PRECAUTIONS FOR PROPER USE
.
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
2 ), CIF 3 , OF 2 (including gaseous state).
• 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.
• Use a commercial Fluorine resin
joint to mount the fiber.
• The bending radius of the protective
jacket should be R30 mm
1.181 in
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
ם
115 °C
ם
239 °F , place 100 mm 3.937 in or more
of the fiber in the normal temperature area to protect the
amplifier.
FD-F8Y liquid level sensing fiber
• 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.
