Abstract
An angle measuring device for establishing a position of a frame member in two orthogonal planes or in an azimuth plane, relative to a reference plane, comprising a frame member supporting a plurality of equally radially and angularly spaced linear potentiometers having rods which engage a base plate and are pivotally connected thereto to permit the frame to be swiveled in any location about the base plate. The potentiometers are calibrated to provide an indication of the position of the frame relative to the base plate as a result of movement of the rods within the potentiometers.
Claims14
An angle measuring device, comrising:
- a frame;
- means providing a reference plane;
- means interconnecting said frame and said reference plane means for two dimensional pivotal movement of said frame about a fixed location in said reference plane means, and for sensing the relative angular position between said frame and said reference plane means and providing electrical signals indicative of said position, and including a plurality of spaced sensing means disposed about an axis in said frame which intersects said reference plane at said fixed location, each said sensing means including a rod mounted in said frame for longitudinal movement parallel to said axis and pivotally connected to said reference plane means;
- and
- means receiving said signals and providing an indication of said relative angular position.
An angle measuring device comprising:
- a frame;
- a base plate;
- a plurality of equally angularly spaced parallel rods disposed about a central axis in said frame and pivotally connected to said base plate;
- sensing means mounted in said frame and receiving at least some of said rods for sensing the position of said rods relative to said sensing means and providing electrical signals indicative of said relative positions;
- and
- means receiving said signals and providing an indication of the relative angular position between said frame and said base plate.
