ABSTRACT:
An improved tilt meter mechanism characterized by a pyramidal pendulum support for a tilt sensor, and means for leveling the support to zero the sensor. A pair of motor driven gibs movable along vertical rails are provided, and a biasing mechanism urges angled faces of the support firmly against the gibs. To zero the tilt sensor, the motors associated with the gibs are individually actuated to move the gibs in directions substantially normal to the X-Y measurement plane of the sensor to bring the X-Y measurement plane into alignment with a gravitationally normal reference plane.
