Title:
DEVICE FOR APPOINTING ANGLE IN VERTICAL DIRECTION
Document Type and Number:
Japanese Patent JPS5523489
Kind Code:
A
Abstract:
An accelerometer is provided which comprises a pendulum rotatable about an axis and which is arranged for measuring vertical angles. A rotatable device which is preferably of the moving coil type is located at the axis of rotation of the pendulum. The rotational device preferably comprises magnet arrangement for providing a constant magnetic field, and a movable coil which supports the pendulum for rotation and is rotatable in the magnetic field. The angle to be determined is measured by rotating the magnet arrangement about the axis from a reference position to the desired angular position and thereafter supplying current through the coil of such strength and polarity that the coil, and thus the pendulum is rotated about the axis of rotation from the vertical reference position it would normally assume due to the forces of gravity to the angular position of the magnet arrangement. The current required to effect such rotation of the pendulum is proportional to the angle to be measured.
