Q-Flex® QA-2000 Accelerometer The inertial navigation standard As the inertial navigation standard by which others are The QA2000 also includes a current-output, internal temperature measured, Honeywell produces the QA2000. It is the sensor. By applying temperature-compensating algorithms, bias, predominant sensor used in today’s commercial and military scale factor, and axis misalignment performance are dramatically aircraft strap-down inertial navigation systems. The long-term improved. Repeatability and superior reliability characteristics of the QA2000 make it the best value inertial-grade accelerometer Features available on the market today. • • • • • • • As with the entire Q-Flex family of accelerometers, 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.
