Abstract
A rotary position sensor for sensing the position of an attached rotating object. The rotary position sensor uses a strain gage to detect the position of the object. The sensor includes a housing and a rotor located in the housing. The rotor is attachable to the object. A strain gage is positioned in the housing adjacent the rotor. The rotor rotates so as to contact the strain gage and apply a strain to the strain gage. The strain gage generates an electrical signal that is proportional to the position of the object.
