Q-Flex® QA-750 Accelerometer
Description
Cost-effective inertial-grade sensor
For Q-Flex technology in an economical package, Honeywell produces the QA750 for a broad array of moderate performance applications.
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 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.
As an option, the QA750 can be provided with the temperature-compensating algorithm where bias, scale factor, and axis misalignment performance are dramatically improved.
Robust design and quality assurance provides superior reliability.
