As with the entire Q-Flex family of accelerometers, the QA3000 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. The QA3000 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.
