• For the highest inertial navigation-grade performance available in today’s market, Honeywell Inertial & Sensor Systems produces the Q-Flex® Quartz Accelerometer 3000 (QA3000). Built on the same production line as the industry-standard QA2000 Accelerometer, the QA3000 Accelerometer has the same inherent quality, reliability, and long-term performance characteristics of the QA2000 Accelerometer. Primary applications include spacecraft navigation and control systems. 

• As with the entire Q-Flex family of accelerometers, the QA3000 features a patented Q-Flex etched-quartz-flexure seismic system. The use of an amorphous quartz proof-mass structure provides excellent bias, scale factor, and axis alignment stability. 

• The integral Q-Flex electronics develops an acceleration-proportional output current providing both static and dynamic acceleration measurement. Through the use of a customer supplied output load resistor, appropriately scaled for the acceleration range of the application, the output current can be converted into a voltage. The QA3100 includes a current-output, internal temperature sensor. Through the use of a temperature-compensating algorithm; bias, scale factor, and axis misalignment performance is dramatically improved.
