A transducer for creating an electrical signal proportional to the angular position of a member pivotally mounted on a given axis, which transducer comprises an element pivoted directly by the member and containing a means for creating a flux field linearly varying in intensity along a given operating line extending in an air gap between spaced portions and having a preselected arcuate shape. A linear Hall Effect device, with an output voltage proportional to the intensity of the flux field to which the device is exposed, is mounted at a fixed position on the operating line and in the air gap. Consequently, as the element is pivoted by the monitored member, the output voltage from the Hall Effect device varies proportionally to the position of the Hall Effect device along the operating line.

A transducer for creating an electrical signal proportional to the angular position of a member pivotally mounted on a given axis, said transducer comprising: an element pivoted directly by said member and containing a means for creating a flux field linearly varying in intensity along a given operating line extending in an air gap between two spaced portions of said operating line and having a preselected shape; a linear Hall Effect device with an output voltage proportional to the intensity of the flux field to which said device is exposed; and, means for mounting said Hall Effect device at a fixed position on said operating line and in said air gap whereby as said element is pivoted by said member to cause relative movement of said Hall Effect device along said operating line, said output voltage varies proportionally to the instantaneous position of said Hall Effect device along said operating line, wherein said flux field creating means is two permanent magnets each having opposite polarity poles and means for mounting said two magnets with like polarity poles of the magnets facing each other across said air gap, said magnets being mounted to rotate about a preselected axis, said like poles are generally parallel and at an angle with said preselected axis, and said operating line extends in a plane orthogonal to said preselected axis.
