What is a magnetostrictive level sensor used for?

These level sensors are used as measured value pick-ups for the continuous recording of levels, and are based on determining the position of a magnetic float according to the magnetostrictive principle.

How does a level sensor work?

These level sensors work on the float principle with magnetic transmission. The float's magnetic system actuates a resistance measuring chain that corresponds to a 3-wire potentiometer circuit in the guide tube.

How does a built-in magnetic system work?

A float with a built-in magnetic system moves with the level of the medium to be measured on a guide tube which has one or more reed switch contacts built into it. The magnet actuates the contacts at the pre-set switching heights and thus allows individual levels to be monitored. The simple and tried-and-trusted principle of operation is suitable for a very wide range of applications.
