Comparison of a Cube-Textured-Nickel and a Nickel-200Magnetostrictive Ring Transducer.

摘要

The magnetic and magnetostrictive properties of a magnetostrictive scroll-wound ring transducer made from cube-textured nickel were measured and compared to the corresponding properties of a ring transducer made from conventional Nickel 200. Both transducers were separately excited in air at low-power linear drive levels with varying induction fields of magnetization,and their electrical input impedances were measured. Some in-water measurements were also made on the two rings at nearly optimum values of induction field. The data obtained can be used to choose the type of ring and the induction-field level of operation which will best satisfy a given requirement. (Author)
