Magnetostrictive waveguide wire for level gauge and displacement sensor

• Magnetostriction is a property of ferromagnetic materials such as iron, nickel, and cobalt. When placed in a magnetic field, these materials change size and/or shape

• An important characteristic of a wire made of a magnetostrictive material is the Wiedemann effect
• When an axial magnetic field is applied to a magnetostrictive wire, and a current is passed through the wire, a twisting occurs at the location of the axial magnetic field
• The twisting is caused by interaction of the axial magnetic field, usually from a permanent magnet, with the magnetic field along the magnetostrictive wire, which is present due to the current in the wire
• The current is applied as a short-duration pulse, -1 or 2 µs, the minimum current density is along the center of the wire and the maximum at the wire surface
• This is due to the skin effect

• The magnetic field intensity is also greatest at the wire surface
• This aids in developing the waveguide twist
• Since the current is applied as a pulse, the mechanical twisting travels in the wire as an ultrasonic wave
• The magnetostrictive wire is therefore called the waveguide
• The wave travels at the speed of sound in the waveguide material, - 3O00m/s

Application:

• Magnetostrictive level gauge
• Magnetostrictive level sensor
• Magnetostrictive position sensor
• Magnetostrictive displacement sensor
• Magnetostrictive linear displacement transducer
• Magnetostrictive transducer
• Other sensors where magnetostrictive wire needed
