Q-Flex^® QA-2000
Accelerometer
The inertial navigation standard
As the inertial navigation standard by which others are
measured, Honeywell produces the QA2000. 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.
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.
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.
