Magnetostrictive level measurement MS

Principle of Operation

  1. Current pulse is applied to one end of magnetostrictive wire.
  2. Circular magnetic is generated, encompassing the entire wire.
  3. Magnetic field from the position magnet and the circular magnetic field interact.
  4. The interaction produces a strain pulse.
  5. Travel time of the strain pulse to the pick-up is proportional to the distance the pulse travels.
  6. The time elapsed is measured multiple times.Remarkably accurate measurement is ensured.
