Reliable protection against water leakage with the HW-group WLD water detection chain A

HW-group WLD Water Detection Chain A

In environments such as server rooms, data centers, archives, or industrial facilities, even minimal amounts of water can have devastating consequences. Short circuits, damaged hardware, data loss, or complete production outages are typical scenarios following an undetected leak. With the WLD Water Detection Chain A from HW-group, a professional solution is available that ensures reliable area-based water detection and provides effective protection against water ingress.

The detection chain was specifically developed to detect conductive liquids such as water or ethylene glycol along the entire cable length. Unlike spot sensors, which measure only at a single point, this system works over a complete area and can detect even the smallest amounts safely. The result is an early warning system that prevents damage before it occurs. At the same time, the reusability of the sensor cable ensures long-term cost efficiency.

With lengths of 2, 10, and 50 meters and a maximum total length of up to 85 meters per zone, the system offers high flexibility. In combination with extension cables (WLD Prolong Cable A), the monitoring range can even be extended to up to 185 meters. This makes the WLD Water Detection Chain A suitable for large server rooms as well as targeted monitoring of technical installations.

Installation is simple and requires no special expertise. The cable can be attached to walls, floors, or along pipelines – regardless of bending radius, twisting, or pressure. After a leak, the sensor cable can be dried and reused, minimizing operating costs.

Technical Features and Advantages

Area-based water detection: liquid detection along the entire cable length.
Status messages: 0 = OK, 1 = Flooded, 2 = Cable interrupted.
Length variability: Available in 2 m, 10 m, and 50 m; total length expandable up to 185 m.
Robust design: resistant to bending, twisting, and pressure.
Reusable: can be cleaned and dried after a water alarm for reuse.
Wide compatibility: works with HWg-WLD, HWg-WLD Relay, SD-WLD, WLD2, and Perseus Monitoring.
Extended monitoring: integration into network environments via SNMP, e-mail, and alarm systems.

Integration into Monitoring Systems

The WLD Water Detection Chain A can be seamlessly integrated into the HW-group monitoring ecosystem. Via platforms such as the SensDesk Portal or HWg-Cloud, events can be logged, reports generated, and alarms distributed via e-mail or SNMP. Thanks to open interfaces, integration into third-party systems is effortless, providing optimal control for network or building monitoring.

Summary

How does the WLD Water Detection Chain A differ from spot sensors?

Spot sensors measure liquid only at a single point. In contrast, the WLD chain detects water along the entire cable length, covering a significantly larger protection area.

Can the sensor cables be reused after a water leak?

Yes, the cables are reusable. After cleaning and drying, they can be used again without any issues.

How long can the total length of a monitored zone be?

Up to 85 m of sensor cable and with extension cables up to 185 m total length can be connected per zone.

WLD sensing cable A - Water detection chain

The sensor cable is a core component of the HW group water leak detection system and works in combination with devices such as HWg-WLD, HWg-WLD Relay, SD-WLD, WLD2, or Perseus Monitoring 140–155.

The cable detects even the smallest amounts of liquid and immediately triggers an alarm, which can be forwarded via e-mail, SNMP traps, or other monitoring systems. A key feature is its reusability: after a leak, the cable can be cleaned, dried, and reused, helping to reduce long-term costs.
