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 M
Ω
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
