Countermeasures Against Noise
Noise Canceller Function for Highly Sensitive Impedance
Detection
The K7L Liquid Leakage Sensor Amplifier detects liquids with
impedance as high as 50 MΩ and connects to the Sensing Band
through a cable that can be extended up to 50 meters.
Countermeasures against external noise are especially important for
the Sensing Band and connecting cable because they pick up
external noise like an antenna. The K7L incorporates the noise
canceller function described below.
Connected with 3-conductor Cable that Offsets Inductive
Noise (Patent Pending)
A VCT cable with three conductors (lines) is used. Line 1 is connected
to the Sensing Band and line 2 is left open. Lines 1 and 2 are almost
in the same position and thus will experience the same noise level.
The K7L obtains the difference between these signals. This means
that the noise signals in lines 1 and 2 are offset against each other
and a reading for the signal, without inductive noise, can be made.

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
terminal with a screwdriver∗ and insert the core from the side.
More Sensing Bands can be connected simply by wiring in an arch
shape.
Note: When you are finished working, sufficiently confirm that there is
an electrical connection.

Functions
Disconnection detection function (K7L-AT50D)
Operation While Monitoring for Liquid Leakage
•Short-wave signals (2.5 VAC, 3.75 Hz) for liquid leakage detection
are output from terminal 4 of the K7L.
•When there is no liquid leakage, the liquid leakage detection
signals that are output are interrupted by the Terminator and the
core of the Sensing Band will form an open loop.
Operation at Liquid Leakage Detection
•When liquid leakage occurs within the sensing range, the liquid
leakage detection signals output from terminal 4 are input to
terminal 2 through the leaked liquid.
•The voltage of the input signals will vary with the resistance of the
leaked liquid. This voltage is compared with the detection level set
at the K7L.
•As a result of the comparison, if the K7L determines that liquid
leakage has occurred, the K7L’s output LED will light, and the
liquid detection output will either turn ON or OFF.
Operation While Monitoring for Disconnection
•Output of disconnection detection signals starts within 2 s of power
being supplied to the K7L and is repeated at 7-s intervals.
•Disconnection signals are DC signals of 10 V max. that are output
for approximately 200 ms. During this time, the K7L is in
disconnection monitoring mode, i.e. it monitors for disconnections
only and the liquid leakage detection signals are stopped.
•If there is no disconnection, the disconnection detection signals
(10 VDC) that are output pass through the Terminator and return
to the K7L. The K7L takes this as normal, i.e., there is no
disconnection.
Operation at Disconnection Detection
•If there is a disconnection, the signals will be interrupted at the
place where the disconnection occurred, and will not return to the
K7L.
•If the signals do not return when the K7L is in disconnection
monitoring mode, it will determine that a disconnection has
occurred. The output indicator will flash, and the disconnection
output will turn ON/OFF depending on the position of the DIP
switch (right).

Note: 1. Disconnection detection is only performed between terminals 2 and 4. Therefore, be sure to connect the Sensing Band between
terminals 2 and 4.
2. The K7L will switch from liquid leakage detection to disconnection detection if either of the following conditions occur while liquid
leakage is detected.
•Disconnection occurs between the K7L and the place where liquid is leaked.
•While liquid leakage is detected, disconnection occurs between the place where liquid is leaked and the Terminator (F03-20T) and,
subsequently, the leaked liquid is removed (e.g., wiped up or dried).
3. During disconnection detection, liquid leakage will not be detected. Once disconnection has been detected, reset the power supply to
stop disconnection detection.

K7L-AT50/AT50D
Liquid Leakage Sensor Amplifier K7L Q&A
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.
K7L-AT50
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
Terminal Block.
2. Not applicable to K7L-AT50D.
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
Terminal Block.
2. Not applicable to 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 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.
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 sensitivity. This is because impurities are mixed
with the water when it is leaked and the resistance drops.
Can the K7L Amplifier detect oil?
In most cases, no.
If, however, it contains
impurities such as metal
powder, as is the case with
cutting oil and used engine oil,
detection may be possible
(actual instances of detection
have been observed). The
user should confirm whether
the required kind of detection is
possible before application.
