Abstract :
Q-Flex quartz flexure suspension technology has evolved to produce a world class accelerometer with thousands of units delivered in 1991. The specification for the QA-3000 Q-flex design, supported by actual performance data, depicts performance characteristics superior in both bias and scale factor. Long-term measurements display bias and scale factor repeatability obtained across temperature over a period of three years. These data exhibit improved thermal behavior with reduced errors. Reaction time and radiation data highlight the performance of the hybrid position detector circuit. The Model QA3000 Q-Flex accelerometer is in production as a Sundstrand standard off-the-shelf product
