Liquid Leakage Sensor Amplifier K7L-AT50 3
Liquid Leakage Sensor Amplifier
K7L-AT50
Ultra-miniature Sensor Amplifier Reliably
Detects a Wide Variety of Liquids Ranging
from Water to Liquid Chemicals with Low
Conductivity.
• Detects liquids with impedance as high as 50 MΩ using inter-
electrode resistance detection. Detection of IPA and pure water
is possible.
• Four selectable sensing ranges ensure detection suited to the
characteristics of the liquid.
• Incorporates a noise canceller circuit connected to a 3-conduc-
tor cable, ensuring a high level of noise immunity and reliable
operation (patent pending).
• The power supply block and Sensing Band are isolated, allow-
ing the installation of more than one device in the same place.
Ordering Information
Note: 1. Compared with the standard model, F03-16PE.
2. One F03-20 Terminal Block is included as an accessory with the K7L-AT50.
3. The minimum order for the F03-25, F03-26PES, or F03-26PEN Sensing Band Stickers is one set (contains 30 Stickers).
4. The minimum order for F03-20 Terminal Blocks, F03-26PTN Sensing Band Stickers, or F03-26PS Point Sensor Mounting Brackets is one
set (contains 10 Terminal Blocks, Stickers, or Mounting Brackets).
■ Available Sensing Band Lengths
Note: 1. To place an order for 1 m of the F03-16PE for example, specify F03-16PE-1M.
2. If you cannot find the length you need, please order the nearest larger length, then cut it to the required size.
Product name Model Characteristics
Liquid Leakage Sensor Amplifier K7L-AT50 ---
Sensors Sensing Band F03-16PE Standard model
F03-15 Greater durability and condensation resistance. (See note 1.)
F03-16PT Greater temperature and chemical resistance. (See note 1.)
F03-16SF Greater flexibility and superior workability. (See note 1.)
F03-16SFC Greater flexibility and enables visual confirmation when the inner color ap-
pears.
Point Sensor F03-16PS Easier to wipe off than the band type.
F03-16PS-F Electrodes have fluororplastic coating to resist chemicals.
