Abstract:
An electronic angle indicator providing a digital indication for a desired angle comprises a pivotally suspended gravity responding pendulum retaining a ring magnet, a reference angle dial retaining a ring magnet and two magnetic field sensors, one for sensing magnetic field change of said pendulum and the other one for sensing magnetic field change of said reference angle dial. The output of said pendulum magnetic field sensor is compared with the output of said reference angle dial magnetic field sensor and causes the indicators display attainment of a desired angle orientation selected by said reference angle dial, or greater or lesser angle than the angle orientation selected by said reference angle dial.
