AI-Q-550 Accelerometer

Control Grade Miniature Sensor

The AI-Q-550 is a tactical grade miniature accelerometer, built with Quartz Flexure technology. Offering an input range of ±80 g with one-year bias composite repeatability better than 1 millie g, in a compact and ruggedized casing that provides a high shock and vibration resistance matching the highest industry standards. Ideal when tactical grade performance, small dimensions robustness & reliability are required.

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
