Q-Flex QA-1400

Single Axis Quartz Accelerometer

QA-2000

Cost-effective inertial-grade sensor

For the most cost-effective inertial-navigation grade solution, Honeywell produces the QA1400 for a variety of industrial and laboratory applications.

As with the entire Q-Flex family of accelerometers, the QA1400 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 measurements. By use of a customer supplied output load resistor, appropriately scaled for the acceleration range of the application, the output current can be converted into voltage.
