Features

For use with leak detection or liquid detection fiber only

The FX-301-F7 (Note 1) dedicated for the leak detection fiber FD-F71 and the FX-301-F dedicated for the liquid detection fiber FT-F93 are available. Optimal setting is possible with easy operation.

Note: The FX-301-F can be also used by setting it to leak detection mode. However, the functions are different from the FX-301-F7 dedicated for the leak detection fiber, so it is recommended to use the FX-301-F7 when using the leak detection fiber.

For use with leak detection or liquid detection fiber only

Easy maintenance, as main and sub units are identical

Both main and sub units utilize the same amplifier body. This feature allows for easy mounting in the side-by-side configuration. The main and sub unit functions are distinguished only by the proper use of 3-core main cable and the 1-core sub cable.
Moreover, by utilizing the same body for both main and sub units, inventory management and maintenance is simplified.

Sets the optimal threshold value [FX-301-F7]

Threshold value will be set automatically to -20 % of the incident light intensity during the teaching to steadily detect the leak. It is also possible to change the threshold value to -15 % or -30 %.

Threshold follow-up function [FX-301-F7]

Incident light intensity is checked at regular time interval (10 min.), and threshold value is reset automatically.
*Function is set to OFF at the time of factory shipment.

Flashing function incorporated

When the leak detection fiber is connected (F7 mode), if a leak is detected, you will recognize which fiber detects the leak at a single glance because the emitter will start flashing.

Long life and stable operational settings due to the newly developed emitting element

The newly developed “four-chemical emitting element” used for FX-301-F7 / FX-301-F can suppress the secular change of the light emitting element to minimum, allowing stable detection for long period of time.

Easy to operate with individual / collective teaching mode

Individual teaching mode (TEACH)

Optimal threshold value is set automatically on FX-301-F7 just by setting the MODE indicator to “TEACH” and pressing the jog switch.
(The threshold value is set after selecting the liquid detection fiber for FX-301-F.)


Collective teaching mode (ALL)

Teaching is performed collectively for all the connected amplifiers with an optical communication function when the MODE indicator is set to “ALL”. Each amplifier will be set with an optimal threshold value.
At the same time, other setting in the master unit will be copied to the slave unit.

Low profile liquid detection fiber with high chemical resistance

■Labor-saving design
・Because all you need to install is one screw, one-touch mounting of the fiber head is possible.
・Replacement parts even for resetting after a leak are unnecessary.
・Because the fiber head is simply designed, wiping off leaks is rendered easy.

FD-F71

■Superb explosion resistance / chemical resistance
Explosion resistance is enhanced by adopting the fiber method (SEMI S2 compliant). The head unit made of fluorocarbon polymers also has superb chemical resistance.


■Stable detection performance
The unique effect of capillarity enables reliable detection of small leaks and viscous liquids.

■Compact, space-saving
This slim (10 mm 0.394 in) side-mounting fiber head is especially good for use in confined spaces.

■Amplifier built-in type photoelectric sensor is also line-up [EX-F70 / EX-F60]

Stably detect the liquid inside the pipe!

■Stable design that doesn’t permit liquid-absent or sensor errors

・When liquid is present, its effect on the lens causes light to focus and enter.

・When abnormalities such as a severed or removed fiber or a cutoff cable occur, light does not enter and the sensor will output the same as “liquid-absent”.

■Reliable detection not affected by bubbles or droplets
Latest optical fiber techniques have solved problems caused by bubbles, droplets or liquid leakage that arise in conventional pipe-mountable fiber heads.


■Superior explosion resistance compatible to SEMI S2
Because there is no electric circuitry in the fiber head, it boasts excellent explosion resistance.

■Easy to use and reliable detection
Even when the shape and thickness of the pipe vary, this fiber head uses a method where the beam axis follows the diameter of the pipe, and so when compared to conventional methods, the shape and thickness of the pipe have no influence over the performance of this fiber head.
