Q-Flex QA-3000 Single Axis Quartz Accelerometer
Overview
Engineered to use the same form factor as the QA-2000, the Q Flex QA-3000 Single Axis Quartz Accelerometer packs a lot of performance and value, proving the same inherent quality and reliability customers have come to know from Honeywell Q-flex accelerometers.
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 QA-3000 has three performance grades to best meet customer’s performance requirements.
