FD-F4/F9
Reliable liquid level
detection from outside
the pipe
Widely applicable FD-F41/F91 released
Easily mountable and adjustable
Durable up to 100 C 212 F
FD-F41/F91 can reliably detect the
liquid level inside a pipe made of, not
only, PVC, but also, acrylic or glass.
The range of applicable pipes has
been increased by this addition to
FD-F4/F9 (for 1 mm 0.039 in thick PFA
pipe).
Just attach it on a pipe with the tying
bands. The position can be easily
changed with the release lever even
after mounting, so that there is no
need to cut tying bands.
FD-F4 /F9 can operate under an
ambient temperature of 40 to 100 C
40 to 212 F. Hence, even hot
liquids can be safely detected.

Applicable pipe "6 to "26 mm "0.236 to "1.024 in
Compact body
FD-F4/F9 can be mounted on a
wide range of pipe diameters from "6
to "26 mm "0.236 to "1.024 in.
The body is just 13 mm 0.512 in thick
so that multi-level detection by
adjacent mounting at 13 mm 0.512 in
pitch is possible.
5 m 16.404 ft fiber cable length type is available
FD-F9 is attached with a 5 m 16.404 ft
long fiber cable. Hence, even if it is
used in an explosive area, the amplifier
can be installed outside the explosive
area.
Principle of detection
When the pipe is empty, the beam is
reflected from the inner surface of the pipe
wall and returns to the beam-receiving
part, since the difference in the refractive
indexes of the pipe and air is large.
When there is liquid in the pipe, the beam
enters the liquid through the wall and does
not return to the beam-receiving part,
since the difference in the refractive
indexes of the pipe and the liquid is small.
The beam reflected from
the inner surface of the
pipe wall returns to the
beam-receiving part.
612
The beam passes
through the wall
into the liquid.

PRECAUTIONS FOR PROPER USE
Refer to p.1135l for general precautions and p.90/p.121/p.141/p.168l for amplifier precautions.
This product is not a safety sensor. Its use is not
intended or designed to protect life and prevent body
injury or property damage from dangerous parts of
machinery. It is a normal object detection sensor.
Mounting
• Mount the fiber on a pipe with the attached tying bands
and anti-slip tubes as shown in the figure below.
Make sure that the release lever is retracted (position as
shown in the figure) before mounting.
Fasten two tying bands, as shown, and cut off the excess
portions.
Position adjustment
• In case of mounting on the pipe with tying bands, the fiber
position can be easily adjusted.
Adjustment

1 Unlock the release lever (in the
direction of the arrow).

2 Press the movable center holders

• If other tying bands are to be used, the dimension @
shown in the figure below should be 2.5 mm 0.098 in or
less.
Notes: 1) Whenever the mounting position is changed, adjust the sensitivity
again.
Notes: 2) The lever mechanism must be used only to adjust the position, and
not for tightening the tying bands. If tying bands are tightened while
the lever is open, and then the lever is locked, the fiber may be
damaged.
@
• In case of mounting using the two mounting holes, use M3
screws, plain washers, and spring washers.
The tightening torque should be 0.5 N m or less.
Please arrange the M3 screws, plain washers, and
spring washers separately.

PRECAUTIONS FOR PROPER USE
Refer to p.1135l for general precautions and p.90/p.121/p.141/p.168l for amplifier precautions.
Fiber attachment (FX-AT4)
• When the beam-emitting and beam-receiving fibers are
inserted into the fiber sensor amplifier (FX-301/302/303/311
series etc.), the enclosed fiber attachment for
FX-301/302/303/311 series facilitates insertion of the fibers
and reduces the possibility of incorrect fiber insertion.
For conventional amplifier
1 Thread the fiber cable through the gland and holder
separately, and screw the gland into the holder
clockwise.
Screw it clockwise
Cautions
• Take care that fiber attachment for
FX-301/302/303/311 series cannot be
used with fiber sensor amplifiers having
a pitch, between the beam-emitting and
the beam-receiving fibers, other than
7 mm 0.276 in. In case of fiber sensor
amplifiers having a pitch other than
7 mm 0.276 in, please use attachments
for conventional amplifier.

At this time, insert the attachment to a position at

How to use fiber cutter (FX-CT2)
1 Slide part @ of the fiber cutter fully upward till it stops.
2 Insert the fiber cables, mounted in the attachment, till
they stop.
Take care that there are separate fiber cable insertion
holes for "2.2 mm "0.087 in and "1.0 mm "0.039 in
or "1.3 mm "0.051 in fiber cables.
3 Slide part @ of the fiber cutter down to cut the fiber cables.
Part@
For "1.0 mm "0.039 in or
"1.3 mm "0.051 in fiber cables
Notes: 1) The fiber cables should be cut in one stroke.
2) Once a fiber cable is cut off at a hole, do not use the hole again, if
used, it degrades the cut surface quality and the detectability may
deteriorate.
3) The blade cannot be replaced. Please purchase an additional fiber
cutter, if required.
4) Note that the sensing range may be reduced by up to 20 %
depending on the cut condition. Hence, decide the setting distance
by taking sufficient margin.
Others
• Liquid in a pipe which is not transparent cannot be sensed
correctly.
• Unclear or highly viscous liquid may not be sensed.
• Fit the fiber head to the pipe securely, otherwise the
operation may be erroneous.
• Take care that no dew condenses on the pipe’s sensing
surface or the pipe’s inside wall and that no bubble
attaches on the pipe’s inside wall, since it can affect the
operation.
• If a liquid drop flows down across the sensing point or an
air bubble sticks on the wall at the sensing point, the
operation may be erroneous. Make sure that no bubble
arises in the liquid, and that no dew or liquid drop is
present on either surface of the pipe wall.
• Neither FD-F4 or FD-F9 is waterproof or chemicalresistant. Installation should be avoided at any place
where it could come in direct contact with water or
chemicals.
• Do not apply excessive tensile force to the fiber cable.
• Bending radius of the fiber cable must be R10 mm
R0.394 in or more. If the bending radius is smaller than
the specified value, the sensing performance may
deteriorate.
• Do not use the fiber at places having intense vibrations, as
this can cause malfunction.
• Keep the fiber head surface intact.
If it is scratched or spoiled, the detectability will
deteriorate.
• Do not expose the fiber cable to any organic solvents.
• Ensure that any strong extraneous light is not incident on
the receiving face of the fiber head.
• Take care that the sensor is not directly exposed to
fluorescent light from a rapid-starter lamp or a high
frequency lighting device as it may affect the sensing
performance.

Notes: 2) When ‘assist function’ is not used, the middle point of @ and b is
regarded as the optimum sensitivity point.
Notes: 3) In order to protect the mechanism, the sensitivity adjuster idles
when over turned, which may result in a backlash of 1 to 2
divisions.
Notes: 4) Depending upon the sensing conditions, stable sensing may be
possible at a position which is slightly shifted from the optimum
sensitivity point.
Notes: 5) Do not move or bend the fiber cable after the sensitivity
adjustment. Detection may become unstable.
