Q-Flex

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.
