Main application

Chemical measurement and high precision measurement of blending tanks

Main feature

Based on the Wiedemann effect

High accuracy (±1mm/±0.1%F.S.) and high resolution

Low cost

Principle of Operation

Wiedemann effect

①Current pulse is applied to one end of magnetostrictive wire.

↓

 

②Circular magnetic is generated, encompassing the entire wire.

↓

 

③ Magnetic field from the position magnet and the circular magnetic field interact.

↓

 

④The 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.
