K7L-U/K7L-UD

Liquid Leakage Sensor Amplifier for Long-distance Wiring

* Ordering information
* Specifications
* Configurations
* Dimensions, and etc

can be found in our PDF brochure.

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.

Features

A total distance of 400 m is achieved for cable and Sensing Band to minimize leakage damage.

1. Greatly expands the detection area. 2. Detects broken wires. 3. Helps to downsize gang-mounted panels. 4. Features a Noise Canceller (Patented)

Applications

1. Floor or Ceiling of Semiconductor or Flat Panel Display Factory. 2. Floor below Chemical Purification Tank
