MEDER Level Sensors operate on a direct, simple principle.
In the vertically mounted models, a float encircling a stationary stem is equipped with powerful, permanent magnets. As the float rises or lowers with the liquid level, the magnetic field generated from the magnet within the float actuates a hermetically sealed, magnet reed switch mounted within the stem. The stem is made of Polyamid or Polypropylene, depending on the type of liquid. Reed switches with different power characteristics can be used.
The side-mounted unit uses a different actuation methode because of its horizontal attitude. The basic principle, however, is the same: as a direct result of rising or falling liquid, a magnetic field is moved into the proximity of a reed switch, causing its actuation. Reed switches with different power characteristics can be used.
