Applicable tubes
MaterialDiameter (Outside / Inside)
Silicone / PVCø4 × 2 mm
ø5 × 3 mm
ø6.4 × 3.2 mm (1/4 × 1/8 in)
ø9.5 × 6.4 mm (3/8 × 1/4 in)

Selectable tube removal direction

Mounting holes are designed to allow the sensor installation in two different orientations so that the tube removal direction can be selected.

Two mounting options to choose from

Monitoring for prevention of nonattachment of tube

When the Liquid Detection Fiber is used in combination with the 2-output fiber amplifier (FX-502, FX-502P), the tube / liquid condition can be indicated in three patterns.

* Please refer to the instruction manual for setting method of fiber amplifier. Before use, be sure to verify operation with your actual tube under your application conditions.

Flexible and robust fiber core allows for easy tube routing.

The fiber core withstands bending radius of 2 mm 0.079 in and is flex-resistant.

Flexible and robust fiber core allows for easy tube routing.

Notes:
1) It may not be possible to sense cloudy liquid, liquid with different refractive index, or liquid with high viscosity (liquid that causes the light to disperse).
2) Due to variations in the fiber amplifier's displayed values, a bending radius of R4 mm or more is recommended.

Cautions For Use

  • Never use this product as a sensing device for personnel protection.
  • In case of using sensing devices for personnel protection, use products which meet the laws and standards, such as OSHA, ANSI and IEC etc., for personnel protection applicable in each region or country.
  • Firmly install the tube into the bracing arms. When installing the tube, make sure that the tube is in close contact with the sensing part. If it is not in close contact, the sensing performance may be affected.
  • The tube is expected to be installed to and removed from the sensor manually approx. 3,000 times. However, periodically check the bracing arms and light intensity and replace the product if necessary.
  • As water drops adhered to the sensing surface will affect the sensing performance, carefully check if dew condensation is not formed on the external surface of the tube. Also note that water drops running along the inner wall surface of the tube or bubbles adhered to the inner wall surface will affect the sensing performance.
  • 耐Do not use the sensor in a place where it is exposed to water or chemicals because the sensor is neither waterproof nor chemical resistant.
  • Take care that the sensor is not directly exposed to fluorescent lamp from a rapid-starter lamp, a high frequency lighting device or sunlight etc., as it may affect the sensing performance.
  • Be careful not to apply excessive tensile force to the fiber part.
  • Be sure to cut the fiber before installing it to the fiber amplifier.
  • When inserting the fiber into the fiber amplifier, use the fiber attachment (accessory).
  • Do not apply any stress (such as excessive bending or pulling) to the fiber attachment after installing the fiber to the fiber attachment.
