WLD Relay 1W-UNI Sensor – reliable leak monitoring with relay output

Sensor WLD Relay 1W-UNI

Water leaks are among the most critical risks for IT and industrial infrastructures. The HW-group Sensor WLD Relay 1W-UNI provides advanced area-based leak detection with relay output functionality, integrating seamlessly into HW-group monitoring ecosystems. It forms a reliable early warning system against water intrusion in server rooms, data centers, and industrial sites.

Unlike point sensors, the WLD Relay 1W-UNI monitors entire sensing cables, detecting even small amounts of water or glycol anywhere along the cable. Its 2D detection ensures full coverage, making it particularly effective under raised floors, near cooling units, or along pipelines.

Key Features

  • 1-Wire UNI connectivity – compatible with Poseidon2, STE2, Ares, Damocles
  • Relay output NO/NC (1 A / 30 V) for alarms, pumps, or sirens
  • Supports sensing cable lengths from 0.4 m up to 185 m total
  • 3 states: Normal, Leak detected, Cable disconnected
  • Reusable sensing cable after drying
  • Robust, flexible design, unaffected by bending or twisting
  • Easy installation using clips, tape, or screws

Advantages

  • Early leak detection across large areas
  • Relay output for active protection (e.g. triggering pumps)
  • Integration with IT monitoring and cloud platforms
  • Reliable alerts via email, SMS, SNMP, or SensDesk
  • Scalable solution with up to 185 m sensing range
  • Cost efficiency through reusable sensor cables

Application Areas

  • Server rooms and data centers – detection under raised floors and CRAC units
  • Telecommunications – secure base stations and network nodes
  • Industrial sites – monitoring glycol and cooling systems
  • Building management – archives, museums, or hotel infrastructures
  • Pharma and labs – protecting sensitive equipment

Integration

The WLD Relay 1W-UNI integrates directly with HWg monitoring platforms and the SensDesk Cloud. It allows real-time monitoring, SNMP traps for network management, automatic alarm notifications, and box-to-box communication with other HW-group devices. Together, it forms part of fully automated protection strategies.

Variants

  • Base set: Relay unit with RJ11 1-Wire UNI, relay output, PSU (optional)
  • Complete set: Includes 2 m WLD sensing cable, 2 m connection cable, relay, PSU, accessories

The HW-group WLD Relay 1W-UNI is a professional water leak detection sensor with relay output for immediate responses. Its 2D leak detection across the entire sensing cable, HW-group ecosystem compatibility, and flexible integration make it ideal for IT infrastructure, industrial monitoring, and building protection.
