Engine vibration and balancing systems now support ARINC 429 and AFDX data
28/07/2025
MTI Instruments, a Vitrek brand, has announced the latest update to its industry-leading PBS-4100 family of engine vibration monitoring systems, which now fully support ARINC 429 and ARINC 664 (avionics full-duplex switched Ethernet (AFDX)) digital data interfaces.
This enhancement significantly expands the compatibility of the PBS-4100+ and PBS-4100R+ systems with modern engine platforms, including those on the Airbus A320neo, Boeing 737 MAX, Airbus A350, Boeing 787 and more. Leveraging digital data from the aircraft’s engine monitoring unit (EMU) or electronic engine controller (EEC), this update enables streamlined engine vibration testing with reduced wiring and hardware.
“By adding ARINC 429 and AFDX support, we are future-proofing the PBS-4100R+ and simplifying the testing process for modern digital aircraft,” said Ken Ameika, Vitrek’s Vice President of Global Sales. “Technicians can now acquire engine speed and vibration data directly from the aircraft’s digital buses, reducing set-up time and potential sources of error.”
