- Power generating equipment, power plants
- Pharmaceutical, food, water treatment, environmental engineering industries
Level transmitters with a magnetostrictive, high-resolution measuring principle are used for continuous level measurement of liquids. They are based on determining the position of a magnetic float following the magnetostrictive principle. The level transmitters are mounted on the outside of a bypass level indicator.
This magnetic field of the float tensions the wire. The superposition of these two magnetic fields triggers a mechanical wave in the wire. This is converted into an electrical signal at the end of the wire in the sensor housing by a piezoceramic pick-up.
The measured propagation delay enables the origination point of the mechanical torsional wave to be determined with high accuracy.
