Towards a hybrid current monitoring system: Nickel and GMM comparison as magnetostrictive transducers

In this paper, the magnetostrictive aspects of nickel and Terfenol-D are compared, in order to carry out the development of magneto-optical current sensing devices. The design and construction of the transducers are described, whereas their response when submitted to magnetic fields, with and withou...

Description
Summary:In this paper, the magnetostrictive aspects of nickel and Terfenol-D are compared, in order to carry out the development of magneto-optical current sensing devices. The design and construction of the transducers are described, whereas their response when submitted to magnetic fields, with and without temperature compensation, is evaluated.
