Abstract
An accelerometer employing a magnetic fluid bearing which permits movement f a magnetic cylinder along a designated sensitive axis. The device is used to measure acceleration in such applications as inertial platform leveling, thrust termination, and inertial reference triads. The position of the magnetic cylinder (proof mass) is measured by a capacitance bridge network. The output of this capacitance network is a voltage which is proportional in direction and magnitude to the applied acceleration. This voltage will be amplified by an operational amplifier.
