Some questions that are frequently asked about the K7L are given below. Use this information when selecting a model.
Can one K7L Amplifier be used for detection
in more than one place?
Yes.
By using Terminal Blocks to connect Sensing Bands in parallel,
detection can be performed in more than place with only one K7L
Amplifier.
Total: 400 m max.

Can a different terminal block (e.g. a
commercially available terminal block or a
terminal block constructed by the user) be
used instead of the one provided?
Yes.
When using another terminal block, however, be sure to check that
all the terminals are mutually isolated, and that there is no danger of
ground faults in connecting cables or Sensing Bands.
K7L-U
Note: 1. When wiring, be sure not to exceed the maximum possible
wiring distances for both the connecting cable and the
Sensing Band. Exceeding these distances may lead to
faulty operation. Connect one Sensing Band to each Termi-
nal Block.
2. Not applicable to the K7L-UD.
Can the K7L Amplifier be used as a
replacement for the 61F-GPN-V50 Water
Leakage Detector?
Yes.
Because the surge withstand capability is different, however, do not
use in locations where it will be exposed to impulses and surges,
such as outdoor roofs or in pump panels. Also, items such as the
power supply voltage and the connection sockets are different.
Check these items before application.
Can the K7L Amplifier detect pure water?
Yes.
Even pure water, which has a resistance exceeding 10 MΩ⋅cm, can
nearly always be detected if the K7L is used at its maximum sensitiv-
ity. This is because impurities are mixed with the water when it is
leaked and the resistance drops.

Can the K7L Amplifier detect oil?
No.
