Accurately detect water leaks with sensors and detectors - '3M Leak Detection System'
We promptly and reliably detect and notify leaks inside equipment, piping, and water areas in data centers, semiconductor manufacturing sites, hospitals, and apartments.
The "3M Leak Detection System" adopts a method that detects the resistance between sensor electrodes. It is possible to combine a "detector" that performs judgment control with a "sensor" that detects liquids according to the application. 【Leak Detector】 - When detecting, the alarm lamp lights up, and it can output to an external alarm. - We offer a variety of models, from a general-purpose model with basic performance to models that can detect multiple locations, types that can be integrated into devices or walls, and models that can detect the location of leaks. 【Leak Sensor】 - There are two types: strip sensors and point sensors. The strip sensor is linear and can detect when part of the strip is submerged in liquid, allowing for monitoring of a wide area. - The point sensor can be installed at specific locations where leaks are anticipated or at drains where liquid accumulates, enabling efficient pinpoint monitoring. - The structure ensures that liquids on the sensor do not seep in and can be easily wiped off with a cloth, allowing for a smooth return to normal monitoring after a leak occurs. *For more details, please refer to the catalog PDF or feel free to contact us.

Line up（14）
| Model number | overview |
|---|---|
| WR-NA | [Leak Detection Sensor] A versatile model with basic functions for single-point detection. It can be powered by AC100V or 200V. |
| WR-M12-NW | [Leak Detection Sensor] A model capable of detecting multiple locations with 12 points. It includes preventive maintenance features that check for sensor dirt and noise levels to suppress false alarms and malfunctions. |
| WL-AD-2002-A | [Leak Detection Sensor] A compact embedded (plugin) model. Its small size allows for compact integration of the required number of detections within a distribution board. |
| WR-MPF | [Leak Detection Sensor] A model with position detection functionality (uses band sensor B-5P-EM). By using the sub-device WR-CPF, it can detect up to 40 points. |
| WR-B1 | [Leak Detection Sensor] A wall-embedded model for apartments and stores. |
| B-3P | [Sensor] A band-shaped sensor. It is a standard model designed to be laid on flat surfaces such as floors. |
| S-1F | [Sensor] A band-shaped sensor. It is a high-sensitivity model designed to be laid on flat surfaces such as floors. |
| S-1FP | [Sensor] A band-shaped sensor. It is a model designed to be wrapped around pipes and laid out. Please use cable ties for securing it. |
| B-5P-EM | [Sensor] A band-shaped sensor. It is a dedicated sensor for WR-MPF (leak detection sensor with position detection functionality) and is designed to be laid on flat surfaces such as floors. *Not usable with detectors other than WR-MPF. |
| PS-1R | [Sensor] A point detection type sensor. It is a model compatible with disconnection alarm functionality (incorporates terminal kit functionality). |
| PS-2 | [Sensor] A point detection type sensor. It is a standard model with simple functionality (not compatible with disconnection alarm functionality). |
| SS-1 | [Mounting Tool] A stainless steel mounting tool for securing 3M sensors. It is suitable for securing B-3P, PS-1R, and PS-2 sensors. |
| SS-5 | [Mounting Tool] A rigid PVC mounting tool for securing 3M sensors. It can be used for securing B-3P and B-5P-EM. It is used for laying conductive surfaces or in areas where it may be stepped on. |
| SS-6 | [Mounting Tool] An ABS resin mounting tool for securing 3M sensors. It is dedicated to the S-1F sensor. |

Distributors
3M Japan Co., Ltd. was founded in 1960 as the first local subsidiary of 3M in Asia. It imports and sells adhesive tapes, reflective materials, adhesives, abrasives, and other products, contributing to Japan's rapid economic growth. In 1961, it established the Sagamihara office, which has become the base for its current research and development activities. In 1970, it established the Yamagata office of 3M Japan Products Co., Ltd., which serves as one of the largest manufacturing bases in Japan and provides products not only to the 3M Japan Group but also to 3M companies overseas as a global "super hub."
