AI-Q-550 Accelerometer

Accelerometer for High-Dynamic & Precision Systems

The AI-Q-550 accelerometer offers an impressive input range of ±80g, with one-year bias composite repeatability better than 1 millig, all housed in a compact, ruggedized casing designed to withstand high shock and vibration.

This performance makes the AI-Q-550 ideal for demanding applications in modern, high-tech, and precision-guided systems, where durability and precision are critical.

For a more cost-effective option, the AI-Q-560 provides the same design and production process as the AI-Q-550, offering identical performance parameters but with a measurement range limited to ±15g, making it suitable for applications that do not require the full input range.

Key Performance

  • Tactical grade performance
  • Good Bias
  • High input range
  • High stability under temperature changes
  • High reliability
  • Internal temperature sensor for thermal compensation
  • Miniature accelerometer with rugged design
Applications
  • Inertial Measurement Units
  • Flight Control Systems
  • UAV & ROV
  • Platform Levelling
  • Land & Rail Vehicles Systems
  • Inclinometers for industrial & drilling
  • Robotic systems
  • Structural Health & Maintenance
