No specialized technician required for the installation and removal of tube
When the Liquid Detection Fiber is used in combination with the 2-output fi ber amplifi er (FX-502, FX-502P),
the tube / liquid condition can be indicated in three patterns.
Liquid Detection Fiber accepts tubes that
are commonly used with cell culture
apparatus.
Mounting holes are designed to allow the sensor installation
in two different orientations so that the tube removal
direction can be selected.
● Dedicated tool and cable ties are required for the
replacement of tube.
● Risk of tube damage if the tube is replaced by a
person not familiar with the replacement procedure.
● The tube and sensor must be secured in place by
tightening the cable ties with appropriate tightening
force to prevent tube deformation.
● Sensitivity adjustment must always be made after
tube replacement.
