Multi-Axial Accelerometer

Product overview

The Multi-Axial Accelerometer is an essential component in L3Harris' advanced accident-survivable flight recording systems designed for use in commercial and military aircraft. The hermetically sealed instrument houses single-, dual- or tri-axial sensors for measuring vertical, longitudinal and lateral acceleration.

  • Meets the mandatory requirements of the FAA and other regulatory authorities
  • Compliant to ARINC 542A/573/717/747 and certified to TSO C124b
  • Lightweight, easily customizable, long-lasting and hermetically sealed for harsh operational environments
  • Direct replacement for other ARINC-compliant accelerometers

Key Features

Hermetically sealed for safety

When something goes wrong in an aircraft, for whatever reason, it’s critical that investigators have enough information to reconstruct the conditions and factors that lead up to the problem. With a hermetically sealed housing, your single-, dual- or tri-axial sensors will be ready to tell their stories – even in the toughest, harshest operational environments.

 

Designed for long operational life

The lightweight Multi-Axial Accelerometer is designed to give you peak performance, with a MTBF rating of than 50,000 hours. That’s a long time by any measure and it means that you won’t be worrying the status of the accelerometer for at least the next 5.7 years (assuming you used it 24 hours a day during that period without ever turning the unit off).
