Magnetostrictive Level Sensors are devices used to measure the level of liquids in tanks or containers. They operate based on the principle of magnetostriction, where a magnetic field interacts with a material to produce a mechanical strain. This strain is converted into an electrical signal, allowing for accurate level measurement. These sensors typically consist of a float that moves along a rod containing a magnetostrictive wire. As the float rises or falls with the liquid level, it creates a pulse in the wire, which is detected and processed to determine the exact liquid level. They are known for their reliability and precision in various industrial applications.
