Q-Flex® QA-650 Accelerometer
Description
Quartz flexible accelerometer, as a kind of force feedback pendulum accelerometer, is developed on the basis of liquid floating pendulum accelerometer. The difference between the two mainly lies in that the detection mass of quartz flexible accelerometer is not floating, but is connected to the flexible beam support elastic torque is introduced. Therefore, this kind of accelerometer has higher accuracy, strong anti-disturbance ability, large measuring range and strong overload ability.
For Q-Flex technology in an economical package, Honeywell produces
the QA650 for industrial grade applications including: automotive
test
instrumentation, braking system deceleration, bridge and building
sway and tilt monitoring, industrial and robotic control, land
vehicle navigation,
subway and high-speed train ride comfort control, and offshore
drilling platform motion monitoring.
As with the entire Q-Flex family of accelerometers, the QA650
features a 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.
