Alloy Wire for Magnetostrictive Sensors in Stock

• Name:
  • Alloy wire for magnetostrictive sensors
  • Waveguide wire
  • Waveguide wire used for transducer
  • Waveguide wire used for sensor
• Property:
  • Magnetostrictive waveguide wire for level gauge level sensor 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 us, 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, ~ 3O00 m/s
