• For the most cost-effective inertial-navigation grade solution, Honeywell Inertial & Sensor Systems produces the Q-Flex Quartz Accelerometer 1400 (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. The use of an amorphous quartz proof-mass structure provides excellent bias, scale factor, and axis alignment stability. 

• The integral Q-Flex electronics develops an acceleration-proportional output current providing both static and dynamic acceleration measurement. Through the use of a customer supplied output load resistor, appropriately scaled for the acceleration range of the application, the output current can be converted into a voltage.

• As an available option, the QA1400 also includes a current-output, internal temperature sensor. Through the use of a temperature-compensating algorithm, bias, scale factor, and axis misalignment performance is dramatically improved. Performance may be enhanced by the application of optional bias and scale factor thermal models supplied by Honeywell. Implementation of thermal modeling may result in bias residual errors as low as ±200 µg and scale factor errors as low as ±400 ppm. For additional details, please contact Honeywell.
