AI-Q-2020

Navigation-Grade Performance Accelerometer

Availability 

The lead time on the AI-Q-2020 is available for delivery in four weeks for quantities between the range of 5-20. Contact us for a quote. 

High-Performance Sensor

The AI-Q-2020 is built with Quartz Flexure technology to deliver true navigational grade performance. The AI-Q-2020 features an internal temperature sensor that allows the user to carry out temperature calibration and compensation, enhancing the bias, scale factor and axis misalignment performance over temperature.
