PRINCIPLE
The single unit or multiple reed switch units are housed tightly in stainless steel or engineering plastic stem, and the permanent magnet is sealed into the middle of the specified float ball(s). You can mount the float ball to penetrating through the stem, then the liquid buoyancy will deliver the float ball up and down at the specified position by graduating rings.
When the float internal magnet approaches the reed switch, it will actuate the reed switch contact point to create an open or close circuit. We can apply such on-off output signals to reach liquid level controlling and monitoring purpose. The figures below show the float orientations on N.O. (Normal Open) and N.C. (Normal Close).


The FC/FD Series is a magnetic float level switch product line. They are top mounted units designed to provide cost-effective multiple switch points using a single entry point into the vessel.

FDX Magnetic Float Level Switch, Lquid Level Switch

The FC/FD series is a magnetic float level switch product line based upon two principles, buoyancy and magnetism. The floats of the FC/FD magnetic float level switch are designed for a specific minimum fluid density (specific gravity), based upon the volume and weight of the float elements. The floats contain a magnet and the stationary stem can incorporate the reed switches corresponding to each float. The reed switches open or close their electrical contacts when the magnetic element in the floats come in contact with the reed switch locations in the stem. The reed switches will reverse their contact state when the magnet in the float element moves away from the location of the reed switches in the stem. The FC/FD float level switch is more cost effective than competing technologies when multiple switch points are required from a single point of entry in a vessel.
