摘要：
A linear accelerometer comprises a proof mass in the form of a permanent bar magnet located in a tube containing a magnetic fluid such as a liquid with particles of magnetic material suspended therein. A servo circuit responsive to A.C. energized sensing coils is used to energize a D.C. electromagnet to maintain the proof mass in a central position in the tube.
