HW-group Water Sensor 1W-UNI

Water ingress is one of the greatest threats to sensitive technical infrastructures. Even the smallest amounts of moisture can cause significant damage – from server failures and production downtime to costly repairs of IT and facility systems. The HW-group Water Sensor 1W-UNI 3m is a reliable device that detects liquids precisely at the point of contact, ensuring efficient protection against water leakage. Specifically developed for accurate detection of conductive liquids, it is an indispensable component in modern monitoring and security systems.

The special feature of the 1W-UNI water sensor is its ability to detect liquids at a specific point. It operates with four conductive metal contacts that trigger an alarm only when they are fully immersed in water. This prevents false alarms caused by humidity, condensation, or brief splashes. This dependable technology makes the sensor ideal for critical environments such as server rooms, data centers, or technical facilities where absolute precision in water detection is essential.

A key advantage is the 3-meter RJ11 connection cable. This allows flexible placement of the sensor precisely where the risk of water ingress is highest – under server racks, along wall sections, or in hard-to-reach corners. Thanks to its plug-and-play compatibility with devices such as Poseidon2, Ares, or STE2, the sensor can be easily integrated into existing monitoring systems without major installation effort. It thus provides not only protection but also quick and simple handling.

With its robust design, submersible construction, and the option for horizontal or vertical installation, the HW-group Water Sensor 1W-UNI 3m is a versatile tool for leakage monitoring. It ensures reliable prevention of water damage and contributes to the long-term security of critical infrastructures. From data centers to archives and laboratories, this sensor delivers precise liquid detection exactly where it matters most.

Why the HW-group Water Sensor?

The HW-group Water Sensor 1W-UNI 3m combines precision, ease of use, and reliability. It offers companies and institutions a cost-efficient way to prevent water damage. Direct integration into HW-group monitoring solutions ensures that alarms can be executed in real time – either via local systems or through the SensDesk platform (paid) for remote monitoring and central alarm distribution. This makes the sensor one of the most effective tools against water ingress in complex infrastructures.

How does the Water Sensor 1W-UNI 3m detect water?

The sensor operates with four metal contacts on the underside. An alarm is triggered only when all of them are fully covered with water. This effectively prevents false alarms.

Is the sensor suitable for direct contact with water?

Yes, the water sensor is fully submersible and can operate even when placed directly in water without losing functionality.

Can I easily integrate the sensor into my existing system?

Yes, with a 3-meter RJ11 cable, the sensor is directly compatible with HW-group devices such as Poseidon2, Ares, or STE2 and is ready for immediate use.
