A load sensor is provided comprising a magnetostrictive material and a wire. The magnetostrictive material may comprise an aperture, a first face, a second face, a thickness, and a first dado (groove or series of grooves). In the embodiment the magnetos trictive material is annular in shape with radial grooves on one face for locating the conducting wire. The wire is disposed at least partially in the first dado, wherein the first dado at least partially transverses at least one of the first face and the second face, wherein the wire at least partially transverses the first face and the second face. The load sensor may also comprise a magnetostrictive material having a first channel, and a wire disposed at least partially in the first channel, wherein the first channel passes between the inner and outer diameter of the magneto strictive material. Also, discloses is a method for measuring pressure using a magnetostrictive sensor where the load is determined from measurements of resistance or impendence and phase. |
