AI-Q-2020 Accelerometer

Navigation-Grade Performance Accelerometer

The AI-Q-2020 is a high-performance accelerometer, crafted with Quartz Flexure technology to provide true navigational-grade performance.

It features an internal temperature sensor that enables users to perform temperature calibration and compensation, significantly improving the bias, scale factor, and axis misalignment performance across varying temperatures. This makes the AI-Q-2020 an ideal choice for a wide range of modern, high-tech, and precision-guided systems that require consistent and accurate measurements.

For a more cost-effective solution, the AI-Q-2120 offers the same design and production process, maintaining the same performance parameters, but with a measurement range limited to ±15g, making it a suitable alternative for applications with lower measurement range requirements.

Key Performance

  • Navigation grade performance
  • High input range
  • Analog current output
  • High stability under temperature changes
  • High reliability
  • Internal temperature sensor for thermal compensation
  • Dual built-in self-test
Applications
  • Land & Marine Vehicles
  • Inertial Navigation Systems (INS)
  • Inertial Measurements (IMU)
  • Attitude and Heading Reference Systems (AHRS)
  • Orientation systems for the oil drilling industry
  • Train & rail measurement systems
  • Robotic systems control
  • Aircrafts, UAVs & Helicopters
