Abstract
A non-contact, current sensor includes a gapped magnetic core configured to circumscribe a current carrying conductor. A magnetostrictive element is mechanically coupled to the gapped magnetic core. Current flowing in the current carrying conductor induces a magnetic field in the magnetic core that flows through the magnetostrictive element. The gapped magnetic core is provided with mounting sections to which the magnetostrictive element is mechanically coupled. The mounting sections have a geometry that increases magnetic flux in the magnetostrictive element. A strain gauge is mechanically coupled to the magnetostrictive element to measure displacement in the element induced by the magnetic flux.
