An accelerometer having an electromagnetic spring for restraint of an axially movable accelerator mass. The spring comprises at least one magnetic field transverse in direction to that of the mass and at least one conductor in the field, carrying current, for generating a restoring force during relative movement between the field and the conductor, the force being varied by varying the current flow to the conductor. A positive indicator comprises a first winding fixed mechanically to the mass and a second winding fixed to the casing of the accelerometer. The first winding carries a-c and the second winding receives an induced a-c signal with amplitude proportional to the acceleration, its phase position indicating the direction of acceleration.

Accelerometer

A spring system has an adjustable spring force and includes at least one magnet. The magnet has a magnetic field, and at least one conductor passing direct current is disposed in the magnetic field. The magnet is formed by a number of pole pairs disposed along the path of displacement of the conductor, and each of the pole pairs encloses an air gap; the current-carrying conductor is a wire.
