K7L-U/K7L-UD

Liquid Leakage Sensor Amplifier for Long-distance Wiring

Ultra-miniature Liquid Leakage Sensor Amplifier Enables Longest Liquid Leakage Monitoring Distance in Industry

• Stable detection of liquids with impedance as high as 1 MΩ using inter-electrode resistance detection. Detection of chemical liquids and pure water is possible.

• Higher noise immunity with a noise canceller circuit connected to a 3-conductor cable.

• Prevents electrode corrosion with an AC detection method.

• The power supply circuit and detection circuit are isolated, allowing several Amplifiers to be installed in the same place.

• After a disconnection is detected, operating status is held to eliminate instability due to contact of the disconnected part. (See note.)

Note: For the K7L-UD.
