Water Leakage Detection Solution

Water Leakage Detector System protects facilities such as computer rooms, critical facilities, warehouses, and critical document rooms from water leaks and flooding accidents. The System is composed of at least one line type sensor that quickly detects water leaks along with a water leakage detector that alerts the water leaks to the user in a timely manner.


Features of TATSUTA’s Technologies

Safe and Reliable Sensors Utilizing Cable-making Expertise

Our line sensors do not fail to detect any water leakage at all points on its full length while remaining free from malfunction due to humidity. Our sensors can detect pure water, acid and alkaline solutions.

Superior environmental characteristics
A double-layered configuration is adopted that enables sensors to operate normally even at high temperature and humidity (60°C, 95%RH).

Small amount detection
Due to its excellent absorption characteristics, external braiding never fails to catch water leakage.


Easy Installation

our sensors are made of flexible materials and so are easy to install and use. They are located in low power circuits operating at a maximum of 12.5 VAC, which means they are very safe.

The sensors can be installed anywhere, including piping, floors, walls, and ceilings, contributing to creating a thorough detection network that has no blind spots.

Easy Identification of Leakage Points

Leak location detection
The detector has a digital display function that indicates the detected leak locations in meters.
It can also output data on leak positions.

Red coloration
The sensor part that has absorbed liquid turns red so you can visually confirm leaks more quickly, which enables prompt recovery.


We offers the following water leakage detectors as standard models, which are in control of one or more circuits according to the user's requirement. Each model incorporates a non-voltage output terminal that can be connected to a central monitoring panel.


For single-circuit systems (AD-AS-1DM)

This detector can be mounted to the DIN track in the panel and connected with DC power.


Non-coloration model (AD-S Sensor)

This line sensor detects even the slightest leakage of conductive liquids.

Coloration return model (AD-RS Sensor)

The part that has absorbed liquid turns red and then turns back to white when it dries.
