A strain-free sensor includes a conductor extending from a first end to a second end through an intermediate portion. The conductor has a first coefficient of thermal expansion. A coating is bonded to the intermediate portion of the conductor. The coating has a second coefficient of thermal expansion that is distinct from the first coefficient of thermal expansion. A tube is disposed about the conductor. The tube includes an inner surface provided with a plurality of projections. The conductor is slidingly arranged within the tube with the plurality of projections being configured and disposed to establish a substantially friction-free interface between the tube and the conductor forming the strain-free sensor. |
