This QA2000 series Accelerometer. As the inertial navigation standard by which others are measured, It is the predominant sensor used in today's commercial and military aircraft strap-down inertial navigation systems. The long-term Repeatability and superior reliability characteristics of the QA2000 make it the best value inertial-grade accelerometer available on the market today. The QA2000 features a patented Q-Flex etched-quartz-flexure seismic system. An amorphous quartz proof-mass structure provides excellent bias, scale factor, and axis alignment Repeatability. The integral electronics develops an acceleration-proportional output current providing both static and dynamic acceleration measurement. By use of customer supplied output load resistor, appropriately scaled for the acceleration range of the application, the output current can be converted into a voltage. The QA2000 also includes a current-output, internal temperature sensor. By applying temperature-compensating algorithms, bias, scale factor, and axis misalignment performance are dramatically improved.
