Q-Flex QA-750 Single Axis Quartz Accelerometer
Honeywell’s Q-Flex QA-750 accelerometer is a cost-effective, single axis quartz sensor package designed for a broad array of high-performance marine and industrial applications for vibration measurement. As with the entire Q-Flex family of accelerometers, the QA-750 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.
