QA2000 Accelerometer

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 stability

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 stability.

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.
