AI-Q-810 Measurement Grade Accelerometer

AI-Q-810 Measurement Grade Accelerometer

Quartz Pendulous Accelerometers for Industrial Systems

InnaLabs® Commercial Grade Accelerometers deliver true navigational grade performance. With a low measurement range of ±15g and excellent stability and long-term repeatability, the AI-Q-21XX is an optimal solution for high-accuracy commercial inertial measurement units and demanding applications.

Performance Statistics

  • Input Range +/- 15 g
  • One-year Repeatability <600 ppm
  • Temperature Sensitivity <180 ppm/°C

High-Performing Accelerometer

The AI-Q-810 fused quartz-based servo accelerometer offers a dynamic range of ±15 g with a one-year bias composite repeatability of 1,200 μg. It also has a quiescent power lower than 250 mW, in a compact and ruggedized casing that provides a high shock and vibration resistance, matching the highest industry standards at a very economical price.
