PRECAUTIONS FOR PROPER USE
Fiber
FT-L8Y/V8Y chemical-resistant type fiber
Do not use it in the following chemicals:
Dissolved alkali metals (Natrium, Potassium or Lithium),
Fluorine gas (F
), CIF
, OF

3
The beam axis mark is indicated on the side-view fiber.
Perform the beam alignment with the beam axis marks, on
the receiver and the emitter, facing each other.
Mounting
Use a commercial Fluorine resin
joint to mount the fiber.
The bending radius of the protective
jacket should be R30 mm
or more. It will be damaged under
the value.
The bending radius of the bear
fiber should be R25 mm
R0.984 in
or more. The sensing range will be
shortened under the value.
Do not subject the fiber under tension.
Although the chemical-resistant type fiber is rated for use
up to
115 °C
239
°F, place 100 mm
of the fiber in the normal temperature area to protect the
amplifier.
FD-F8Y liquid level sensing fiber
Mounting
Use a commercially available fluorine resin joint, etc., to
install FD-F8Y.
Cautions
Take care that unclear liquid may not be sensed stably.
Take care that the tube may stretch by maximum 2 % of
the total length if it is used at a high temperature.
Do not scratch the fiber jacket while cutting the fluorine
resin tube.
