Sensing Band
F03-16PE/-16PT/-15/-16SF
Chemical Resistivity for F03-16PE/-16PT
Note: 1.
A: Not affected at all or only very slightly affected.
B: Slightly affected but, depending on the conditions, sufficient for use.
C: Affected but may still be used. (Replace the Sensing Band immediately after detection.)
2.
In order to prevent secondary fire damage, consider the effect of the atmosphere of the environment and the solution to be detected on
the Sensing Band.
3.
If the Sensing Band changes shape or color when a liquid is detected, replace the Sensing Band.

Connecting the Sensing Band
Bending the Sensing Band
To change the direction of the Sensing Band, bend the Sensing Band
in one or two places where the core is not exposed.
Note:
Bend the Sensing Band approximately 4 cm (i.e., twice the dis-
tance between places where the core is exposed) away from
places where a Sticker is attached. If the Sensing Band is bent
at places further away than this, the Sensing Band may come
away from the surface.
Stripping and Connecting Terminals
1.
Cut into the Sensing Band approximately 4 to 6 cm in from the
end as shown in the diagram below.
2.
Strip away approximately the last 9 mm of the sheath to expose
the core (SUS line).
3.
To connect to the Terminal Block, push down the top of the termi-
nal with a screwdriver and insert the core from the side. (Refer to
Dimensions
on page 9.) More Sensing Bands can be connected
simply by wiring in an arch shape.
Note:
Check that the wiring is secure before using the K7L in applica-
tions.
Interval Between Stickers
When securing the Sensing Band with Stickers, attach the Stickers
at intervals of 20 to 30 cm in places where the core is not exposed.
Note: 1.
When using the F03-26PES (adhesive-tape model), be sure
to wipe all moisture, oil, and dust from the surface to which
the Sticker is to be attached. Failure to do so may result in
insufficient adhesion, and the Sticker may peel away from
the surface.
2.
When using the F03-26PEN (screw model), before install-
ing the Sensing Band, it is necessary to perform stud weld-
ing. For details on the pitch of the studs, refer to the
information on the dimensions of Sensing Band Stickers.
