摘要： An accelerometer includes a housing, a magnetic fluid within the housing, and an inertial body suspended in the magnetic fluid and generally constrained to move along a single axis. Centering magnets are positioned on two sides of the inertial body along the axis. A detector provides a signal indicative of acceleration based on displacement of the inertial body. A plurality of stops can be placed on the inertial body inside the housing. A coil winding can be placed on the housing to be coupled to the inertial body for maintaining the inertial body substantially in place. Cavities with air can be on sides of the inertial body. Openings in the housing can be placed at locations of the cavities. The inertial body can have a channel connecting the cavities. The detector can be a Hall sensor, a digital Hall sensor, or two Hall sensors for differential detection of the acceleration. The housing can have two lids that substantially enclose, within the housing, magnetic fields from the centering magnets.
