For Q-Flex technology in an economical package, Honeywell produces the QA750 for a broad array of moderate performance
applications including: high-speed train car leveling, building tilt and sway monitoring and seismic sensing.
As with the entire Q-Flex family of accelerometers, the QA750 features 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 measurement. 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.
As an option, the QA750 can be provided with the temperature-compensating algorithm where bias, scale factor, and axis misalignment performance are dramatically improved.
