HW-group Wassersensor 1W-UNI

In critical infrastructures, water damage remains one of the most underestimated but dangerous risks. Even small amounts of liquid can trigger severe damage such as short circuits, corrosion, or IT downtime. The HW-group 1W-UNI Water Sensor is a precise point-detector designed to instantly recognize conductive liquids wherever they don’t belong – under racks, in technical rooms, or archives.

Unlike cable-based detection systems, the 1W-UNI sensor relies on four metal contacts and only triggers when fully wetted, eliminating false alarms caused by humidity or condensation. Its rugged design and plug-and-play compatibility make it indispensable in data center and industrial safety strategies.

Technical Features

• Point detection with 4 metal contacts for high accuracy
• 3 m RJ11 cable for flexible installation
• Fully submersible sensor, also detects standing liquid
• Compatible with Poseidon2, Ares, STE2, SensDesk and other 1-Wire UNI systems
• Automatic recognition with unique ID
• Horizontal or vertical mounting
• Durable, robust design for long-term operation

Benefits

• Accurate local water detection at defined points
• Minimized false alarms thanks to reliable trigger method
• Easy plug-and-play integration into monitoring systems
• Flexible setup with 3 m cable and multiple mounting options
• Reliable alerts via SensDesk cloud or SNMP
• Economical preventive protection of IT and production facilities

Typical Applications

• Data centers – under-rack water leak detection
• Server rooms – pinpoint leak monitoring
• Technical rooms – monitoring pumps, pipes, and HVAC systems
• Warehouses & archives – safeguarding sensitive goods & files
• Healthcare – protecting laboratory & analysis equipment
• Labs – preventive monitoring against chemical or process leaks

Integration

The 1W-UNI integrates seamlessly with HW-group hardware and cloud platforms. Users gain access to real-time event alerts, reporting, SNMP management compatibility, and multi-site SensDesk monitoring. Alerts can be delivered via email, SNMP traps, or SMS for rapid intervention.

Installation

Installation is simple: the sensor connects via RJ11 plug and is automatically recognized by compatible controllers. Its design allows floor-level mounting, wall installation, or hidden placement in less accessible spots. Its submersible capability ensures reliability even under larger leakage events.

Real-World Use

In data centers, installing the HW-group 1W-UNI under raised floors detects small cooling leaks early, while pharmaceutical labs use it with Ares monitoring to protect sensitive analysis systems from damage.

The HW-group 1W-UNI Water Sensor is a powerful point-detector for professional leak detection systems. With its reliable trigger principle, seamless integration, rugged housing, and submersible capability, it ensures maximum security for IT and industrial applications, making it a core part of modern water leak prevention strategies.
