Q-Flex® QA-750 Accelerometer Cost-effective inertial-grade sensor For Q-Flex technology in an economical package, Honeywell As an option, the QA750 can be provided with the produces the QA750 for a broad array of moderate temperature-compensating algorithm where bias, scale performance applications. factor, and axis misalignment performance are As with the entire Q-Flex family of accelerometers, the QA750 dramatically improved. features patented Q-Flex® etched-quartz-flexure seismic Robust design and quality assurance provides superior system. An amorphous quartz proof-mass structure provides reliability. 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 a voltage.
