Title:
ACCELERATION METER
Document Type and Number:
Japanese Patent JPS53110583
Kind Code:
A
Abstract:
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.
