A Quartz Flexible Accelerometer is provided for detecting acceleration which employs an amorphous quartz proof-mass structure clamped at raised points between upper and lower portions of a magnet structure. As the accelerometer is accelerated, the proof-mass structure is displaced thus changing the capacitance.An acceleration-proportional output current is developed 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.
The entire QFA family of accelerometer produced by OELABS has over ten members,which are widely served in aerospace, aviation, ships, weapons, petroleum and geotechnical engineering. As with the QFA family of accelerometer, the QFA-06A-1 features the highest inertial navigation-grade performance available in today's market, and the QFA-06K, used in petroleum drilling, is environmentally rugged and low cost.
