Easy operation even for beginners!
Optimum settings can be realized with simple operations

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.

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 %.

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.
