rapid configurabilty and intuitive user interface, it can now leverage digital data from the aircraft’s Engine Monitoring Unit (EMU) or Electronic Engine Controller (EEC) for streamlined engine vibration testing with reduced wiring and hardware.

To test a turbine engine, the operator executes a vibration survey, slowly cycling the engine speed from idle to maximum, then back down to idle. What is special about the PBS-4100+ is how it measures the vibration contribution from each of the spools and graphically records its findings on a series of plots that correlate to how the engines can best be rebalanced.
