MTI Instruments, creators of industry leading aircraft engine maintenance diagnostic systems, continues their impressive legacy with their newest addition of the PBS-4100+ Portable Vibration and Balancing System, PBS Gen 4.

The PBS Gen 4 is designed for commercial aviation mobile applications, featuring a new high-visibility case and up to four hours of continuous use on a single battery charge.

Included in the new system is a third tachometer input, supporting three-spool engines and geared-reduction fans giving the technician more information than ever before. The frequency range has been extended to 25 kHz, to support turboshaft and APU testing which streamlines vibration survey and balancing processes.

With engine backup and restoration capabilities, users can be sure engine parameters are configured correctly every time.  While the unit reflects the latest in balancing system technology, it remains easy to use with limited training required, especially for technicians familiar with previous iterations of MTI's PBS systems.

New software has enhanced protection against online threats, with continuing updates provided, ensuring seamless workflow and limited downtime due to cybersecurity issues.

With vibration diagnostics that can help identify vibration sources and onboard spectral analysis finding potential problems before they occur, the system helps identify concerns before they become safety risks in-flight situations. With unique tachometer signal conditioning circuitry, speed signals from all engine types, as well as tachometer generators, add a higher level of diagnostics, available only to users of the PBS-4100+ system.
