Abstract
A rotary position sensor for sensing the position of an attached rotating object. The rotary position sensor has a housing and a volute shaped rotor having a variable width that varies about the circumference of the rotor. The rotor is positioned within the housing and is attached to the object. The rotor rotates as the object rotates. A strain gage is positioned in the housing. The rotor contacts the strain gage and applies strain thereto such the strain gage deflects according to the variable width of the rotor. The strain gage generates a variable electrical signal that is proportional to the rotational position of the object.
