ABSTRACT:
An accelerometer has a liquid hydrostatic gimbal support. A pump is provided for circulating the liquid and a bellows allows for its thermal expansion. A sealed housing contains a pendulous mass and associated gimbal support geometry, and a pickoff and torquer are arranged in closed loop configuration, with the torquer current being indicative of an acceleration input.
