Abstract
A linear position sensor for sensing the position of an attached object. The linear position sensor uses a strain gage to detect the position of the object. The sensor includes a housing and a ramp shaped actuator located in the housing. The actuator is attachable to the object. A strain gage is positioned in contact with the actuator. The actuator applies a strain to the strain gage as the actuator is moved. The strain gage generates an electrical signal that is proportional to the position of the object.
