FF Side Mount..

Side Mounting Float Switch
www.fine-tek.com
INTRODUCTION
WORKING PRINCIPLE
FEATURES
The reed switch relies on two basic scientific principles namely: buoyancy and magnetism.
Buoyancy causes the float (which contains a
magnet) to rise with the liquid and magnetism
helps open and close the switch.
A change in liquid levels raises or lowers the float
up or down. The end of the pivot arm (non float
side) contains a permanent magnet that can
repel the switch magnet (inside the stationary
‘stem’ of the entire structure).
The side mounted float level sensor (FF series)
are manufactured specifically for horizontal
mounting on tanks or vessels. They work well as
high or low level controls.
1. Both Micro-Switch types and Reed Switches
are available. The MicroSwitch type is usable
even at ambient temperatures of 100° C maximum.
2. Mounting flanges are custom-made. (JIS,
DIN,ANSI).
3. A wide variety of floats for different solution’s
specificgravities (S.G.) are available.
4. Wetted parts material ranges from plastics,
stainless steel, anti-corrosive and explosion
proof types.
When the float magnet moves close to the
switch’s stationary stem, the float magnet repel
the switch magnet which either opens or closes
the Electrical circuit.

IMPORTANCE FOR INSTALLATION
1. SUS304/SUS316 materials are not available
for corrosive application.
4. Check the liquid’s S.G. level before
installation.
2. The cable duct(s) must face downward to prevent moisture seeping in.
5. The mounting hole must be larger than
the external diameter of the float. (Please
refer to p2)
3. The float and extension rod must be inserted
into the bin completely.
6. Don't mount the devices near the bin's
inlet or outlet.
