HW-group NB-WLD

Water damage is one of the most dangerous threats to IT and industrial infrastructures. Even small leaks can cause downtime, data loss, or severe equipment failures. The HW-group NB-WLD is a modern IoT water leak detector based on NB-IoT technology, offering reliable, energy-efficient monitoring with long battery life and cloud integration.

Unlike traditional LAN or WLAN-based systems, NB-WLD operates independently over NB-IoT networks, making it ideal for remote or shielded areas such as basements, technical rooms, or distributed facilities. With its Type A sensing cable, it detects even small amounts of water, condensate, or glycol along its entire length — providing reliable early warning and preventive protection.

Key Features

• NB-IoT connectivity for reliable operation in hard-to-reach areas
• Battery-powered with up to 3 years lifespan (optional 5V PSU)
• Supports Type A sensing cable, up to 60 m length
• Detects conductive liquids such as water, condensate, glycol
• Reusable sensing cables – dry and reuse after alarms
• Datalogger with 250,000 events stored locally
• Compact IP40 metal case, wall/desk/DIN-rail mounting
• Operating range: –10 °C to +70 °C

Benefits

• Reliable early leak detection prevents costly downtime
• Eco-friendly design with reusable cables
• NB-IoT makes deployments easy without LAN/WLAN installation
• Cloud integration with SensDesk or HWg-Cloud (free for up to 20 devices)
• Alerts via email, push, SMS, or phone calls

Typical Applications

• Server rooms – monitoring under raised floors and AC systems
• Data centers – detection of cooling leaks and condensate
• Building technology – basements, heating systems, storage rooms
• Museums & archives – protecting valuable collections
• Industry – monitoring pipelines, cooling circuits, and production areas

Integration
