Q-Flex QA-650 Single Axis Quartz Accelerometer

Q-Flex QA-650 Single Axis Quartz Accelerometer

Economical Single Axis Quartz Accelerometer for Industrial Applications 

Honeywell’s Q-Flex QA-650 accelerometer is an economical, single axis quartz sensor package designed for industrial applications where accuracy, durability and quality are critical.

As with the entire Q-Flex family of accelerometers, the QA-650 features a patented Q-Flex etched-quartz-flexure seismic system and its 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.
