MTI Instruments Announces Newest Addition of the PBS-4100+ Portable Vibration and Balancing System

MTI Instruments announced their newest product addition, the PBS-4100+ Portable Vibration and Balancing System, “PBS Gen 4.”

“We are excited to announce our new PBS Gen 4 as it is fully portable, lightweight and rugged, and more importantly, it is the most powerful system in its class on the market,” said MTI Instruments’ president, Moshe Binyamin. “Additionally, this compact form factor system is designed to be used on the go with extended frequency range. We also expanded the capability set to include numerous innovative capabilities.”

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.

The PBS Gen 4 integrates features that ensure the system is easier to use than any PBS before it.

“The new cable check is a fantastic addition which, once it hits the market, I believe will quickly become the new standard in the future,” said Hamish Haridas, field service representative, Vital Link Europe Ltd. “The quick switch is also a great addition which will alleviate having to remind the operators that conducting vibration survey is in another ‘screen’, making balancing seamless.”

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

“The true differentiator is all of the technology and software packed into a simple easy to use interface,” said Ken Ameika, global director of Sales at MTI Instruments. “Today and tomorrow, when engine vibration levels need to be negated, the WinPBS balancing wizard will get the job done quickly and easily. It even supports both trial weight and stored influence coefficient balancing methods. There is no other system on the market that can do what the PBS-4100+ does as efficiently and easily.”

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.
