F(C)D Magnetic Float Level Switch_B0

Magnetic Float Level Switch
www.fine-tek.com
INTRODUCTION
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).

FEATURES
Multiple points measuring, multiple level points
could be for custom-made.
The housing protection is at least IP65.
Rugged construction and multiple options for
materials from engineering plastics as PVDF,
PP, PVC, and stainless steels such as SUS304,
SUS316, float switches can be applied to
versatile applications in chemical corrosion
of acidity and alkalinity liquid, solvents or oil
fuels.
Employing the magnet to actuate the reed switch
requires no power.
Life expectancy of each contact can reach up to 2
million times.
All output signal wiring are simplified in same
junction box (housing) to economize the external
wiring construction.
The reed switch and lead wire are isolated
with liquids absolutely. All stainless steel
switches are applicable to high pressure and
high temperature environment.
FC(D) type magnetic float level switches are more
cost-effective than other level switches in terms of
multiple points.

CONTACT PROTECTION CIRCUITS
INDUCTIVE LOADS
When using a reed switch with inductive
loads such as motors, relays, solenoids, etc.,
The contact will be subjected to a high
induced voltage during opening of the
contact (load circuit).
(Fig.1)
Such high induced voltage (transients) may
cause damages to the reed switch or
significantly reduce its life.
Therefore, protective circuits such as: RC
(snubber), varistors or clamping diodes are
recommended.(refer to Fig.1)

. It is prohibited to connect directly with any solenoid valve, motor or magnetic switch.
CAPACITIVE LOADS
When using a reed switch with capacitive
loads such as capacitors, incandescent lamps
or long cables, the contact will be subjected to
a high surge (inrush) current.
Therefore, protective circuits such as:
surge suppressors or current limiting resistors
are recommended.(refer to Fig.2)

ORDER SPECIFIED
THE PROPERTIES BETWEEN LIQUID AND FLOAT
Please choose the proper float subject to above independent specified terms and chemical characters.
4. Chemical: Please use plastic float for acid/
alkaline corrosion of chemical
applications. PVDF float is noted
for high temperature cases.
1. Temperature: PVDF Max. 120BC,
PP Max. 80BC,
SUS304/ 316 Max. 200BC
2
2. Pressure: SUS304/ 316 Float, Max. 35kg/cm
Engineering plastic, Max. 5kg/cm2
(S10 float Max. 50kg)
3. Viscosity: Please choose smaller S.G. with
greater diameter floats to cope with
high viscosity liquid applications.
5. Benzine: Please choose stainless steel floats
to apply in any gasoline, fuel oil,
petroleum application.
6. S.G.: The float S.G. Must be smaller than the
liquid, otherwise, the liquid buoyancy
can not deliver the float upword.
Buyer's guide :
The magnetic level switch can be done as per
customer's specified technical data such as
the flange, thread, housing, float ball diameter,
float ball number, the float traveling up or down
actuated position by N.C. or N.O. output, the
total float working distance (L) or each
independent float actuating position, please
refer the order information to define the
application specifications. A single ball driving
multiple actuated points is available to apply
on the order form.
Example: FD B HM 7 S6 3 0405
Material Housing Type Connection Stem (Tube) Type Float Type Float Number Total Float Working Distance
A= Minimum distance from the mounting
position to the highest actuation level.
It is requested the minimum interval for a single
ball driving dual actuated positions (D) or
neighboring two balls (B), or from the bottom to
the lowest ball interval (C) or from the mounting
position to the first ball (A), otherwise, there will
be some magnetic mutually interference involved
by insufficient interval. To ensure the defined
distance, please see the data below:
B= Minimum distance between any two
actuation levels.
C= Minimum distance from end of the lowest level.
D= Minimum distance between two actuation levels
by one float.

VERTICAL ADJUSTMENT TYPE
Applicable at tank interior pressure under
5 kg/cm2.
Standard specification 80BC, special order
of max. 200BC available.
Switch contact: 20W/150Vac /250Vdc SPDT
50W/300Vac /350Vdc SPST
60W/220Vac /500Vdc SPST
60W/400Vac /1000Vdc SPDT
Customer specified flange/ screw
acceptable.
This is a special design for some liquid
applications requiring monitoring different
actuation levels frequently. The user needs only to

screw/ flange up or down to achieve the
actuated level position adjustment.

The "N.O." Means normally opened circuit of the reed switch (off) in lower liquid
level. As the float moves up to the specified higher level, the circuit closed (on).
The "N.C." Means normally closed circuit of the reed switch (on) in lower liquid
level. As the float moves up to the specified higher level, the circuit open (off).

FlneTek
INSTALLATION
The float level switch should be
mounted far away from liquid inlet.
Any strong liquid fluctuation will
produce error output signals.
It is advised to place a pipe shield or
equivalent device to normalize the
switch actuation if the switch is used
near agitator.
It had better require an L type
supporter, when the switch is
mounted in concrete wall tank as
figure below.
It is recommended to select the
standpipe with diameter larger than
the float ball for installation process.

NO C NC
Means that the NO-C circuit will be close while liquid level higher than the float ball,
and NC-C circuit will be close while liquid level lower than the float ball.
Please screw the housing cap tightly and fix the conduit outlet, it will reinforce the housing
performance against the moisture and direct water. (f8mm multiple cord is recommended
for wiring)
If the end user is intended to adjust the actuation level position independently, please move
the float ball(s) position as well as the interior reed switches, otherwise, it will appear an
error or no signal.
