Honeywell QA-3000高精度加速度計
Accelerometer
Highest inertial navigation-grade
performance
For the highest inertial navigation-grade performance available
in today"s market, Honeywell produces the Q-Flex? 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. An amorphous quartz proofmass structure provides
excellent bias, scale factor, and axis alignment stability.
The integral electronics develops an acceleration-proportional
output current providing both static and dynamic acceleration
measurement. By use of a customer supplied output load
resistor, appropriay scaled for the acceleration range of the
application, the output current can be converted into a voltage.
The QA3000 also includes a current-output, internal temperature
sensor. By applying temperature-compensating algorithms, bias,
scale factor, and axis misalignment performance are dramatically
improved.
