When requirement for more safe, convenient and low the magnetic field of permanent magnet inside cost. the float is moved into to the proximity of the The float switches are extremely compact, simple reed switch inside the stationary stem, the reed and are easy to install on any small space. switch "snaps" the contact together and closes These switches are not effected by electrical the electrical circuit. When the magnetic field is interference. They can withstand to chemicals, moved away from the reed switch, the reed high temperatures and pressures if the correct switch does not touch. The circuit is open. material of float switch is selected by the customers.
4 LIQUID PROPERTIES AND FLOATS
When the liquid specific gravity is less or more closed N S than the water, the float on the switch will either magnet increase or decrease the immersion depth. The switch actuation level will also change. open All actuation levels are assumed with the water (SG=1). If your liquid has a different specific gravity, you should not specify the float specific (Fig. 1) gravity more than liquid, that will not cause the float rise with the liquid level. The reed switch inside the stationary stem will not be activated by the magnet inside the float. Fig. 2 illustrates the method of perpendicular actuation (such as the FC V TYPE float switches). If your liquid has a high viscosity, you should When the magnetic field of ring magnet inside specify largest size float that will provide a the float is moved into the proximity of reed greatest buoyant force to ensure the units switch inside the stationary stem, the reed switch operate normally. "snaps" the contact together and closes the Because the float switches are activated by the electrical circuit. When the magnetic field is magnetic field of permanent magnet inside the moved away from the reed switch, the reed float, make sure the liquid is no iron powder or switch does not touch. magnetic material to avoid magnetic The circuit is open. interference.

Such high induced voltages (transients) may cause damage to the reed switch or significantly reduce its life. H Therefore, protective circuits such as: RC (snubber), varistor or clamping diodes are recommended.
